Celebrate the Large and Long Program: Colours of the Outer Solar System Origins Survey (Col-OSSOS)

Celebrate the Large and Long Program! is a series of blog posts which showcase the high-impact science under the Large and Long Program of Gemini Observatory.

What is the Large and Long Program?

The Large and Long Program (LLP) is one of five observing modes Gemini offers to users of our telescopes. These five modes categorize projects based on length and weather conditions required for the observations. Classically, Gemini accepts proposals on a six month basis and recipients awarded with observing time complete their observations within that given semester. Large and Long Programs, on the other hand, provide more flexibility for long term research and last anywhere from one to three years. This extended time frame promotes collaboration across communities and produces significant and high-impact science. Here, we ask past and present Large and Long Programs to share a little about their research and experience with Gemini Observatory.

1. Principal Investigator: Name and Affiliation?

Wes Fraser. Astrophysics Research Centre. Queen’s University, Belfast

2. How would you describe your Large and Long Program?

The Col-OSSOS program (Colours of the Outer Solar System Origins Survey) is designed to gather surface colours of roughly 120 Kuiper Belt Objects using both the Gemini North and Canada-France-Hawaiʻi telescopes, simultaneously. This use of dual telescopes enables us to gather observations in the ultraviolet, visible, and near-infrared. With these observations we will be able to determine each object’s compositional class. The ultimate goal is to produce the first ever quantitative compositional-dynamical map of the outer Solar System, with the aim of identifying key hallmarks of certain features of Neptune’s migration, including blue interlopers in the cold classical region, or an abundance of low inclination, red objects in the 2:1 resonance that have been swept up from the cold classical region.

3. Why is Gemini best suited for this research?

Gemini is one of the few telescopes in the world that has the large aperture, excellent location, and most importantly, the necessary imaging cameras covering the wavelength range we need and the ability to rapidly switch back and forth between those cameras. No other telescope in the world possesses that particular killer combination, making the Gemini telescopes, and in particular, Gemini North, the only tool for the job.

4. What has been the best part of your experience with the Large and Long Program?

Getting to know the telescope staff and the telescope itself is the best part. Each observatory has a personality. Knowing that personality is the best way to maximize personal use of the telescope. A really big part of that is getting to know the staff, which is very difficult when operating remotely, or in queue fashion. The Large and Long Programs have given me the opportunity to shake hands with all the staff that operate this telescope.

Name:  Alison Peck

What is your current position and at which telescope?

I am an Instrument Program and User Support Scientist at Gemini North

In four lines or less, explain what you do as part of the Gemini Observatory team?

I am working mostly on the Visitor/Community Instrument programs.  I also spend part of my time working with the Science User Support Group

How long have you worked for Gemini?

8 months

Where are you originally from/where did you grow up?

I’ve moved around a lot, all my life, mostly in the US and Europe. I lived in Hilo several years ago, and I liked it enough to come back.

In three lines, explain your PhD thesis.

I studied the gas falling into supermassive black holes in galaxies.  This helps to put an estimate on the mass of the black hole, and to characterize the physical environment in the central parsecs near the active galactic nucleus.

What are your current research interests?

I still study the central regions of active galactic nuclei at a variety of wavelengths.

What is your favorite movie?

Blade Runner, but Primer is a pretty close runner-up

What is one hobby of yours?

Walking.  I like to walk to work, I like to go hiking, anything outdoors where I can look at plants, animals, weather, etc.

Favorite beverage?

Ginger lemonade

Name: Kathleen Labrie

What is your current position and at which telescope?

Observatory Scientist working in the Science Users Support Department based at the Northern Operations Center in Hilo, Hawaii.

In four lines or less, explain what you do as part of the Gemini Observatory team?

Most of my time is spent coordinating the development and maintenance of the data reduction software suite.  I also code a bit, write documentation, do quality assessment, help users, support some internal software.  And I do astronomical research too.

How long have you worked for Gemini?

13 years

What drew you to this job?

During the PhD, I realized that I really liked the technical aspect of astronomical research, especially the software development (coding) aspect.  Playing with data through software while serving our users is the main appeal of the job for me.

What is the best part of your job?

Coding.  Debugging software, finding the source of mysterious behavior, can be as fascinating as it can be frustrating.  At the end there’s this “Ah! ah! Got you” moment that can be very rewarding. Basically, it all comes down to problem solving, whether it’s debugging or coding new stuff.

Where are you originally from/where did you grow up?

Born and raised in Rouyn-Noranda, Québec, Canada.  A small town 8-hour drive from Montréal.  A land of endless forests and countless lakes.  Beautiful.

What skill do you think is most important to know for your job?

I would say that a good balance of pure logic and intuition is important.  Both are essential to problem solving, especially when it comes to data processing and software.  They help me target the root cause of a problem efficiently and correctly.

Why is astronomy important?

Astronomy is a great gateway science to get kids and adults alike interested in science and technology.

In three lines, explain your PhD thesis.

I developed a technique to use near-infrared emission lines from supernova remnant shells to estimate supernova rates and the impact of  supernova activity on starburst galaxies.

What are your current research interests?

I am still highly interested in my research project, however I have not been able to work on that for years.  These days I am part of a team that studies the broad emission line regions of quasars (the region just beyond the accretion disk.)  We are trying to estimate the mass and size of the quasars, and how things move in there.

What is your favorite movie?

The Godfather. I’m still undecided whether I prefer the first or the second movie.

What is the latest book you have read?

Winter Men.  It follows two German brothers during WWII.  Beautifully written, and translated (from Danish).  Beware, not a cheerful story.

What three albums would you bring with you to a desert island?

I don’t listen to music much anymore.  It’s a bit strange. Pink Floyd’s The Wall would have to be one of the three.  It is  possibly the only album I never get tired of.  Then Jean-Michel Jarre’s
Oxygène, and a recording of Mozart’s Requiem.

What is one hobby of yours?

Geocaching, which can be defined as “Using multi billion dollar military defense satellites to find tupperware in the woods.”  We use GPS to find small containers hidden by other geocachers, just for fun. Check it out at geocaching.com.

Favorite beverage?

Hendrick’s Cucumber Martini.  Crush a couple slices of cucumbers, add gin (Hendrick’s, it has to be Hendrick’s), a bit of dry vermouth, ice. Shake and pour in martini glass.  Heaven.

Get to Know Gemini! – Mischa Schirmer

Get to Know Gemini is a new series of blog posts aimed to highlight the different careers, backgrounds, and types of people contributing to Gemini Observatory and its science.

Name: Mischa Schirmer

What is your current position and at which telescope?

I’m an assistant scientist at Gemini South.

In four lines or less, explain what you do as part of the Gemini Observatory team?

I spend about 20 nights per year as a night-time observer, executing the observing plans and doing an initial quality assessment. At other times I prepare the observing plans, oversee the progress of our programs, help our users, maintain and develop software tools, and keep a watchful eye at our instrumentation.

How long have you worked for Gemini?

A bit more than 5 years.

What drew you to this job?

It is a very interdisciplinary job. I love all aspects of observational astronomy, and the best place to be is at a large observatory. There, everything comes together. Researchers submit their observing programs to us, we help them optimize the setup, get the data for them, and provide post-observation support. I find this very rewarding because I help other people explore the Universe in the best possible manner… and I like that I can contribute much more to our understanding of the Universe than through my own research projects alone (which I like very much, nonetheless).

What is the best part of your job?

It’s always exciting. I see research unfold long before it gets published, and I can help it along the way with my technical and scientific experience. I often see that my work makes a difference to others, and that is very rewarding and motivating.

Where are you originally from/where did you grow up?

I was born and grew up in southern Germany, near Munich.

What skill do you think is most important to know for your job?

That’s a good one. At first I wanted to say “technical and scientific experience”. But the real answer, I think, is curiosity. The best scientists are curious. Because curiosity makes you want to understand how things work, find ways to improve and fix them, and explore new ways forward. That applies to all aspects of my job. The skills, and the technical and scientific experience then come automatically.

Why is astronomy important?

Because astronomy tells us that we don’t need to worry that the Sun will extinguish tomorrow and life on Earth will uncomfortably quickly freeze to death. Because conservation of angular momentum tells us that the sun will rise again tomorrow. Because space begins just 100km above our heads (many people commute more than that), and it is a much thinner layer of thin air that protects us from the deadly vacuum and the radiation out there. When you think about it… it’s scary! Astronomers and the laws of physics tell you not to worry, we checked!

We are taking many things for granted, because they seem “natural”, but they are not. To most of us, the Universe is far away and unimportant. That is not true. All protons, neutrons and electrons in your body were formed in a hot beginning 13 billion years ago; stars fused them into larger nuclei such as carbon and oxygen, without which our metabolisms would not work, and we would suffocate in minutes. The gold in your wedding ring and in the circuitry of your computer was forged by the violent death of a giant star that lived before the Sun came into existence. Some of the very same atoms in your body were perhaps once part of a fearsome Tyrannosaurus Rex, it’s eyes, it’s claws, or perhaps it’s teeth? Ultimately, astrophysicists strive to understand where the Universe came from, and how it managed to grow stars and planets capable of supporting life. It gives meaning to everything, it provides the big context.

In three lines, explain your PhD thesis.

My PhD was focused on finding the most massive structures in the Universe, clusters of galaxies. Because clusters are so massive, they optically distort the images of distant background galaxies. I have developed a method based on this lensing effect to identify clusters.

What are your current research interests?

I study supermassive black holes in the centers of galaxies, and how they grow over time. Even though these black holes are tiny compared to a galaxy, they can release enormous amounts of energy, severely messing things up. For example, they may shut down a galaxy’s capability to form stars such as our Sun. There is a very large number of open questions in this area that will keep astronomers busy for decades to come.

What is your favorite movie?

I don’t have one.

What is the latest book you have read?

“The Cavemen”, from Joern Lier Horst. Horst worked as a crime investigator for the Norwegian police before he became a writer. His crime stories are excellent page turners.

What three albums would you bring with you to a desert island?

None. I’d enjoy the nature, peace, and spend all day snorkeling and scuba diving until the nitrogen levels in my body tissues reach critical values.

What is one hobby of yours?

Observing and taking pictures of the night sky with my self-made telescope. Unfortunately, it’s locked up far away because I could not bring it along when we moved to Chile.

Journey Through the Universe 2017

Journey Through the Universe 2017

The Universe is expanding… and so is the Journey Through the Universe program! From March 13-17, 70 observatory professionals and informal educators are extending their reach to districts across the Big Island. Journey Through the Universe (to be referred to as Journey in the rest of this post) includes: classroom visits for students in Hilo-Waiākea, Honokaʻa, Paʻauilo, and Waimea in grades 2-12, StarLab Portable Planetarium shows for Hilo-Waiākea students in K-1, workshops for teachers, including a workshop for 40 teachers from the Kaʻū-Keaʻau-Pāhoa Complex area to introduce the Next Generation Science Standards (NGSS) and a NASA Lunar and Meteorite Sample Certification Workshop led by NASA Solar System Exploration Research Virtual Instituteʻs (SSERVI) Brian Day and Joseph Minafra, as well as a public colloquia titled, “Discovery, New Frontiers, and Solar System Exploration,” by NASAʻs Brian Mitchell.

“Sustaining a program the size and magnitude of Journey is no small feat,” says Journey Team Leader Janice Harvey. “With the continual expansion of the Journey program year after year, itʻs obvious that the impact this program has on our local students and the community is substantial.”

Check this post every day during the week of Journey classroom visits for pictures and descriptions of the dayʻs events!

Classroom Visits – Friday, March 17th

On the last day of classroom visits, we followed Gemini astronomer André-Nicolas Chené and administrative specialist Natalia Gonzalez to Kalanianaʻole Elementary and Middle School. Students built 3-D models of well-known constellations and discovered that, although the constellations may look 2-D to us on Earth, each star in the constellation is a certain distance away and are often not right next to each other!

Chené hands out styroform boards with constellations attached.

Students answer Chené’s questions.

Students construct their own 3D constellations!

Career Panel at Waiākea High School

One of the newer additions to the Journey program is the inclusion of career panels made up of local observatory professionals. Wednesdayʻs panel included: Canada-France-Hawaiʻi Telescope (CFHT) Director Doug Simons and Les Mizuba, Subaru Telescopeʻs Kiaina Schubert, W. M. Keckʻs Mike Aina, and Geminiʻs John Vierra and Alexis Acohido. Thursdayʻs panel included: W. M. Keckʻs Rich Matsuda, Shelly Pelfrey, Leslie Kissner, CFHTʻs Grant Matsushiga, Subaru Telescopeʻs Lucio Ramos, and Geminiʻs Jason Kalawe. Panelists shared how they got involved in working for the observatories and the path they took to get there. The panel included a wide range of careers: astronomers, engineers, human resources, web architects, and more. Students learned that having a PhD in astronomy isnʻt a requirement to working at an observatory, and in fact, astronomers only make up around 20% of an observatoryʻs staff.

Classroom Visits – Thursday, March 16th

We followed Scot Kleinman and Sylvia Kowalski to Keaukaha Elementary School. Kleinman received his PhD from the University of Texas in 1995. Currently, he is the Associate Director of Development at Gemini North, where he helps bring and develop the next generation of instruments to Gemini. Kowalski is the current Public Information and Outreach Intern at Gemini North. She graduated from the University of Washington with degrees in Physics, Astronomy, and Drama.

Kleinman taught the kids how to program and they got to simulate programming the movement of the Mars Rover.

Kleinman explained how Mission Control “talks” to the Mars Rover and tells it what to do.

Kowalski (left) played the Mars Rover and the students told Kowalski what to do and where to move.

Students attempt to prevent Kowalski from bumping into their desks.

Classroom Visits – Wednesday, March 15th

Yvonne Pendleton and Jennifer Baer of NASA SSERVI visited Kapiolani Elementary School. Pendleton obtained her PhD in astrophysics from the University of California at Santa Cruz and is currently the Director of NASA SSERVI. Baer is a graphic designer at NASA SSERVI and regularly works with scientists and engineers to take complex data and turn it into easily digestible media.

Students at Kapiolani Elementary were surprised and excited that NASA had graphic designers like Jennifer Baer!

Baer shows students that they can edit pictures with available software.

Students practice editing pictures on a tablet.

Discover, New Frontiers, and Solar System Exploration

Wednesday evening, NASA’s Brian Mitchell gave a talk at the University of Hawaiʻi at Hilo about NASA’s current and future vision for planetary exploration. Mitchell has more than 25 years at the Marshall Space Flight Center and has worked on various Space Shuttle payload missions including ASTRO, ATLAS, and Spacelab, as well as several experiments for the International Space Station. Mitchell is currently the Education and Public Outreach manager for NASA’s Discovery/New Frontiers/Lunar Quest Program Office, where he is tasked with communicating Planetary Missions Program Office science goals and objectives to the public in order to promote Science, Technology, Engineering, and Mathematics (STEM) participation.

Mitchell talked about the past and present NASA spacecrafts and the science they were doing at the University of Hawaiʻi at Hilo.

Classroom Visits – Tuesday, March 14th

Today we followed Tomonori Usuda to Hilo Intermediate School. Usuda earned his PhD in Astronomy at the University of Tokyo and is an optical-infrared astronomer for the National Astronomical Observatory of Japan. He currently leads the Thirty Meter Telescope (TMT) project as the director of TMT-Japan. Previously, he was the associate Director of Subaru Telescope from 2006-2013.

Tomonori Usuda traces the path the light travels to get to the instruments on Subaru Telescope.

Usuda explains the process behind changing out the instruments on the telescope.

Students recognized the brand name Mitsubishi, but they werenʻt aware that they designed some of the robotics used by Subaru!

Astronomy Educatorʻs Reception at the Naniloa

The Hawaiʻi Island Chamber of Commerce (HICC) and the Japanese Chamber of Commerce and Industry of Hawaiʻi (JCCIH) hosted a welcome celebration for the astronomy community, the Department of Education and the business community. Superintendents from the Hilo-Waiākea Complex, Kaʻū-Keaʻau-Pāhoa Complex, and representatives from the Honokaʻa-Kealakehe-Kohala-Konawaena Complex also attended the event. Guest speakers included: Janice Harvey, Journey Team Leader, Mayor Harry Kim, Gemini Director Markus Kissler-Patig, and PhD candidate and Hilo native Devin Chu. Chu shared his experiences in astronomy and how the Journey program influenced and helped guide his dream of becoming an astronomer.

Classroom Visits – Monday, March 13th

Our Public Information and Outreach department followed Devin Chu to Hilo Intermediate School and Teague Soderman to Kaumana Elementary School. Chu was born and raised in Hilo, Hawaiʻi and graduated from Hilo High School in 2010, where he was an ongoing participant in the Journey Through the Universe program He received his Bachelorʻs in Physics and Astronomy from Dartmouth in 2014, and his Masterʻs of Science in Astronomy from UCLA in 2016. He is currently working towards his PhD at UCLA while working under Andrea Ghez.

PhD candidate and Hilo native Devin Chu went back to Hilo Intermediate to talk to students about gravity.

Chu demonstrated how celestial objects move using a “gravity well,” a simulation of a point of strong gravitational pull.

Soderman, who currently works at NASAʻs SSERVI, is a science writer with a background in creative writing and graphic design. He received his Masterʻs in English and Creative Writing from San Francisco State Univesity, and has been writing for the scientific community for over 13 years.

Teague Soderman from NASA SSERVI showed Kaumana students some of the technology that NASA has sent to space.

Kaumana students and their teachers look at the Sun through special lenses that protect their eyes.

Soderman showed some of the mapping software available online through NASA SSERVI.

NASA Lunar and Meteorite Sample Certification Workshop

On Saturday, March 11th, Brian Day and Joseph Minafra, both from NASA SSERVI, held a workshop that certifies teachers to borrow lunar and meteorite samples from the historic Apollo missions. Teachers attending this workshop will also learn how to use NASA online tools to explore and visualize the surfaces of the Moon, asteroids, and Mars as seen through the eyes of many different instruments aboard a great range of spacecrafts.

NASA SSERVI’s Brian Day (six from the left) and Joseph Minafra (four from the left) led 10 teachers through a workshop that certifies them to borrow lunar and meteorite samples as teaching tools.

Brian (left) explains how these samples may be used in the classroom.

Educators had plenty of time during the all day workshop to examine the samples.

The samples provided contained lunar rocks harvested from the historic Apollo missions.

One teacher holds up the sample plate for a better look.

Exploring the StarLab Moon Cylinder

On Thursday, March 9th, Gemini staff and NASA SSERVIʻs Brian Day explored Geminiʻs newly acquired Moon Cylinder before Day held a StarLab presentation for the after school group Perpetuating Unique Educational Opportunities (PUEO). Day currently acts as SSERVIʻs project manager for NASAʻs Lunar Mapping and Modeling Portal, which is a set of tools designed for mission planning, lunar science, and public outreach. Students learned about geological features and phases of the Moon, as well as past and current NASA Moon missions.

The projection of the Moon in the StarLab maps beautiful features like Moon craters and mare.
