Gemini Planet Imager (GPI): Cleared for Shipment to Gemini South!

In a milestone statement distributed moments ago by the GPI Pre-delivery Acceptance Review Committee, Chair Stephen Goodsell announced that GPI is now clear for shipment from the University of California Santa Cruz to Gemini South in Chile.The Committee’s final report is slated for release on July 26th, but a statement sumarizing the results of the review is available now - GPI Review Committee: Final Day Statement  41 KB

Cancelation of the November GeMS run

The GeMS / GSAOI laser run that was planned to take place this week had to be canceled. Unfortunately the laser and the Canopus Real Time Control system were not operational and in spite of intense efforts to resolve these problems in time for the laser window there was just not sufficient time to get the system in an operational state. We will continue to work towards ensuring that the upcoming January GeMS / GSAOI run will be a success.

Gemini Characterizes Cheshire Cat

Gemini spectroscopy provided critical spectroscopic data for characterizing the foreground lensing cluster and understanding its history and likely fate as a "fossil group."

Gemini Instrument Feasibility Study (GIFS) reports available.

Gemini Observatory is pleased to announce the release of the public GIFS reports.

OCTOCAM Feasibility Study


The OCTOCAM study was led by Antonio de Ugarte Postigo and managed by Pete Roming and Christina Thöne. The project was coordinated from the Instituto de Astrofisica de Andalucia (IAA-CSIC), with main collaborators at the Southwest Research Institute, Fractal SLNE, and George Washington University. The study began in April 2015 and concluded in October 2015.

Gemini Planet Imager Exoplanet Survey – One Year into the Survey

Orbital motion of 51 Eri b detected between two H-band observations taken with the Gemini Planet Imager in December 2014 and September 2015. From this motion, and additional observations of the system, the team of astronomers confirmed that this point of light below the star is indeed a planet orbiting 51 Eri and not a brown dwarf passing along our line of sight.

GPI OT Details

This page describes the steps to properly configure the instrument using the OT. Generally the user should use the skeleton templates that are created in Phase II and apply them to obtain the proper sequences. Instructions on for the general use of the OT can be found on the OT page and related links, as this page describes particular details for using OT with GPI. 

The GPI in the OT can be broken down into the following components: 

Illumination of the Early Universe by Quasars: Korea's 1st Result as Limited Gemini Partner

Figure 1. Color composite-image of IMS J2204+0111 at z=6 (about 1 billion years after the Big Bang). IMS J2204+0111 is the red object at the center and its distance from us is 12.8 billion light years. Because of the expansion of the universe, distant objects like IMS J2204+0111 move away from us almost at the speed of the light, making their light to shift into near-infrared wavelength (phenomenon, called “redshift”).
