Gemini Featured at Extreme Solar Systems III Conference

Observations using the Gemini Planet Imager are featured prominently at the Extreme Solar Systems III meeting ongoing this week (Nov. 29 - December 4) in Waikoloa Hawai‘i. Below are two results from a press conference on December 1, 2015.

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.

National Gemini Offices

Gemini is operated by a partnership of the United States, Canada, Chile, Brazil, and Argentina. These Participants and the University of Hawaii, which has regular access to Gemini, each maintain a “National Gemini Office” to support their local users.

OCTOCAM Feasibility Study

Introduction

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.

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. There is a GS-GPI-library available that contains complete examples of various modes and setups. Use the OT and select "libraries" and the program can be downloaded. 

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”).

Limiting magnitudes for instrument and internal wavefront sensors

GPI limiting magnitudes are determined by several components, the AO WFS (I-band), the LOWFS (H-band), and the IFS (selected filter). In addition the observing conditions add another layer of limits. Thus the brightest of the science object is limited in I band from the AOWFS, in H-band from the LOWFS (not a constraint in DIRECT mode as then no coronographic mask is used and no LOWFS is possible). It should be noted that it is NOT possible to observe without the AOWFS and Coronographic modes are NOT possible to observe without the LOWFS.
