2016B Call for Proposals Announced

Gemini is now accepting proposals for observing time in Semester 2016B. The submission deadline varies with partner. A new version of the Phase I Tool (PIT) has been released to support proposal submissions.

Supermassive Black Hole - That Wasn't

Figure 1. GMOS-South image of the center of the Abell 85 galaxy cluster. The brightest galaxy in the middle was thought to hide a supermassive black hole in its core based on prior lower-resolution data.

Are the Coolest Brown Dwarfs Loners?

 

Figure 1.  Left: Y dwarfs imaged in the CH4S filter. For each object two panels are shown, with the left displaying a 0.8×0.8 arcsecond sub-image centered on the Y dwarf, and the right showing a nearby reference star. All images are north up and east to the left.

 

Download data from the Gemini Observatory Archive (GOA)

Since November 2015, all science data and the associated calibrations are stored in, and accessed via, the Gemini Observatory Archive (GOA), which is operated by the Observatory. All Gemini data has been transferred into the new archive and can be accessible from the GOA. The GOA is described here. Detailed instructions to search and retrieve science data and associated calibrations are given in the GOA Help web page.

Gemini Confirms a Free-Floating Planet

Our observed spectrum of PSO J318.5−22 (black) compared to the forward model with our best fit parameters (red). The median residual of the fit is 0.079 (in normalized Fλ units), which is larger than the median uncertainty (0.048) of our observed spectrum. The rms of the residuals (0.12) indicates systematic uncertainties of ≈10%.

PWFS2 (non-siderial targets)

The PWFS2 is available for observing non-siderial targets or when a suitable OIWFS star is not available. There are a few drawbacks with using the P2WFS instead of the OIWFS which are:

 

  • The flexure between the probe arm and the detector has not been quantified

February Call for Proposals

Gemini North and South are accepting proposals for the Fast Turnaround (FT) program. Here, we give information specific to this proposal cycle. Please see the other FT pages - particularly the rules - for general information about the program. Users should be aware that FT-specific proposal templates must now be used for all FT proposals; see the "PIT information" section below.
