Figure 1. Color composite image of the central region of NGC 253, from Flamingos 2 images using the filters J (blue), H (green) and Ks (red). This region of the edge-on viewed galaxy appears completely veiled in optical images due to the presence of large amounts of dust (so dense that it is still obscuring some regions at the near-infrared spectral range). The wavelength range covered by F-2 goes from 1 to 2.5 μm. The field of view is 420 x 144 arcseconds.

Gemini is seeking to upgrade its operational instruments to keep them scientifically competitive. Gemini’s development program will provide funding to upgrade existing operational instrumentation, creating new instrument capabilities at the Gemini North and/or South telescopes. The Observatory is seeking community-created, science-driven instrumentation upgrade proposals, and will consider any area that fits the set of IUSP requirements provide in the RFP.
AURA is seeking to replace the current continuous wave (CW) mode-locked 50 Watt laser at the Gemini South facility with a more robust alternative Laser (the subject of this RFQ, hereafter called the “Laser”) providing a photon return equivalent to or greater than currently received by its 5 laser guide star Multi-Conjugate Adaptive Optics system, GeMS.
Gemini North and South are accepting proposals for the Fast Turnaround (FT) pilot 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.
Left: (Ks, F606W-Ks) color–magnitude diagram of NGC 1851; the detail of the double SGB is shown in the inset. Right: same as the left panel with average photometric (random) uncertainties indicated. Overlaid is the fiducial line with the approximate locations of the main sequence turnoff and main sequence knee highlighted by red dots.
The Gemini-S telescope survived an 8.4 magnitude earthquake the previous week. Following an intense week of detailed inspections and testing of the infrastructure, the telescope, and the instruments were released for normal use. During the inspection some components were found broken or displaced, but all could be repaired and adjusted and no major damage was sustained.
On-sky tests over the weekend showed that all is well and science observations have resumed.
On September 16th, 2015, La Serena was hit by a magnitude ~8.3 earthquake at 19:54 local time, with the epicenter about 150 km from La Serena. Fortunately, Gemini staff at the Cerro Pachón summit and in La Serena were all fine. Our thoughts go out to the people that lost their lives and homes due to the quake and the following tsunami that strongly impacted the coastal areas.
