Gemini Frontier Fields

September 11th, 2014

The Gemini Frontier Fields campaign targets three of the Frontier Fields with GeMS/GSAOI. We obtain high-resolution Ks-band imaging with an exposure time of about 5.2h per cluster, complementing the HST/WFC3 data redwards of their 1.7μm cut-off. Given the scarcity of natural guide stars, both PSF FWHM and variations increase with growing angular separation from the guide star. The average GSAOI FWHM is about twice as high as HST/WFC3's in its F160W (H-band) filter.
