GALEX Arecibo SDSS Survey

(HI survey of many galaxies)

The GALEX Arecibo SDSS Survey (GASS) is a survey if HI and H2 Emissions from over a thousand galaxies. Galaxies were chosen from Sloan Digital Sky Survey (SDSS) and Galaxy Evolution Explorer (GALEX) so that cross correlations can be made. Observations were made in 2008-2009 at Arecibo Observatory (NAIC), using the 21cm Line to detect HI. Three data releases have followed, the first in 2010.
