The GALEX Arecibo SDSS Survey (GASS) is an ongoing large targeted survey at Arecibo, home to the world's largest single-dish radio telescope. GASS is designed to measure the neutral hydrogen content of a representative sample of ~1000 massive galaxies, uniformly selected from the SDSS spectroscopic and GALEX imaging surveys. A sister survey COLD GASS is being conducted at the IRAM 30m telescope to better understand the connection between atomic and molecular gas and star formation in the same galaxies.
I will discuss recent results from both surveys, highlighting how how the outer disks of spiral galaxies like our own Milky Way are still being assembled at the present day. |
