HI巡天

HIPASS

• The HI Parkes All-Sky Survey (HIPASS) covered 30000 deg2 and produced a final catalog of around 5000 HI detections with a median redshift of 2800 km/s.

ALFALFA

• Arecibo Legacy Fast ALFA Survey (ALFALFA) will map 7000 deg2 and is expected to detect more than 25,000 extragalactic HI line sources out to redshifts of 18,000 km/s.

AGES

• Arecibo Galaxy Environment Survey (AGES), will cover a total area of 200 deg2 (divided into 13 predesignated regions to sample different environments) to greater depth

GASS

• GALEX Arecibo SDSS Survey (GASS), a sample of ~1000 galaxies (randomly selected within the footprint of SDSS spectroscopy, ALFALFA, and GALEX medium imaging survey) with stellar mass greater than 1010 Msun and gas mass fractions as low as 1.5%.

COLD GASS

• CO legacy Database for GASS
• 3666 galaxies randomly from GASS to form COLD GASS
• deep CO(1-0) imaging with IRAM
