Proposal Title: HI Observations of Gas Poor Galaxies from the Sloan Digital Sky Survey
ABSTRACT:
We propose to make HI observations of 131 optically selected, nearby (cz <3000 km/s) galaxies from the Sloan
Digital Sky Survey (SDSS). These objects are all objects that fall within the HI Parkes All Sky Survey (HIPASS)
and yet have no detectable HI emission. Many of these galaxies have optical spectra that suggest active star
formation is occurring and therefore should have some observable HI. Our proposed plan is to use the Arecibo
305m telescope to improve upon the sensitivity of HIPASS by a factor of ten. This will allow us to probe HI masses
ten times smaller than were possible in HIPASS and resolve the apparent issue that there are actively star forming
galaxies without detectable HI.
