Proposal Title: Continuation of a 21-cm Study of 127 Newly Discovered, Nearby LSB Galaxies
ABSTRACT:
We have discovered approximately 130 new low surface brightness galaxies believed to lie with in 3,000 - 8,000
km/s, including the rst known contingent of very red LSB galaxies. To determine the redshift and gas content of
these objects, we propose to continue 21-cm detection of these galaxies. Based on use of Arecibo during the June
`commissioning phase', we expect easy detection within 1-3 5 minute ON/OFF pairs for most galaxies.
