HI Properties of Low Surface Brightness Galaxies - Completing the Survey

Abstract

Although Low Surface Brightness (LSB) galaxies - objects with a central surface brightness at least one magnitude/sq. arcsec fainter than the night sky - are increasing well studied, considerable uncertainty still exists as to both the LSB galaxy properties and evolutionary history. Low surface brightness galaxies provide a fascinating extreme in galaxy formation and evolution and are excellent tests of galaxy formation and evolution theories. Our group has successfully used the GBT to determine the gas and dynamical mass properties of LSB galaxies, significantly increasing the number of extreme LSB galaxies (massive, gas rich, etc) in the process. Here we propose to complete observation of UGC galaxies that were original observed as part of GBT24B-415 but which did not reach the desired sensitivity due to RFI issues.
