Proposal Title: The Spatial Distribution of LSBs in the Pisces-Perseus Supercluster
ABSTRACT:
Low Surface Brightness galaxies (LSBs) appear to be the remnants of the lowest density fragments of the initial
density perturbation spectrum of the early Universe (Impey and Bothun 1997). As such, LSBs should be isolated
on small scales but otherwise they should trace out the same mass distribution seen in luminous \normal" high
surface brightness galaxies. In fact, such traits have been observed for LSBs. However, these results are based on
studies of several hundred LSBs scattered over the entire sky. We propose to instead construct a catalog with the
spatial positions (and HI content) of roughly 60 LSBs over a smaller eld covering the Pisces-Perseus Supercluster.
This supercluster is one of the most well-studied nearby superclusters and as such we can leverage previous
observations with our new LSB observations to gain a better understanding of the environment in which LSBs
reside, which may have signicant implications for galaxy evolution in general.
