Title: Probing Star Formation in Cluster Galaxies using Deep U-band Imaging

Abstract: We propose to obtain deep $U$-band observations of nine low-redshift galaxy clusters ($0.02 < z < 0.06$) using the WIYN 0.9m+HDI telescope/detector to map star formation from giant to dwarf galaxy systems in high-density cluster environments. Our cluster targets are selected from a sample of 57 clusters in which we have previously obtained deep $B$- and $R$-band data from the KPNO 0.9m+MOSA. The addition of deep $U$-band data will allow us to explore relative changes in the luminosity function for the $U$- and $R$-band as a function of cluster-centric radius for a statistically significant sample. The large field-of-view of the telescope+detector will permit us to map out the spatial distribution of star forming galaxies from the core region to the cluster outskirts. The comparison of $U$-band observations with our $R$-band data will provide the necessary leverage to look for enhancements/quenching of star formation as galaxies fall into the cluster environment. These observations will allow us to probe to fainter $U$-band magnitudes than SDSS, thus helping to unveil star formation from giant to dwarf galaxies.
