Title: Uncovering Star Formation from the Galaxy Cluster Core to the Infall Region

Abstract: We propose to obtain deep $u$- and $r$-band observations of 40 low- redshift galaxy clusters ($zleq 0.03$) using the CTIO Blanco 4m+DECam telescope/detector in order to map star formation from the cluster core to the outskirt infall region. The deep $u$- and $r$-band data will allow us to explore relative changes in the luminosity function, dwarf- to-giant ratio, blue fraction, and galaxy morphological type as a function of cluster-centric radius for a statistically significant sample of clusters. The large field-of-view of the telescope+detector will permit us to not only map star formation out to the infall region, but also to probe dwarf galaxies using a reasonable exposure time due to the low redshift of our target sample. The comparison of $u$- and $r$- band observations will provide the necessary leverage to look for enhancements/quenching of star formation as galaxies fall into the cluster environment from the low density field region.
