Abstract:
We have begun a program to search for supernovae and other transients
in the fields of galaxy clusters with the 2.3m Bok Telescope on Kitt
Peak. We present our automated photometric methods for data reduction,
efficiency characterization, and initial spectroscopy. With this
program, we aim to ultimately identify ∼25-35 cluster Type Ia
supernovae (SNe Ia) (∼10 of which will be intracluster, hostless
events) and constrain the SN Ia rate associated with old, passive
stellar populations. With these measurements we will constrain the
relative contribution of hostless and hosted SNe Ia to the metal
enrichment of the intracluster medium.
Description:
The observations were conducted with the prime focus imager, 90Prime,
on the 2.3m Bok telescope on Kitt Peak.
