Abstract

Supernovae (SNe) play a critical role in the metal enrichment of the intracluster medium (ICM) in galaxy clusters. Not only are SNe the main source for metals, but they may also supply the energy to eject enriched gas from galaxies by winds. However, measurements of SN rates in galaxy clusters have not been published to date. The authors have initiated a program to find SNe in 163 medium-redshift (0.06<z<0.2) Abell clusters, using the Wise Observatory 1m telescope. They report on their first results and describe their main scientific goals. Following the discovery of a SN in the remote periphery (78 Kpc) of the cD galaxy of Abell 403, they discuss a novel explanation for the centrally enhanced metal abundances indicated by X-ray observations of galaxy clusters.
