A cool core remnant in one of the brightest non-cool core clusters?
Abstract
Chandra data have been the key to establish the bimodality in cluster cores and the relationship between radio AGN and X-ray cool cores. The transition between cool cores and non-cool cores is still an outstanding question. Strong radio AGN heating may produce cool core remnants, as suggested by some previous work. We have started a Chandra project to study cool core remnants with central abundance excess. In this proposal, we request 80 ks observations on the closest cool core remnant in the 3C129.1 cluster, also one of the brightest non-cool core clusters in the sky. We will study the heated core with an elevated abundance in detail, examine the central corona and the candidates of ultraluminous X-ray sources in 3C129.1. The results will provide a benchmark for cool core remnants.
