Abstract:
The galaxy environment is essential to the formation and growth of galaxies and their central supermassive black holes. We propose three ACIS-I pointings to over ~80 early-type galaxies in Antlia, the nearest non-cool-core and the nearest merging galaxy cluster. Antlia provides a unique environment to study the nuclear activity that cannot be achieved in any other cluster. Most importantly, as a newly-formed and dynamically young cluster, it is the closest analog to the high redshift Universe. We expect higher SMBH activity in Antlia than in Virgo due to its large population of gas-rich galaxies. Its SMBH activity may be even higher than the field as ram pressure may compress gas towards the nuclei to trigger AGN before quenching.

Remarks:
Requesting target name change from LEDA 83120 to Antlia Cluster SE
