Environmental Sculpting of Galaxy Structure at Fixed Stellar Mass: A Multi-Scale Analysis Across Cosmic Time using 3 Million HSC Galaxies
Caitlin Igel, Aritra Ghosh, Andrew J. Connolly +4
The extent to which galaxy structure is shaped by environment beyond the local universe, once stellar mass is controlled, remains an open question in galaxy evolution. We address t…
A Splashback-like Feature of Central Galaxies in Galaxy Clusters
Yuanyuan Zhang, Susmita Adhikari, Louise O. V. Edwards +3
We investigate a splashback-like feature in the outer region of central galaxies (CGs) in clusters. This feature is detected as a "dip" in the radial slope of the CG surface bright…
The Megaparsec-scale Gas-sloshing Spiral in the Remnant Cool Core Cluster Abell 1763
E. M. Douglass, E. L. Blanton, S. W. Randall +4
We present a multiwavelength study of the massive galaxy cluster Abell 1763 at redshift z = 0.231. Image analysis of a 19.6 ks Chandra archival observation reveals a cluster-wide s…
Cold, clumpy accretion onto an active supermassive black hole
Grant R. Tremblay, J. B. Raymond Oonk, Françoise Combes +22
Supermassive black holes in galaxy centres can grow by the accretion of gas, liberating energy that might regulate star formation on galaxy-wide scales. The nature of the gaseous f…
