The Sphere of Influence of the Bright Central Galaxies in the Diffuse Light of SDSS Clusters
Xiaokai Chen, Ying Zu, Zhiwei Shao +1
The bright central galaxies (BCGs) dominate the inner portion of the diffuse cluster light, but it is still unclear where the intracluster light (ICL) takes over. To investigate th…
Strong Conformity and Assembly Bias: Towards a Physical Understanding of the Galaxy-Halo Connection in SDSS Clusters
Ying Zu, Yunjia Song, Zhiwei Shao +6
Understanding the physical connection between cluster galaxies and massive haloes is key to mitigating systematic uncertainties in next-generation cluster cosmology. We develop a n…
AGN STORM 2: I. First results: A Change in the Weather of Mrk 817
Erin Kara, Missagh Mehdipour, Gerard A. Kriss +69
We present the first results from the ongoing, intensive, multi-wavelength monitoring program of the luminous Seyfert 1 galaxy Mrk 817. While this AGN was, in part, selected for it…
Kinematics of MgII Absorbers from the Redshift-space Distortion Around Massive Quiescent Galaxies
Ying Zu
The kinematics of MgII absorbers is the key to understanding the origin of cool, metal-enriched gas clouds in the circumgalactic medium of massive quiescent galaxies. Exploiting th…
