Correlations in Relaxed Clusters of Galaxies

Open Astronomy, 2014
The correlations among different quantities in galaxy clusters, observed by Newman et al. (2013a,b), are investigated. We find an anti-correlation among the slope α, the effective radius, Re, and a correlation among the core radius rcore and Re. Moreover,

Star Formation, Nebulae, and Active Galactic Nuclei in CLASH Brightest Cluster Galaxies. I. Dependence on Core Entropy of Intracluster Medium

The Astrophysical Journal
We set the stage for reassessing how star formation, emission-line nebulae, and active galactic nuclei (AGNs) in brightest cluster galaxies (BCGs) depend on the thermodynamics of the intracluster medium (ICM).

Selecting Clusters and Protoclusters via Stellar Mass Density. II. Application to HSC-SSP Observations

The Astrophysical Journal
We present a selection of candidates of clusters and protoclusters of galaxies identified in the photometric data of the HSC-SSP Wide Public Data Release 3 (PDR3), spanning the redshift range 0.1 ≤ z ≤ 2. The selection method, detailed in Vicentin et al.,

Detection of Compton Scattering in the Jet of 3C 84

The Astrophysical Journal Letters
3C 84 is the brightest cluster galaxy in the Perseus Cluster. It is among the closest radio-loud active galaxies and among the very few that can be detected from low-frequency radio up to TeV γ -rays.

JWST Photometry of Globular Cluster Populations in MACS0417.5−1154

The Astrophysical Journal
Deep JWST imaging of the massive galaxy cluster MACS0417.5−1154, at redshift z = 0.443, reveals a huge population of globular clusters (GCs) and ultracompact dwarfs (UCDs) primarily distributed around its single central giant brightest cluster galaxy ...
