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

open access: yesThe 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 ...

A distinct radial acceleration relation across the brightest cluster galaxies and galaxy clusters

open access: yesAstronomy & Astrophysics
Recent studies reveal a radial acceleration relation (RAR) in galaxies, which illustrates a tight empirical correlation connecting the observational acceleration and the baryonic acceleration with a characteristic acceleration scale. However, a distinct RAR has been revealed on brightest cluster galaxy (BCG) cluster scales with a seventeen-times-larger

A Multiwavelength Approach to Constraining the Merger Properties of ACT-CL J0034.4+0225

open access: yesThe Astrophysical Journal
ACT-CL J0034.4+0225 is a previously unrecognized merging galaxy cluster at z = 0.38588 ± 0.00068. Our primary evidence is provided by a 21 ks Chandra image that shows two surface brightness peaks separated by ∼49″ (259 kpc) surrounded by an extended ...

Using Neural Networks to Automate the Identification of Brightest Cluster Galaxies in Large Surveys

open access: yesThe Astrophysical Journal
Brightest cluster galaxies (BCGs) lie deep within the largest gravitationally bound structures in existence. Though some cluster finding techniques identify the position of the BCG and use it as the cluster center, other techniques may not automatically ...
