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 ...

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.
