JWST Photometry of Globular Cluster Populations in MACS0417.5−1154
Abstract
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 (BCG). We present Near-Infrared Camera (NIRCam)/short-wavelength channel photometry of the GC system in four bands (F090W, F115W, F150W, and F200W). The spatial distribution of the system matches …
