Globular Clusters in the Galaxy Cluster MACS0416 at z = 0.397
Abstract
We present a photometric analysis of globular clusters (GCs) in the massive galaxy cluster MACS J0416.1−2403 (z = 0.397) using deep JWST/NIRCam imaging from the PEARLS program. Point-spread function photometry was performed in the short wavelength filters, F090W, F115W, F150W, and F200W, yielding a catalog of ∼3 × 103 unresolved, point-like sources consistent with a GC population. Artificial-star tests indicate 80% completeness at F200W ≃ 30.36 …
