On the correlation between globular clusters and the distribution of dark matter in galaxy clusters: the case of Abell 2744
Marta Reina-Campos, Joshua S. Speagle, William E. Harris
Globular clusters (GCs) lie scattered around the inner of the virial radius of galaxy clusters, potentially being excellent tracers of the underlying mass distribution. In t…
Globular Clusters in the Galaxy Cluster MACS0416 at z = 0.397
Jessica M. Berkheimer, Rogier A. Windhorst, William E. Harris +27
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. PSF…
JWST Photometry of Globular Cluster Populations in MACS0417.5-1154
William E. Harris, Marta Reina-Campos, Kaitlyn E. Keatley +8
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 Ultra-Compact Dwarfs (UCDs) primarily…
PEARLS: Globular Clusters and Ultra-Compact Dwarfs in the El Gordo Galaxies at z=0.87
William E. Harris, Marta Reina-Campos, Anton M. Koekemoer +11
JWST/NIRCam 0.9 to 2.0 micron images reveal a population of point sources around the major galaxies in the El Gordo cluster at redshift z=0.87. Their distribution in the color--mag…
