Spectral Energy Distributions of Globular Clusters in VV191a
Ashton Cardona, Timothy Carleton, Jessica Berkheimer +9
We investigate globular cluster (GC) candidates associated with the elliptical galaxy VV191a using JWST NIRCam and archival HST imaging. Beginning with an initial catalog of over 5…
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…
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…
Birds of a Feather: Resolving Stellar Mass Assembly With JWST/NIRCam in a Pair of Kindred Dusty Star-forming Galaxies Lensed by the PLCK G165.7+67.0 Cluster
Patrick S. Kamieneski, Brenda L. Frye, Rogier A. Windhorst +38
We present a new parametric lens model for the G165.7+67.0 galaxy cluster, which was discovered with through its bright submillimeter flux, originating from a pair of extr…
