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…

We Must Preserve Hubble given its Unique Complementarity to Webb, Roman, and Euclid

Rogier A. Windhorst, Gibson B. Bowling, Kevin S. Croker +17

We present compelling arguments -- focusing on galaxy science -- for preserving the main imagers and operational modes of the Hubble Space Telescope (HST) for as long as is technic…

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…
