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…

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…

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…

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…
