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: NuSTAR and XMM-Newton Extragalactic Survey of the JWST North Ecliptic Pole Time Domain Field VI: Multiwavelength SED Analysis
Rafael Ortiz, Francesca Civano, Rogier A. Windhorst +27
We model spectral energy distributions of 261 X-ray sources to in the North Ecliptic Pole Time Domain Field, extending prior XMM-Newton and NuSTAR analyses. Using the st…
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…
PEARLS: Two Distinct Populations of AGN Hosts Moving Between Star Formation and Quiescence
Gibson B. Bowling, Rafael Ortiz, S. P. Willner +29
We present the results of AGN--host-galaxy decomposition using JWST/NIRCam, HST/ACS, and HST/WFC3 imaging of the North Ecliptic Pole Time Domain Field (NEP-TDF). The light-profiles…
SKYSURF-11: A New Zodiacal Light Model Optimized for Optical Wavelengths
Rosalia O'Brien, Richard G. Arendt, Rogier A. Windhorst +15
We present an improved zodiacal light model, optimized for optical wavelengths, using archival Hubble Space Telescope (HST) imaging from the SKYSURF program. The Kelsall et al. 199…
Comparative Bayesian SED Fitting of PEARLSDG
BarıŠBayraktar, Timothy Carleton, Rogier A. Windhorst +2
The initial distance to PEARLSDG estimated from the Tip of the Red Giant Branch suggested it was an exotic isolated quiescent dwarf galaxy. We combine recent and archival Hectospec…
