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…
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…
A long time ago in an LAE far, far away: a signpost of early reionization or a nascent AGN at ?
Joshua Cohon, Christopher Cain, Rogier Windhorst +3
The JADES survey recently reported the discovery of JADES-GS-z13-1-LA at , the highest redshift Ly emitter (LAE) ever observed. This observation suggests that either th…
