The Roman eXtreme Deep Field (RXDF)
Haojing Yan, Anton M. Koekemoer, Yue Shen +127
The Roman eXtreme Deep Field (RXDF) program is one of the five General Astrophysics Survey (GAS) programs approved for observing time with the Nancy Grace Roman Space Telescope in…
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…
SKYSURF. X. A Novel Method for Measuring Integrated Galaxy Light
Delondrae D. Carter, Timothy Carleton, Daniel J. Henningsen +19
We describe the drizzling pipeline and contents of the drizzled database for Hubble Space Telescope Cycle 27-29 Archival Legacy project "SKYSURF," the largest archival project ever…
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…
Ground- and Space-Based Dust Observations of VV 191 Overlapping Galaxy Pair
C. Robertson, B. Holwerda, J. Young +12
The Balmer decrement (H/H) provides a constraint on attenuation, the cumulative effects of dust grains in the ISM. The ratio is a reliable spectroscopic tool for deriving the…
JWST's PEARLS: 119 multiply imaged galaxies behind MACS0416, lensing properties of caustic crossing galaxies, and the relation between halo mass and number of globular clusters at
Jose M. Diego, Nathan J. Adams, Steven Willner +26
We present a new lens model for the galaxy cluster MACS J0416.12403 based on a previously known set of 77 spectroscopically confirmed, multiply imaged galaxies plus an…
JWST NIRCam Photometry: A Study of Globular Clusters Surrounding Bright Elliptical Galaxy VV 191a at z=0.0513
Jessica M. Berkheimer, Timothy Carleton, Rogier A. Windhorst +22
James Webb Space Telescope NIRCam images have revealed 154 reliable globular cluster (GC) candidates around the elliptical galaxy VV~191a after subtracting 34 likely i…
SKYSURF-4: Panchromatic HST All-Sky Surface-Brightness Measurement Methods and Results
Rosalia O'Brien, Timothy Carleton, Rogier A. Windhorst +22
The diffuse, unresolved sky provides most of the photons that the Hubble Space Telescope (HST) receives, yet remains poorly understood. HST Archival Legacy program SKYSURF aims to…
SKYSURF: Constraints on Zodiacal Light and Extragalactic Background Light through Panchromatic HST All-Sky Surface-Brightness Measurements: II. First Limits on Diffuse Light at 1.25, 1.4, and 1.6 microns
Timothy Carleton, Rogier A. Windhorst, Rosalia O'Brien +28
We present the first results from the HST Archival Legacy project "SKYSURF." As described in Windhorst et al. 2022, SKYSURF utilizes the large HST archive to study the diffuse UV,…
SKYSURF: Constraints on Zodiacal Light and Extragalactic Background Light through Panchromatic HST All-Sky Surface-Brightness Measurements: I. Survey Overview and Methods
Rogier A. Windhorst, Timothy Carleton, Rosalia O'Brien +35
We give an overview and describe the rationale, methods, and testing of the Hubble Space Telescope (HST) Archival Legacy project "SKYSURF." SKYSURF uses HST's unique capability as…
