PEARLS: NuSTAR and XMM-Newton Extragalactic Survey of the JWST North Ecliptic Pole Time-domain Field III
Ross Silver, Francesca Civano, Xiurui Zhao +28
The James Webb Space Telescope (JWST) North Ecliptic Pole (NEP) Time-Domain Field (TDF) has been monitored by NuSTAR and XMM-Newton with a regular cadence for five years starting i…
SKYSURF VIII -- Modeling SKYSURF Completeness Data for Comparison to the Hubble Space Telescope Exposure Time Calculator
Zachary Goisman, Timothy Carleton, Seth H. Cohen +4
Accurately assessing image source completeness is critical for interpreting measurements on telescope data. Using the Wide Field Camera 3 (WFC3) and Advanced Camera for Surveys (AC…
SKYSURF IX -- The Cosmic Optical and Infrared Background from Integrated Galaxy Light Measurements
Scott A. Tompkins, Simon P. Driver, Aaron S. G. Robotham +15
As part of the SKYSURF Hubble Space Telescope (HST) Legacy Archival program we present galaxy number counts which yield measurements of the extragalactic background light (EBL) at…
PEARLS: 21 Transients Found in the Three-Epoch NIRCam Observations in the Continuous Viewing Zone of the James Webb Space Telescope
Haojing Yan, Bangzheng Sun, Zhiyuan Ma +39
We present 21 transients from our three-epoch, four-band NIRCam observations covering 14.16 arcmin^2 in the Spitzer IRAC Dark Field (IDF), taken by the JWST Prime Extragalactic Are…
Lonely Little Red Dots: Challenges to the AGN-nature of little red dots through their clustering and spectral energy distributions
María Carranza-Escudero, Christopher J. Conselice, Nathan Adams +31
Observations with the James Webb Space Telescope (JWST) reveal a previously unseen population of compact red objects, known as ``little red dots`` (LRDs). We study a new photometri…
Stellar Populations and Molecular Gas Composition in the Low-Metallicity Environment of WLM
Haylee N. Archer, Deidre A. Hunter, Bruce G. Elmegreen +8
We investigate the stellar populations and molecular gas properties of a star-forming region within the dwarf irregular (dIrr) galaxy WLM. Low-metallicity dIrrs like WLM offer a va…
