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…

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…

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…

PEARLS: Discovery of Point-Source Features Within Galaxies in the North Ecliptic Pole Time Domain Field

Rafael Ortiz, Rogier A. Windhorst, Seth H. Cohen +36

The first public 0.9-4.4μm NIRCam images of the North Ecliptic Pole (NEP) Time Domain Field (TDF) uncovered galaxies displaying point-source features in their cores as seen in the…

TREASUREHUNT: Transients and Variability Discovered with HST in the JWST North Ecliptic Pole Time Domain Field

Rosalia O'Brien, Rolf A. Jansen, Norman A. Grogin +56

The JWST North Ecliptic Pole (NEP) Time Domain Field (TDF) is a 14 arcmin diameter field optimized for multi-wavelength time-domain science with JWST. It has been observed acros…

PEARLS: JWST counterparts of micro-Jy radio sources in the Time Domain Field

S. P. Willner, H. B. Gim, M. del Carmen Polletta +38

The Time Domain Field (TDF) near the North Ecliptic Pole in JWST's continuous-viewing zone will become a premier "blank field" for extragalactic science. JWST/NIRCam data in a 16 a…
