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…

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…

The Distribution of Quenched Galaxies in the Massive z = 0.87 Galaxy Cluster El Gordo

Rachel Honor, Seth Cohen, Timothy Carleton +27

El Gordo (ACT-CL J01024915) is a massive galaxy cluster with two major mass components at redshift . Using SED fitting results from JWST/NIRCam photometry, the fraction…
