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: JWST Counterparts of Micro-Jy Radio Sources in the NEP Time Domain Field. II. All Four Spokes
S. P. Willner, Hansung B. Gim, Maria del Carmen Polletta +18
JWST/NIRCam observations in the North Ecliptic Pole Time Domain Field (TDF) identify 4.4 micron counterparts for 206 of 211 radio sources with S(3 GHz) \gapprox 5 micro-Jy in a 65a…
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…

We present 5 GHz e-MERLIN radio images at 50 mas resolution of the nuclear regions of the Legacy e-MERLIN Multi-band Imaging of Nearby Galaxies survey (LeMMINGs), the deepest stati…
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…
JWST's PEARLS: A Candidate Massive Binary Star System in a Lensed Galaxy at Redshift 0.94
Hayley Williams, Patrick L. Kelly, Emmanouil Zapartas +18
Massive stars at cosmological distances can be individually detected during transient microlensing events, when gravitational lensing magnifications may exceed ~1000. Nine such sou…
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…
RGC-Bent: A Novel Dataset for Bent Radio Galaxy Classification
Mir Sazzat Hossain, Khan Muhammad Bin Asad, Payaswini Saikia +7
We introduce a novel machine learning dataset tailored for the classification of bent radio active galactic nuclei (AGN) in astronomical observations. Bent radio AGN, distinguished…
JWSTs PEARLS: NIRCam imaging and NIRISS spectroscopy of a star-forming galaxy lensed into a near-Einstein Ring by a massive elliptical galaxy

We present the discovery, and initial lensing analysis, of a high-redshift galaxy-galaxy lensing system within the JWST-PEARLS/HST-TREASUREHUNT North Ecliptic Pole Time Domain Fiel…
LeMMINGs. Multi-wavelength constraints on the co-existence of nuclear star clusters and AGN in nucleated galaxies
B. T. Dullo, J. H. Knapen, R. D. Baldi +16
[Abridged] The relation between nuclear star clusters (NSCs) and the growth of the central SMBHs, as well as their connection to the properties of the host galaxies, is crucial for…
Evidence for low power radio jet-ISM interaction at 10 parsec in the dwarf AGN host NGC 4395
Payel Nandi, C. S. Stalin, D. J. Saikia +10
Black hole driven outflows in galaxies hosting active galactic nuclei (AGN) may interact with their interstellar medium (ISM) affecting star formation. Such feedback processes, rem…
