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…

PEARLS: Near Infrared Photometry in the JWST North Ecliptic Pole Time Domain Field

Christopher N. A. Willmer, Chun Ly, Satoshi Kikuta +23

We present Near-Infrared (NIR) ground-based Y, J, H, and K imaging obtained in the James Webb Space Telescope North Ecliptic Pole Time Domain Field (TDF) using the MMT-Magellan Inf…

A search for high-redshift direct-collapse black hole candidates in the PEARLS north ecliptic pole field

Armin Nabizadeh, Erik Zackrisson, Fabio Pacucci +31

Direct-collapse black holes (DCBHs) of mass - that form in HI-cooling halos in the early Universe are promising progenitors of the $\gtrsim 10^9 {M}_\odo…

Hidden giants in JWST's PEARLS: An ultra-massive z=4.26 sub-millimeter galaxy that is invisible to HST

Ian Smail, Ugne Dudzeviciute, Mark Gurwell +32

We present a multi-wavelength analysis using SMA, JCMT, NOEMA, JWST, HST, and SST of two dusty strongly star-forming galaxies, 850.1 and 850.2, seen through the massive cluster len…

Spectroscopy of the Supernova H0pe Host Galaxy at Redshift 1.78

M. Polletta, M. Nonino, B. Frye +42

Supernova (SN) H0pe was discovered as a new transient in James Webb Space Telescope (JWST) NIRCam images of the galaxy cluster PLCK G165.7+67.0 taken as part of the "Prime Extragal…

Powerful Radio-Loud Quasars are Triggered by Galaxy Mergers in the Cosmic Bright Ages

Peter Breiding, Marco Chiaberge, Erini Lambrides +14

While supermassive black holes are ubiquitous features of galactic nuclei, only a small minority are observed during episodes of luminous accretion. The physical mechanism(s) drivi…
