Extreme Ionizing Properties of Metal-Poor, Muv ~ -12 Star Complex in the first Gyr
E. Vanzella, F. Loiacono, M. Messa +38
We report the serendipitous discovery of a faint (M_UV > -12.2), low-metallicity (Z ~ 0.02 Zsun), ionizing source (dubbed T2c) with a spectroscopic redshift of z=6.146. T2c is part…
Anatomy of a z=6 Lyman-α emitter down to parsec scales: extreme UV slopes, metal-poor regions and possibly leaking star clusters

We present a detailed JWST/NIRSpec and NIRCam analysis of a gravitationally-lensed galaxy () at redshift 6.14 magnified by the Hubble Frontier Field galaxy cluster MAC…
JWST's PEARLS: resolved study of the stellar and dust components in starburst galaxies at cosmic noon
M. Polletta, B. L. Frye, N. Garuda +35
Dusty star-forming galaxies (DSFGs) contribute significantly to the stellar buildup at cosmic noon. Major mergers and gas accretion are often invoked to explain DSFGs' prodigious s…
A Lens Finder Map to check claimed High-z Galaxies behind SMACS J0723.3-7327

The first science image released by the JWST reveals numerous galaxies in the distant background of the galaxy cluster SMACS J0723.3-7327. Some have claimed redshifts of up to $z \…
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: A Potentially Isolated Quiescent Dwarf Galaxy with a TRGB Distance of 30 Mpc
Timothy Carleton, Timothy Ellsworth-Bowers, Rogier A. Windhorst +25
A wealth of observations have long suggested that the vast majority of isolated classical dwarf galaxies (- M) are currently star-forming. However, recent o…
The JWST Discovery of the Triply-imaged Type Ia "Supernova H0pe" and Observations of the Galaxy Cluster PLCK G165.7+67.0
Brenda L. Frye, Massimo Pascale, Justin Pierel +39
A Type Ia supernova (SN) at was discovered in James Webb Space Telescope Near Infrared Camera imaging of the galaxy cluster PLCK G165.7+67.0 (G165; ). The SN is…
EPOCHS VII: Discovery of high redshift () AGN candidates in JWST ERO and PEARLS data
Ignas Juodžbalis, Christopher J. Conselice, Maitrayee Singh +24
We present an analysis of a sample of robust high redshift galaxies selected photometrically from the `blank' fields of the Prime Extragalactic Areas for Reionization Science (PEAR…
EPOCHS IX. When cosmic dawn breaks: Evidence for evolved stellar populations in galaxies from PEARLS GTO and public NIRCam imaging
James A. A. Trussler, Christopher J. Conselice, Nathan Adams +28
The presence of evolved stars in high-redshift galaxies can place valuable indirect constraints on the onset of star formation in the Universe. Thus we use PEARLS GTO and public NI…
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…
JWST's PEARLS: Transients in the MACS J0416.1-2403 Field
Haojing Yan, Zhiyuan Ma, Bangzheng Sun +27
With its unprecedented sensitivity and spatial resolution, the James Webb Space Telescope (JWST) has opened a new window for time-domain discoveries in the infrared. Here we report…
Hidden giants in JWST's PEARLS: An ultra-massive z=4.26 sub-millimeter galaxy that is invisible to HST
