Hunting Wandering 3<z<8 Black Holes: Spatial Offsets in Ionization Ratio and Continuum Emission
Urvi Thakurdesai, Anthony J. Taylor, Steven L. Finkelstein +14
The early growth and assembly of supermassive black holes (SMBHs) remain key topics of interest in galaxy evolution. One of the scenarios predicted by theoretical models is that fr…
Spectroscopic confirmation of a large and luminous galaxy with weak emission lines at
Callum T. Donnan, Derek J. McLeod, Ross J. McLure +15
We present JWST/NIRSpec PRISM observations of a robust galaxy candidate at , selected from pure-parallel NIRCam imaging; PAN-z14-1. The NIRSpec spectrum allows confirmat…
A Morphology Catalog of Galaxies in CEERS: Evolution in the Size and Color Gradients of Galaxies Since Cosmic Dawn
Elizabeth J. McGrath, Steven L. Finkelstein, Guillermo Barro +42
We present measurements of morphological parameters from fitting 53,885 galaxies detected to a magnitude limit of F356W in the CEERS NIRCam imaging with galfit in six broad…
Galaxies in the Epoch of Reionization Are All Bark and No Bite -- Plenty of Ionizing Photons, Low Escape Fractions
Casey Papovich, Justin W. Cole, Weida Hu +27
Early results from JWST suggest that epoch-of-reionization (EoR) galaxies produce copious ionizing photons, which, if they escape efficiently, could cause reionization to occur too…
The BoRG- Survey: Abundance and Mass-to-light Ratio of Luminous Galaxies from Independent Sight Lines with NIRSpec
SofÃa Rojas-Ruiz, Micaela B. Bagley, Guido Roberts-Borsani +12
We present new results on the rest-frame UV luminosity function (UVLF) and stellar mass-to-light (M/L) ratio of bright (M mag) spectroscopically-confirmed gal…
From "The Cliff" to "Virgil": Mapping the Spectral Diversity of Little Red Dots with JWST/NIRSpec
Guillermo Barro, Pablo G. Perez-Gonzalez, Dale Kocevski +26
One of JWST's most unexpected discoveries is the emergence of "Little Red Dots'' (LRDs): compact sources at with blue rest-frame UV continua, red optical slopes, and…
