Using Ly Transmitted Spectrum to Probe IGM Transmission and Identify Ionized Structures in Cosmic Reionization

Weida Hu, Casey Papovich, Lu Shen +16

We present a study of intergalactic medium (IGM) transmission at using high-signal-to-noise JWST/NIRSpec prism spectroscopy of 143 galaxies at from the CAPE…

Extreme Emission Line Galaxies in CEERS Are Powered by Star Formation, not AGN

Kelcey Davis, Madisyn Brooks, Jonathan R. Trump +28

We present a spectroscopic study of photometrically identified extreme emission-line galaxies (EELGs) with observed-frame equivalent widths (EWs) >5000 A of either H alpha or H bet…

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…

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…

The AGN nature of strong CIII emitters in the Early Universe with JWST

F. Arevalo-Gonzalez, R. Tripodi, M. Llerena +21

The semi-forbidden CIII] 1907,1909 doublet is a key tracer of high-ionization emission in the early universe. We present a study of CIII] emission in galaxies at z=5-7, using p…

THRILS -- The High-(Redshift+Ionization) Line Search: Program Description & Redshift Catalog

Taylor A. Hutchison, Rebecca L. Larson, Pablo Arrabal Haro +46

To date, many spectroscopic confirmations of z>7 galaxies have been obtained using JWST/NIRSpec prism observations, with most of their physical properties inferred from these obser…
