New Lyman-alpha Emitters in EGS: Evidence of an Extended Ionized Structure at
Intae Jung, Steven L. Finkelstein, Rebecca L. Larson +21
We perform a ground-based near-infrared spectroscopic survey using the Keck/MOSFIRE spectrograph to target Ly emission at from 61 galaxies to trace the ionization st…
CEERS Key Paper III: The Diversity of Galaxy Structure and Morphology at z=3-9 with JWST
Jeyhan S. Kartaltepe, Caitlin Rose, Brittany N. Vanderhoof +58
We present a comprehensive analysis of the evolution of the morphological and structural properties of a large sample of galaxies at z=3-9 using early JWST CEERS NIRCam observation…
JWST reveals a possible galaxy merger in triply-lensed MACS0647JD
Tiger Yu-Yang Hsiao, Dan Coe, Abdurro'uf +63
MACS0647JD is a triply-lensed galaxy originally discovered with the Hubble Space Telescope. Here we report new JWST imaging, which clearly resolves MACS0647JD as ha…
ALMA Observation of a Galaxy Candidate Discovered with JWST
Ilsang Yoon, Christopher L. Carilli, Seiji Fujimoto +12
We report the ALMA observation of a galaxy candidate (GHZ1) discovered from the GLASS-JWST Early Release Science Program. Our ALMA program aims to detect the [OIII] em…
High-Redshift Galaxy Candidates at as Revealed by JWST Observations of WHL0137-08
Larry D. Bradley, Dan Coe, Gabriel Brammer +25
We report the discovery of four galaxy candidates observed 450 - 600 Myr after the Big Bang with photometric redshifts between z ~ 8.3 - 10.2 measured using the JWST NIRCam imaging…
CLEAR: High-Ionization [Ne V] 3426 Emission-line Galaxies at
Nikko J. Cleri, Guang Yang, Casey Papovich +13
We analyze a sample of 25 [Ne V] 3426 emission-line galaxies at using Hubble Space Telescope/Wide Field Camera 3 G102 and G141 grism observations from the CANDELS Ly…
Stellar Populations of Lyman-alpha Emitting Galaxies in the HETDEX Survey I: An Analysis of LAEs in the GOODS-N Field
Adam P. McCarron, Steven L. Finkelstein, Oscar A. Chavez Ortiz +17
We present the results of a stellar-population analysis of Lyman-alpha emitting galaxies (LAES) in GOODS-N at 1.9 < z < 3.5 spectroscopically identified by the Hobby-Eberly Telesco…
JWST Imaging of Earendel, the Extremely Magnified Star at Redshift
Brian Welch, Dan Coe, Erik Zackrisson +60
The gravitationally lensed star WHL0137-LS, nicknamed Earendel, was identified with a photometric redshift based on images taken with the Hubble Space Tele…
Dusty Starbursts Masquerading as Ultra-high Redshift Galaxies in JWST CEERS Observations
Jorge A. Zavala, Veronique Buat, Caitlin M. Casey +121
Lyman Break Galaxy (LBG) candidates at z>10 are rapidly being identified in JWST/NIRCam observations. Due to the (redshifted) break produced by neutral hydrogen absorption of rest-…
CLEAR: Spatially Resolved Emission Lines and Active Galactic Nuclei at

We investigate spatially-resolved emission-line ratios in a sample of 219 galaxies () detected using the G102 grism on the \emph{Hubble Space Telescope} Wide Field Camer…
A Long Time Ago in a Galaxy Far, Far Away: A Candidate z ~ 12 Galaxy in Early JWST CEERS Imaging
Steven L. Finkelstein, Micaela B. Bagley, Pablo Arrabal Haro +117
We report the discovery of a candidate galaxy with a photo-z of z~12 in the first epoch of the JWST Cosmic Evolution Early Release Science (CEERS) Survey. Following conservative se…
