SPAM: Survey Overview and JWST/NIRCam Multi-Band Photometry Catalog

Rebecca L. Larson, Kelcey Davis, Hollis B. Akins +46

We present the Star-formation from Photometry through the Addition of Medium-bands (SPAM) survey, a 62.9 hr JWST/NIRCam imaging program to add ten new filters, nine medium-band fil…

Cosmic Collisions I: Optical Morphologies for MIRI-selected galaxies from the PRIMER survey

Gregory Troiani, Allison Kirkpatrick, Leyna Bajaj +7

We present the first results of visual morphology classifications from the Cosmic Collisions project, comprising 14,657 galaxies from the JWST Public Release IMaging for Extragalac…

JWST evidence for a sharp "Cosmic Daybreak" at z = 15

Jiashuo Zhang, Tom Broadhurst, Tzihong Chiueh +9

Luminous young galaxies have been uncovered with relative ease by JWST, extending to z=14.5, so it is puzzling that deeper spectroscopy of fainter candidates now finds only interlo…

Quiescent Galaxies at from CAPERS spectroscopy and their Number densities

Lu Shen, Weida Hu, Casey Papovich +28

Recent JWST observations have revealed an overabundance of quiescent galaxies at high redshift. Photometric methods, such as photometry-derived sSFRs, colors, and synthetic $…

The THRILS Factor: Investigating the properties of Little Red Dots (LRDs) at 3<z<6 with JWST/NIRSpec

Ananya Ganapathy, Rebecca L. Larson, Erini Lambrides +20

JWST has uncovered a class of objects called LRDs, whose nature is still widely debated. In this work, we present a comprehensive spectroscopic analysis of nine LRDs in the Extende…

Skyfire: A Spectroscopic Census of Little Red Dots and Broad-Line AGN in the CEERS Field

Dale D. Kocevski, Anthony J. Taylor, Masafusa Onoue +24

We present the Skyfire program, a 21-hour Cycle 3 JWST/NIRSpec survey with the G395M medium-resolution grating covering five pointings in the Extended Groth Strip. The survey is de…

How can we finally see the first light? Status and perspective in the search for Population III stars

Alessandra Venditti, Daniel Schaerer, Erik Zackrisson +26

Finding the first (Population III or Pop III) stars is one of the fundamental quests of astronomy, aiming to deliver the missing link in how stars form at early cosmic times. Yet t…

Deep Spectroscopic Follow-Up of Maisie's Galaxy -- A Typical Galaxy in the Early Universe

Rebecca L. Larson, Taylor A. Hutchison, Steven L. Finkelstein +26

The first several years of JWST observations have yielded surprisingly large numbers of bright galaxies, with follow-up spectroscopy of many of these sources implying extrem…

The MIRI Early Obscured-AGN Wide Survey (MEOW): A Population of Hidden AGN at Revealed by JWST/MIRI Imaging

Gene C. K. Leung, Anna-Christina Eilers, Ryan Endsley +25

We present the MIRI Early Obscured-AGN Wide Survey (MEOW), a JWST/MIRI imaging survey designed to detect dust-obscured active galactic nuclei (AGN) across cosmic time, with a parti…

The quasi-star model for Little Red Dots: potential and challenges

Fabrizio Gentile, Mauro Giavalisco, Emanuele Daddi +25

(Abridged) Little Red Dots (LRDs) are a class of sources discovered by JWST observationally defined by a "V-shaped" rest-frame UV-Optical SED, a compact or unresolved morphology, a…

The Collective Voice of Ly Emitters: Insights from JWST Stacked Spectroscopy

R. Tripodi, L. Napolitano, L. Pentericci +20

We present a spatially resolved stacked analysis of 287 LAEs at observed with JWST/NIRSpec prism spectroscopy. By constructing a two-dimensional stack from public surveys (CA…
