Evidence of violation of Case B recombination in Little Red Dots
G. P. Nikopoulos, D. Watson, A. Sneppen +4
Little Red Dots (LRDs) are a new class of compact extragalactic objects, with a v-shaped optical spectral energy distribution breaking close to the Balmer break wavelength, and bro…
JWST COSMOS-3D: Spectroscopic Census and Luminosity Function of [O III] Emitters at 6.75<z<9.05 in COSMOS
Romain A. Meyer, Feige Wang, Koki Kakiichi +38
We present a catalogue of spectroscopically selected [OIII]+Hb emitters at 6.75<z<9.05 and the resulting [OIII] 5008 ÅLuminosity Function (LF) in the COSMOS field. We leverage the…
JWST reveals a supernova following a gamma-ray burst at z 7.3
A. J. Levan, B. Schneider, E. Le Floc'h +50
The majority of energetic long-duration gamma-ray bursts (GRBs) are thought to arise from the collapse of massive stars, making them powerful tracers of star formation across cosmi…
The Infinity Galaxy: a Candidate Direct-Collapse Supermassive Black Hole Between Two Massive, Ringed Nuclei
Pieter van Dokkum, Gabriel Brammer, Josephine F. W. Baggen +3
We report the discovery of an unusual z=1.14 object, dubbed the galaxy, in JWST imaging of the COSMOS field. Its rest-frame near-IR light is dominated by two compact nucle…
Further Evidence for a Direct-Collapse Origin of the Supermassive Black Hole at the Center of the Infinity Galaxy
Pieter van Dokkum, Gabriel Brammer, Connor Jennings +2
The z=1.14 galaxy consists of two ringed nuclei with an active supermassive black hole (SMBH) in between them. The system is likely the result of a nearly face-on collisio…
The Structure and Formation Histories of Low-Mass Quiescent Galaxies in the Abell 2744 Cluster Environment
Sam E. Cutler, John R. Weaver, Katherine E. Whitaker +21
Low-mass quiescent galaxies are thought to predominantly reside in overdense regions, as environmental effects are often invoked to explain their shutdown of star formation. These…
A First Look at Spatially Resolved Star Formation at with JWST FRESCO NIRCam Slitless Spectroscopy
Jasleen Matharu, Erica J. Nelson, Gabriel Brammer +19
We present the first results on the spatial distribution of star formation in 454 star-forming galaxies at using H-Alpha emission-line maps and F444W imaging tracing th…
H-based Star Formation Rates in and around z 0.5 EDisCS clusters
Jennifer R. Cooper, Gregory H. Rudnick, Gabriel G. Brammer +14
We investigate the role of environment on star-formation rates of galaxies at various cosmic densities in well-studied clusters. We present the star-forming main sequence for 163 g…
Spectroscopic confirmation of a mature galaxy cluster at redshift two
J. P. Willis, R. E. A. Canning, E. S. Noordeh +6
Galaxy clusters are the most massive virialized structures in the Universe and are formed through the gravitational accretion of matter over cosmic time. The discovery of an evolve…
Galaxy mergers up to z<2.5 I : The star formation properties of merging galaxies at separations 3-15 kpc
Andrea Silva, Danilo Marchesini, John D. Silverman +7
We present a study of the influence of galaxy mergers on star formation at 0.3<z<2.5. Major mergers are selected from the CANDELS/3D-HST catalog using a peak-finding algorithm. Mer…
The Progenitors of Local Ultra-massive Galaxies Across Cosmic Time: from Dusty Star-bursting to Quiescent Stellar Populations
Danilo Marchesini, Adam Muzzin, Mauro Stefanon +8
Using the UltraVISTA catalogs, we investigate the evolution in the 11.4~Gyr since of the progenitors of local ultra-massive galaxies ($\log{(M_{\rm star}/M_{\odot})}\approx11…
