An unambiguous AGN and a Balmer break in an Ultraluminous Little Red Dot at z=4.47 from Ultradeep UNCOVER and All the Little Things Spectroscopy
Ivo Labbe, Jenny E. Greene, Jorryt Matthee +37
We present a detailed exploration of the most optically-luminous Little Red Dot (erg/s, erg/s, F444W=22AB) found to date. Located in the Abell 2744 fie…
Environmental Evidence for Overly Massive Black Holes in Low Mass Galaxies and a Black Hole - Halo Mass Relation at
Jorryt Matthee, Rohan P. Naidu, Gauri Kotiwale +14
JWST observations have unveiled faint active galactic nuclei (AGN) at high-redshift that provide insights on the formation of supermassive black holes (SMBHs) and their coevolution…
COSMOS2020: Disentangling the Role of Mass and Environment in Star Formation Activity of Galaxies at
Sina Taamoli, Negin Nezhad, Bahram Mobasher +14
The role of internal and environmental factors in the star formation activity of galaxies is still a matter of debate, particularly at higher redshifts. Leveraging the most recent…
Modelling of long gamma-ray burst host galaxies at cosmic noon from damped Lyman-α absorption statistics
J. -K. Krogager, A. De Cia, K. E. Heintz +11
We study the properties of long gamma-ray burst (GRB) host galaxies using a statistical modelling framework derived to model damped Lyman- absorbers (DLAs) in quasar spectra at…
RUBIES: JWST/NIRSpec resolves evolutionary phases of dusty star-forming galaxies at
Olivia R. Cooper, Gabriel Brammer, Kasper E. Heintz +24
The dearth of high quality spectroscopy of dusty star-forming galaxies (DSFGs) -- the main drivers of the assembly of dust and stellar mass at the peak of activity in the Universe…
All the Little Things in Abell 2744: 1000 Gravitationally Lensed Dwarf Galaxies at from JWST NIRCam Grism Spectroscopy
Rohan P. Naidu, Jorryt Matthee, Ivan Kramarenko +31
Dwarf galaxies hold the key to crucial frontiers of astrophysics, however, their faintness renders spectroscopy challenging. Here we present the JWST Cycle 2 survey, All the Little…
21 Balmer Jump Street: The Nebular Continuum at High Redshift and Implications for the Bright Galaxy Problem, UV Continuum Slopes, and Early Stellar Populations
Harley Katz, Alex J. Cameron, Aayush Saxena +11
We study the physical origin and spectroscopic impact of extreme nebular emission in high-redshift galaxies. The nebular continuum, which can appear during an extreme starburst, is…
A massive, neutral gas reservoir permeating a galaxy proto-cluster after the reionization era
Kasper E. Heintz, Jake S. Bennett, Pascal A. Oesch +21
Galaxy clusters are the most massive, gravitationally-bound structures in the Universe, emerging through hierarchical structure formation of large-scale dark matter and baryon over…
Uncovering the physical origin of the prominent Lyman- emission and absorption in GS9422 at
Chamilla Terp, Kasper E. Heintz, Darach Watson +5
We present a comprehensive spectro-photometric analysis of the galaxy GS9422 from the JADES GTO survey located at , anomalously showing a simultaneous strong Ly emissio…
The JWST-PRIMAL Legacy Survey. A JWST/NIRSpec reference sample for the physical properties and Lyman- absorption and emission of galaxies at
K. E. Heintz, G. B. Brammer, D. Watson +45
One of the surprising early findings with JWST has been the discovery of a strong "roll-over" or a softening of the absorption edge of Ly in a large number of galaxies at ($z\gt…
Outshining in the Spatially Resolved Analysis of a Strongly-Lensed Galaxy at z=6.072 with JWST NIRCam
C. Giménez-Arteaga, S. Fujimoto, F. Valentino +19
We present JWST/NIRCam observations of a strongly-lensed, multiply-imaged galaxy at , with magnification factors >~20 across the galaxy. We perform a spatially-resolved an…
