COSMOS-3D: Spectro-photometric Confirmation of Shabgard, a Cool, Metal-poor Brown Dwarf in the COSMOS Field

Bahareh S. Salmasi, Priyanka Jalan, Tomotsugu Goto +19

Brown dwarfs are unique laboratories for studying cool atmospheres, the low-mass end of star formation, and the transition between stars and giant planets. Identifying and characte…

CHAMPS: Data Reduction and Detection of ~3300 Dusty Galaxies at 1.2 mm

Felix Martinez, Jeyhan S. Karaltepe, Andreas L. Faisst +52

We present the reduction and source catalogs for the \textit{COSMOS High- ALMA-MIRI Population Survey} (CHAMPS), the largest Atacama Large (Sub)Millimeter Array (ALMA) blank fie…

COSMOS-3D: Diverse Environments and Hot-dust Signatures among Dusty Star-forming Galaxies at = 4.9-7.2

Siwei Zou, Manuel Aravena, Shaoze Geng +20

Dusty star-forming galaxies (DSFGs) are expected to trace early massive-halo assembly, but the connection between dust-obscured star formation, morphology, hot dust, and environmen…

Precise C-N-O Abundances of Individual Galaxies in the First Billion Years from Ultra-Deep, Rest-UV-to-Optical JWST Spectroscopy

Raunaq Singh Rai, Guido Roberts-Borsani, Ryan Sanders +8

We present ultra-deep JWST/NIRSpec spectroscopy of nine star-forming galaxies at in the GOODS-N field, drawn from the Origins of Metal Enrichment in Galaxie…

A tidal disruption event in a quasar at redshift 7.19

S. Fujimoto, Q. Fei, G. B. Brammer +41

We report a long-lived nuclear transient in GNz7q, a red quasar at powered by a black hole and hosted by a compact, dusty starburst galaxy. Th…

Reionization driven by the few: the ionizing budget of galaxies at z=5-10 from JWST/NIRSpec

Emma Giovinazzo, Pascal A. Oesch, Anne Verhamme +5

The sources responsible for the Epoch of Reionization (EoR), the last major phase transition of the Universe, remain highly elusive. While JWST has begun to illuminate the properti…

Too many protoclusters? Reconciling the overabundance of cluster progenitors within the first billion years of the Universe

Callum Witten, Jake S. Bennett, Pascal A. Oesch +8

JWST has revealed an overabundance of apparent (`Coma'-like) cluster progenitors at that is two (300) times in excess of, and in () tension with, the number…

Connecting CGM enrichment with Lyman alpha emitters at 2.9 < z < 6.7

A. M. Sebastian, E. Ryan-Weber, R. L. Davies +2

We present the results of a blind search for Lyman emitters (LAEs) in three deep archival quasar fields from VLT/MUSE using state-of-the-art detection algorithms. We e…

Life After the Quasar: Overmassive Black Holes and Remnant Ionised Bubbles in and Around Two z~6.6 Galaxies

Romain A. Meyer, Pascal A. Oesch, Callum Witten +7

Supermassive black holes (SMBH, ) powering luminous quasars already exist one billion years after the Big Bang, yet their connection to their star-formi…

The Engine and its Flows: Little Red Dot spectra are shaped by the column densities of their gas envelopes

Jorryt Matthee, Alberto Torralba, Gabriele Pezzulli +23

JWST data have enabled the abundant identification of compact broad Balmer line sources nicknamed the Little Red Dots. While they share broad lines with active galactic nuclei, the…

Direct pathway to the Early Supermassive Black Holes: A Red Super-Eddington Quasar in a Massive Starburst Host at

Qinyue Fei, Seiji Fujimoto, Gabriel Brammer +24

We present a panchromatic optical-mm characterization of GNz7q, a recently identified X-ray weak, rapidly growing red quasar embedded within a dusty starburst galaxy at ,…

Characterising Ly damping wings at the onset of reionisation: Evidence for highly efficient star formation driven by dense, neutral gas in UV-bright galaxies at

Clara L. Pollock, Kasper E. Heintz, Joris Witstok +23

One of the major conundrums in contemporary extragalactic astrophysics is the apparent overabundance of a remarkable population of UV-bright galaxies at redshifts . We…

From Grism to IFU: Revising the Redshift and Nature of the Massive Dusty Galaxy S1 with JWST and ALMA

Mengyuan Xiao, Longji Bing, Gabriel Brammer +21

We report a revised spectroscopic redshift for the dusty massive galaxy S1, previously inferred with an exceptionally high baryon-to-star conversion efficiency from NIRCam slitless…

A JWST Paschen-alpha Calibration of the Radio Luminosity-Star Formation Rate Relation at z~1.3

Nick Seymour, Catherine Hale, Imogen Whittam +17

As radio emission from normal galaxies is a dust-free tracer of star formation, tracing the star formation history of the Universe is a key goal of the SKA and ngVLA. In order to i…
