A dense, metal-rich absorber driven by a heavily dust-obscured galaxy: The direct evidence of CGM enrichment at

Qinyue Fei, Seiji Fujimoto, Gabriel Brammer +23

We report the serendipitous discovery of a dense, metal-enriched circumgalactic medium (CGM) absorber at z=7.03, together with its host galaxy, identified along the sightline towar…

A data processing pipeline for the WINTER near-infrared surveyor using the framework

Viraj Karambelkar, Robert Stein, Danielle Frostig +18

We present the data reduction and transient detection pipeline for the Wide-field Infrared Transient Explorer (WINTER) surveyor and report its on-sky performance. The WINTER camera…

Overmassive No More: The Case for Little Red Dots Hosting Black Hole Seeds as Massive as Single Supermassive Stars

Wendy Q. Sun, Rohan P. Naidu, Hanpu Liu +17

Little Red Dots (LRDs) display singular properties unlike any known class of AGN or galaxies, motivating novel mass estimators for their central engines. Inspired by their similari…

Can Little Red Dots Contribute To The Early Universe Cosmic Dust Budget?

Chris Ashall, Rohan P. Naidu, Alberto Torralba +11

The origin of dust in the early Universe remains uncertain. We explore whether Little Red Dots (LRDs) could provide a high-redshift dust-production channel. Motivated by an analogy…

Cool CGM MgII Absorption Across the Star-Forming, Green Valley, and Quiescent Transition

Simon Xinlin Wu, Rongmon Bordoloi, Robert A. Simcoe +4

We investigate the distribution and kinematics of cool circumgalactic medium (CGM) gas across the star-forming to quiescent transition using MgII absorption for 716 galaxies spanni…

Fundamental Noise Limits of Infrared Detectors in the Presence of Readout Glow

Michael Bottom, Gustav Pettersson, Pavaman Bilgi +5

Read noise in infrared sensor arrays remains a major obstacle for ground- and space-based astronomy. It has long been recognized that the upcoming extremely large telescopes cannot…
