The Ashes of Supermassive Stars: Globular Cluster-like Aluminum Enhancement in Little Red Dots
V. Kokorev, J. Chisholm, R. P. Naidu +16
The relative abundances of elements in galaxies serve as fossil records of the physical conditions and processes by which they were forged. While the Big Bang produced only the lig…
An Optical Illusion: High Electron Densities Create Extremely Metal-Poor Galaxy Impostors
Tiger Yu-Yang Hsiao, Danielle A. Berg, Steven L. Finkelstein +8
JWST has enabled the discovery of dozens of extremely metal-poor galaxies (EMPGs) with metallicities below , representing a significant leap toward detecting the fi…
A Glimpse of the Low-Mass End of the Direct Mass-Metallicity Relation at
Tiger Yu-Yang Hsiao, John Chisholm, Danielle A. Berg +22
The competition between metal synthesis and feedback from massive stars establishes the mass-metallicity relation (MZR) at low-redshifts. Examining this relation at higher redshift…
The GlimmIr: Spectroscopic Variability in a z~7 LRD Indicates Rapid Changes in Both the Narrow and Broad Line Regions
Erini Lambrides, Taylor A. Hutchison, Rebecca L. Larson +39
The enigmatic population of ``Little Red Dots'' (LRDs) sit at the center of some of the largest debates in extragalactic astronomy today. The source(s) of ionizing emission and the…
The Prevalence of Turbulence-Regulated Multiphase Galactic Winds in Star-Forming Galaxies
Zhihui Li, Timothy Heckman, Max Gronke +8
We build upon our previously developed multi-ion radiative transfer (RT) framework, PEACOCK, to investigate the kinematic and energetic structure of cool-to-warm galactic winds in…
Kinematically Coherent Multiphase Galactic Winds in Star-Forming Galaxies Revealed by Unified Radiative Transfer Modeling of UV Emission and Absorption Lines
Zhihui Li, Timothy Heckman, Max Gronke +8
We present PEACOCK, a three-dimensional Monte Carlo radiative transfer (RT) framework designed to self-consistently model rest-frame ultraviolet emission and absorption lines arisi…
Little Red Dots as Globular Clusters in Formation
John Chisholm, Danielle A. Berg, Michael Boylan-Kolchin +7
Little Red Dots (LRDs), among the most enigmatic high-redshift discoveries by JWST, are commonly believed to be powered by accreting supermassive black holes. Here, we explore the…
A GLIMPSE into the UV Continuum Slopes of the Faintest Galaxies in the Epoch of Reionization
Michelle C. Jecmen, John Chisholm, Hakim Atek +23
As observations have yet to constrain the ionizing properties of the faintest (M > -16) galaxies, their contribution to cosmic reionization remains unclear. The rest-fra…
