Constraints on the Gas Geometry Surrounding Little Red Dots through Narrow-Line Diagnostics
Visal Sok, Erica J. Nelson, Mitchell C. Begelman +10
Little Red Dots (LRDs) are a recently identified population of high-redshift sources, with a common interpretation being accreting black holes embedded within a spherical, opticall…
Little Red Dots As Late-stage Quasi-stars
Mitchell C. Begelman, Jason Dexter
We argue that the "Little Red Dots" (LRDs) discovered with the James Webb Space Telescope are quasi-stars in their late stages of evolution. Quasi-stars are hypothetical objects pr…
Quasi-stars as a Means of Rapid Black Hole Growth in the Early Universe
Eric R. Coughlin, Mitchell C. Begelman
JWST observations demonstrate that supermassive black holes (SMBHs) exist by redshifts , providing further evidence for "direct collapse" black hole (BH) formation, w…
Which came first: supermassive black holes or galaxies? Insights from JWST
Joseph Silk, Mitchell Begelman, Colin Norman +2
Insights from JWST observations suggest that AGN feedback evolved from a short-lived, high redshift phase in which radiatively cooled turbulence and/or momentum-conserving outflows…
