Pulsational mass loss from supermassive stars creates the compact shells of Little Red Dots
Devesh Nandal, Igor Chilingarian, Chris Nagele +3
Little Red Dots (LRDs) have emerged as one of the central puzzles of the JWST era. Their spectra increasingly require dense gas close to the source, yet the physical origin of that…

Cosmic Outliers: Low-Spin Halos Explain the Abundance, Compactness, and Redshift Evolution of the Little Red Dots
Fabio Pacucci, Abraham Loeb
The Little Red Dots (LRDs) are high-redshift galaxies uncovered by JWST, characterized by small effective radii ( pc), number densities that are intermedia…
