From Giant Envelopes to Rapidly Contracting Cores in Rotating Population III Stars from to
Devesh Nandal, John Chisholm, Daniel J. Whalen +4
Population III (Pop III) stars link the chemical enrichment of the early Universe to the formation of the first massive black holes, yet their evolution remains poorly understood a…
Stellar Yields of Rapidly Rotating Population III Stars for the High Redshift Universe
Devesh Nandal, Konstantinos Topalakis, Vasilisa Sergienko +6
JWST has revealed rapid nitrogen enrichment in high redshift galaxies, renewing the need for stellar yields that follow metal free stars beyond the main sequence and across their f…
Little Red Dots are Direct-Collapse Black Hole-Forming Galaxies
Daniel J. Whalen, Muhammad A. Latif, Konstantinos Topalakis +3
"Little Red Dots" (LRDs) at are one of the most challenging discoveries by JWST to date because their distinctive V-shaped spectra and compact morphologies (100 - 200 p…
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…
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…
Little Red Dots as Intermediate Mass, Super-Eddington Engines: Insights from Type IIn Supernovae and The 1837-1856 Great Eruption of Carinae
Rohan P. Naidu, Jorryt Matthee, Anna de Graaff +20
JWST's Little Red Dots (LRDs) display a unique constellation of features that do not occur simultaneously in any other class of galaxies or AGN. Here we observe that many of these…
SEEDZ: Rapid Galaxy Assembly as a Pathway to Supermassive Stars, Dense Stellar Environments and Massive Black Hole Seeds
Lewis R. Prole, John A. Regan, Daxal Mehta +14
We investigate the assembly history of early galaxies in the SEEDZ hydrodynamic simulations, to investigate the high inflow rates believed to be required for the formation of super…
The formation of supermassive black holes from Population III.1 seeds. IV. Self-regulated seeding from supermassive star ionizing feedback
Maya A. Petkova, Jonathan C. Tan, Jasbir Singh +5
Supermassive Population III.1 stars, i.e., formed from pristine, metal-free gas leading to conditions where dark matter annihilation heating is significant, have been proposed as t…
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…
Habitable Zones Around Massive Stars: From the Main Sequence to Supergiants
Devesh Nandal, Abraham Loeb
Massive stars dominate the feedback of young stellar populations, yet their ultraviolet fields and winds are often presumed to preclude Earth like habitability. We test this by map…
