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 Evolution of Pop III.1 Protostars Powered by Dark Matter Annihilation. II. Dependence on WIMP Properties
Konstantinos Topalakis, Devesh Nandal, Jonathan C. Tan
The rapid appearance of supermassive black holes (SMBHs) at requires efficient pathways to form massive black hole seeds. We investigate whether annihilation of weakly…
The evolution of protostars powered by dark matter annihilation. I. Fiducial model and first results
Devesh Nandal, Konstantinos Topalakis, Jonathan C. Tan +4
The existence of billion-solar-mass quasars at redshifts poses a formidable challenge to theories of black hole formation, requiring pathways for the rapid growth of…
