Neutrino Flavor Transformation in Collapsing Supermassive Objects
Kyle S. Kehrer, George M. Fuller, Ian Padilla-Gay +1
The collapse of supermassive stars (SMSs, ) to black holes is accompanied by a prodigious flux of neutrinos of all flavors. These are produced thermally via…

Early Formation of Supermassive Black Holes via Dark Star Gravitational Instability
Katherine Freese, George M. Fuller, Sohan Ghodla +4
We show that dark stars, which are dark-matter-powered stars in the early universe, can grow by accretion to masses in the range $\mathscr{O}\left ({10}^4\right )-\mathscr{O}\left…

Dark Matter-Powered Stars and the High-Redshift Tidal Disruption Event Rate
Thomas H. T. Wong, George M. Fuller
Tidal disruption events (TDEs) result from stars being gravitationally-scattered into low angular momentum orbits around massive black holes. We show that the short lifetimes of ma…
