Probing the Nature of Dark Matter Self-Interactions Through Observations of Massive Black Hole Mergers
Zachary J. Hoelscher, Kelly Holley-Bockelmann, Akaxia Cruz +1
Though the nature of dark matter remains elusive, two models have come to prominence with testable predictions: cold dark matter (CDM) and self-interacting dark matter (SIDM). Whil…

Self-Interacting Dark Matter and the Delay of Super-Massive Black Hole Growth
Akaxia Cruz, Andrew Pontzen, Marta Volonteri +6
Using cosmological hydrodynamic simulations with physically motivated models of super-massive black hole (SMBH) formation and growth, we compare the assembly of Milky Way-mass ( $M…
