Impact of subhalo dynamical friction heating on the formation of the first structures in the universe
Zhenyu Wu, Sadegh Khochfar, Muhammad A. Latif +2
We present a model for gas heating, driven by dynamical friction from orbiting subhalos within dark matter halos. Using data from the TNG50 simulation, we derive the subhalo mass f…

Conditions for Super-Eddington Accretion onto the First Black Holes
Simone T. Gordon, Britton D. Smith, Sadegh Khochfar +1
Observations of supermassive black holes at high redshift challenge our understanding of the evolution of the first generation of black holes (BHs) in proto-galactic environments.…

A Heavy Seed Black Hole Mass Function at High Redshift -- Prospects for LISA
Joe McCaffrey, John Regan, Britton Smith +3
The advent of new and near-future observatories probing the earliest epochs of the Universe has opened the opportunity to investigate the formation and growth of the first massive…
