Super-Eddington Accretion and Feedback from the First Massive Seed Black Holes
John A. Regan, Turlough P. Downes, Marta Volonteri +4
Super-Eddington accretion onto massive black hole seeds may be commonplace in the early Universe, where the conditions exist for rapid accretion. Direct collapse black holes are of…
Titans of the Early Universe: The Prato Statement on the Origin of the First Supermassive Black Holes
Tyrone E. Woods, Bhaskar Agarwal, Volker Bromm +30
In recent years, the discovery of massive quasars at z~7 has provided a striking challenge to our understanding of the origin and growth of supermassive black holes in the early Un…
Gravitational Wave Signals from the First Massive Black Hole Seeds
Tilman Hartwig, Bhaskar Agarwal, John A. Regan
Recent numerical simulations reveal that the isothermal collapse of pristine gas in atomic cooling haloes may result in stellar binaries of supermassive stars with $M_* \gtrsim 10^…
The Growth of Black Holes from Population III Remnants in the Renaissance Simulations
Britton Smith, John Regan, Turlough Downes +3
The formation of stellar mass black holes from the remnants of Population III stars provides a source of initial black hole seeds with the potential to grow into intermediate or, i…
Rise of the First Super-Massive Stars
John A. Regan, Turlough P. Downes
We use high resolution adaptive mesh refinement simulations to model the formation of massive metal-free stars in the early Universe. By applying Lyman-Werner (LW) backgrounds of 1…
