The Dynamical Evolution of Stellar Black Holes in Globular Clusters

, 2014
Our current understanding of the stellar initial mass function and massive star evolution suggests that young globular clusters may have formed hundreds to thousands of stellar-mass black holes, the remnants of stars with initial masses from $\sim 20 ...

Black Hole Starvation and Bulge Evolution in a Milky Way-like Galaxy [PDF]

, 2015
We present a new zoom-in hydrodynamical simulation, "Erisbh", which follows the cosmological evolution and feedback effects of a supermassive black hole at the center of a Milky Way-type galaxy.

Black Hole Spin via Continuum Fitting and the Role of Spin in Powering Transient Jets

, 2013
The spins of ten stellar black holes have been measured using the continuum-fitting method. These black holes are located in two distinct classes of X-ray binary systems, one that is persistently X-ray bright and another that is transient.

M-σ relations across cosmic time

The Open Journal of Astrophysics, 2023
Feedback from active galactic nuclei (AGN) has long been invoked to explain the correlation between black hole mass and stellar velocity dispersion (M-σ) discovered in low redshift galaxies. We describe the time evolution of AGN in the M-σ plane based on
