The existence of∼ 109M⊙ supermassive black holes (SMBHs) within the first billion years
of the Universe has stimulated numerous ideas for the prompt formation and rapid growth of …

The inefficiency of star formation in massive elliptical galaxies is widely believed to be
caused by the interactions of an active galactic nucleus (AGN) with the surrounding gas …

We present the first comprehensive study of r-process element nucleosynthesis in the ejecta
of compact binary mergers (CBMs) and their relic black hole (BH)–torus systems. The …

Expulsion of neutron-rich matter following the merger of neutron star binaries is crucial to the
radioactively powered electromagnetic counterparts of these events and to their relevance …

We present results from two long-duration general relativistic magneto-hydrodynamic
(GRMHD) simulations of advection-dominated accretion around a non-spinning black hole …

We investigate radiatively inefficient accretion flow models for Sgr A*, the supermassive
black hole in our Galactic center, in light of new observational constraints. Confirmation of …

Accretion disk theory was first developed assuming local heat balance where the energy
produced by viscous heating was emitted from the sides of the disk. One of the important …

We review the properties of 40 X-ray binaries that contain either a confirmed black hole or a
black hole candidate. After discussing briefly the significance of these Galactic black holes to …

The formation and large-scale propagation of Poynting-dominated jets produced by
accreting, rapidly rotating black hole systems are studied by numerically integrating the …

We present three-dimensional MHD simulations of rotating radiatively inefficient accretion
flows onto black holes. We continuously inject magnetized matter into the computational …
