Abstract The Laser Interferometer Space Antenna (LISA) will be a transformative experiment
for gravitational wave astronomy, and, as such, it will offer unique opportunities to address …

This review covers the main aspects of black hole accretion disk theory. We begin with the
view that one of the main goals of the theory is to better understand the nature of black holes …

A black hole x-ray binary (XRB) system forms when gas is stripped from a normal star and
accretes onto a black hole, which heats the gas sufficiently to emit x-rays. We report a …

Astrophysical black hole candidates are thought to be the Kerr black holes of general
relativity, but there is not yet direct observational evidence that the spacetime geometry …

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 …

Stellar-mass black holes and neutron stars represent extremes in gravity, density, and
magnetic fields. They therefore serve as key objects in the study of multiple frontiers of …

We investigate the shadow cast by a rotating braneworld black hole, in the Randall-
Sundrum scenario. In addition to the angular momentum, the tidal charge term deforms the …

The Chern-Simons modification to general relativity in four dimensions consists of adding to
the Einstein-Hilbert term a scalar field that couples to the first-class Pontryagin density. In …

A typical galaxy is thought to contain tens of millions of stellar-mass black holes, the
collapsed remnants of once massive stars, and a single nuclear supermassive black hole …

We study the shadow produced by a spinning Kaluza-Klein black hole in Einstein gravity
coupled to a Maxwell field and a dilaton. The size and the shape of the shadow depend on …
