Binaries comprised of a neutron star (NS) and a black hole (BH) have so far eluded
observations as pulsars and with gravitational waves (GWs). We model the formation and …

The detection of a pulsar (PSR) in a tight, relativistic orbit around a supermassive or
intermediate-mass black hole–such as those in the Galactic centre or in the centre of …

We investigate the propagation of light through a plasma on a background Kerr space–time
via a Hamiltonian formulation. The behaviour of light when propagating through a vacuum …

Binary pulsars allow us to carry out precision tests of gravity and have placed stringent
bounds on a broad class of theories beyond general relativity. Current and future radio …

Radio timing observations of a millisecond pulsar in orbit around the Galactic centre black
hole (BH) or a BH at the centre of globular clusters could answer foundational questions in …

A bstract The strong version of the nonviolent nonlocality proposal of Giddings predicts
“strong but soft” quantum metric fluctuations near black hole horizons in an attempt to …

Pulsars (PSRs) orbiting intermediate or supermassive black holes at the centre of galaxies
and globular clusters are known as Extreme Mass Ratio Binaries (EMRBs) and have been …

We argue that the Black Hole-Neutron Star (BH-NS) binaries are the natural astrophysical
probes of quantum gravity in the context of the new era of multi-messenger astronomy. In …

Pulsars (PSRs) are some of the most accurate clocks found in nature, while black holes
(BHs) offer a unique arena for the study of quantum gravity. As such, PSR–BH binaries …
