Magnetic Penrose process (MPP) is not only the most exciting and fascinating process
mining the rotational energy of black hole but it is also the favored astrophysically viable …

Binary black hole (BBH) mergers provide a prime source for current and future
interferometric gravitational wave observatories. Massive BBH mergers may often take place …

We construct an approximate metric that represents the spacetime of spinning binary black
holes (BBH) approaching merger. We build the metric as an analytical superposition of two …

A bstract The Bondi-van der Burg-Metzner-Sachs (BMS) group is the asymptotic symmetry
group of asymptotically flat spacetime. It is infinite dimensional and entails an infinite number …

The Blandford-Znajek process, which uses a magnetized plasma to extract energy from a
rotating black hole, is one of the leading candidates for powering relativistic jets. In this work …

A bstract The Bondi-van der Burg-Metzner-Sachs (BMS) group is the asymptotic symmetry
group of asymptotically flat gravity. Recently, Donnay et al. have derived an analogous …

Here we investigate the energetics of the charged-rotating-NUT-Kiselev black hole (CRNK-
BH) in the Rastall modified theory of gravity. First, we study the dependence of the …

Superradiance is a radiation enhancement process that involves dissipative systems. With a
60 year-old history, superradiance has played a prominent role in optics, quantum …

Direct detection of black hole-neutron star pairs is anticipated with the advent of aLIGO.
Electromagnetic counterparts may be crucial for a confident gravitational-wave detection as …

Force-free electrodynamics (FFE) describes a particular regime of magnetically dominated
relativistic plasmas, which arises on several astrophysical scenarios of interest such as …
