-- Hardware-agnostic Particle-in-Cell Code for Plasma Astrophysics. II: General Relativistic Module

Alisa Galishnikova, Hayk Hakobyan, Alexander Philippov +1

Black hole environments often host plasmas that are fully collisionless or contain intrinsically collisionless regions, including relativistic jets and coronae where particle energ…

A kinetic model of jet-corona coupling in accreting black holes

J. Mehlhaff, B. Cerutti, B. Crinquand

Black hole (BH) accretion disks are often coupled to ultramagnetized and tenuous plasma coronae close to their central BHs. The coronal magnetic field can exchange energy between t…

A kinetic study of black hole activation by local plasma injection into the inner magnetosphere

Idan Niv, Omer Bromberg, Amir Levinson +2

(Abridged) An issue of considerable interest in the theory of jet formation by the Blandford-Znajek mechanism, is how plasma is being continuously supplied to the magnetosphere to…

Reconnection-driven flares in 3D black hole magnetospheres -- A scenario for hot spots around Sagittarius A*

I. El Mellah, B. Cerutti, B. Crinquand

Low-luminosity supermassive and stellar-mass black holes (BHs) may be embedded in a collisionless and highly magnetized plasma. They show non-thermal flares indicative of efficient…

Images of magnetospheric reconnection-powered radiation around supermassive black holes

Benjamin Crinquand, Benoît Cerutti, Guillaume Dubus +2

Accreting supermassive black holes can now be observed at the event-horizon scale at mm wavelengths. Current predictions for the image rely on hypotheses (fluid modeling, thermal e…

Spinning black holes magnetically connected to a Keplerian disk -- Magnetosphere, reconnection sheet, particle acceleration and coronal heating

I. El Mellah, B. Cerutti, B. Crinquand +1

Context: Accreting black holes (BHs) may be surrounded by a highly magnetized plasma threaded by a poloidal magnetic field. Non-thermal flares and high energy components could orig…

Synthetic gamma-ray lightcurves of Kerr black-hole magnetospheric activity from particle-in-cell simulations

Benjamin Crinquand, Benoît Cerutti, Guillaume Dubus +2

Context: The origin of ultra-rapid flares of very high-energy radiation from active galactic nuclei remains elusive. Magnetospheric processes, occurring in the close vicinity of th…

Multi-dimensional simulations of ergospheric pair discharges around black holes

Benjamin Crinquand, Benoît Cerutti, Alexander Philippov +2

Black holes are known to launch powerful relativistic jets and emit highly variable gamma radiation. How these jets are loaded with plasma remains poorly understood. Spark gaps are…

Kinetic modeling of the electromagnetic precursor from an axisymmetric binary pulsar coalescence

Benjamin Crinquand, Benoît Cerutti, Guillaume Dubus

The recent detection of gravitational waves associated with a binary neutron star merger revives interest in interacting pulsar magnetospheres. Current models predict that a signif…
