Collisionless Accretion of Finite-Angular-Momentum Plasma onto a Spinning Black Hole
John M. Mehlhaff, Alexander Y. Chen, Martin Luepker +1
In low-luminosity active galactic nuclei like M87* and Sgr A*, the accretion disk around the central supermassive black hole is tenuous and collisionless. As a result, the usual id…
Emergence of cyclic flux eruptions in kinetic simulations of magnetized spherical accretion onto a Schwarzschild black hole
Enzo Figueiredo, John Mehlhaff, Adrien Soudais +1
The dynamics of black hole magnetospheres critically depend on the black hole spin and on the structure of the accretion flow. In the limit of a Schwarzschild black hole immersed i…
Radiative relativistic turbulence as an in situ pair-plasma source in blazar jets
John Mehlhaff, Muni Zhou, Vladimir Zhdankin
As powerful gamma-ray engines, blazars -- relativistic plasma jets launched toward Earth from active galactic nuclei -- are manifestly high-energy particle accelerators. Yet, exact…
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…
Composition-asymmetric and sheared relativistic magnetic reconnection
Enzo Figueiredo, Benoît Cerutti, John Mehlhaff +1
Relativistic magnetic reconnection studies have focused on symmetric configurations so far, where the upstream plasma has identical properties on each side of the layer. The bounda…
Kinetic simulations and gamma-ray signatures of Klein-Nishina relativistic magnetic reconnection
J. Mehlhaff, G. Werner, B. Cerutti +2
Black hole and neutron star environments often comprise collisionless plasmas immersed in strong magnetic fields and intense baths of low-frequency radiation. In such conditions, r…
Pair-Regulated Klein-Nishina Relativistic Magnetic Reconnection with Applications to Blazars and Accreting Black Holes
J. M. Mehlhaff, G. R. Werner, D. A. Uzdensky +1
Relativistic magnetic reconnection is a powerful agent through which magnetic energy can be tapped in astrophysics, energizing particles that then produce observed radiation. In so…
