3D particle-in-cell simulations of pulsar wind-disk interaction: application to the transitional millisecond pulsar PSR J1023+0038
Valentina Richard-Romei, Benoît Cerutti, Alessandro Papitto +1
Transitional millisecond pulsars constitute a peculiar subclass of neutron stars in which the pulsar alternates between accretion-powered and rotation-powered states, depending on…
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…
Effect of magnetic field inclination on black hole jet power and particle acceleration
Enzo Figueiredo, Benoît Cerutti, Kyle Parfrey
Rotating black holes are known to launch relativistic jets and accelerate particles provided they accrete a magnetized plasma. However, it remains unclear how the global magnetic f…
Particle Acceleration in Collisionless Magnetically Arrested Disks
Jesse Vos, Benoit Cerutti, Monika Moscibrodzka +1
We present the first collisionless realization of two-dimensional axisymmetric black hole accretion consistent with a persistent magnetically arrested disk state. The accretion flo…
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…
Relativistic reconnection with effective resistivity: I. Dynamics and reconnection rate
M. Bugli, E. F. Lopresti, E. Figueiredo +6
Relativistic magnetic reconnection is one of the most fundamental mechanisms considered responsible for the acceleration of relativistic particles in astrophysical jets and magneto…
