Plasma flow in force-free magnetospheres: two-fluid model near pulsars and black holes
Morifumi Mizuno, Samuel E. Gralla, Alexander Philippov
Force-free electrodynamics describes the electromagnetic field of the magnetically dominated plasma found near pulsars and active black holes, but gives no information about the un…
Wave-Mediated Boundary Layers of Accretion Discs: Role of Internal Structure of the Accretor
Samuel G. D. Turner, Roman R. Rafikov, Alexander A. Philippov
Disc accretion onto astrophysical objects with a material surface proceeds through the boundary layer (BL) -- a radially narrow region in the inner disc where the incoming gas must…
Origin of Pulsed Radio Emission from Magnetars
Shuzhe Zeng, Alexander Philippov, James Juno +2
Extended periods of radio pulsations have been observed for six magnetars, displaying characteristics different from those of ordinary pulsars. In this Letter, we argue that radio…
Reconnection-driven Flares in M87*: Proton-Synchrotron-powered GeV Emission
Hayk Hakobyan, Amir Levinson, Lorenzo Sironi +2
Magnetic reconnection in current layers that form intermittently in radiatively inefficient accretion flows onto black holes is a promising mechanism for particle acceleration and…
Magnetized Accretion onto Neutron Stars: from Photon-trapped to Neutrino-cooled Flows
Luciano Combi, Christopher Thompson, Daniel M. Siegel +2
When a neutron star (NS) intercepts gas from a non-degenerate star, e.g., in a tidal disruption event, a common-envelope phase, or the collapsing core of a massive star, photons be…
Modeling of lightcurves from reconnection-powered very high energy flares from M87*
Siddhant Solanki, Jordy Davelaar, Bart Ripperda +1
The black hole at the center of M87 is observed to flare regularly in the very high energy (VHE) band, with photon energies GeV. The rapid variability, which can be a…
