Constraining alternative theories of gravity using GW and GW
Mariafelicia De Laurentis, Oliver Porth, Luke Bovard +2
The recently reported gravitational wave events GW and GW caused by the mergers of binary black holes [arXiv:1602.03841],[arXiv:1606.04855],[arXiv:1606.04856] provi…
Reconnection and particle acceleration in interacting flux ropes I. Magnetohydrodynamics and test particles in 2.5D
Bart Ripperda, Oliver Porth, Chun Xia +1
Magnetic reconnection and non-thermal particle distributions associated with current-driven instabilities are investigated by means of resistive magnetohydrodynamics (MHD) simulati…
The Black Hole Accretion Code
Oliver Porth, Hector Olivares, Yosuke Mizuno +5
We present the black hole accretion code (BHAC), a new multidimensional general-relativistic magnetohydrodynamics module for the MPI-AMRVAC framework. BHAC has been designed to sol…
BlackHoleCam: fundamental physics of the Galactic center
C. Goddi, H. Falcke, M. Kramer +36
Einstein's General Theory of Relativity (GR) successfully describes gravity. The most fundamental predictions of GR are black holes (BHs), but in spite of many convincing BH candid…
Simulations of recoiling black holes: adaptive mesh refinement and radiative transfer
Zakaria Meliani, Yosuke Mizuno, Hector Olivares +3
(Abridged) We here continue our effort to model the behaviour of matter when orbiting or accreting onto a generic black hole by developing a new numerical code employing advanced t…
Diffusion in Pulsar Wind Nebulae: An Investigation using Magnetohydrodynamic and Particle Transport Models
O. Porth, M. J. Vorster, M. Lyutikov +1
We study the transport of high-energy particles in pulsar wind nebulae (PWN) using three-dimensional MHD (see Porth et al. (2014) for details) and test-particle simulations, as wel…
Particle acceleration in explosive relativistic reconnection events and Crab Nebula gamma-ray flares
Maxim Lyutikov, Lorenzo Sironi, Sergey Komissarov +1
We develop a model of particle acceleration in explosive reconnection events in relativistic magnetically-dominated plasmas and apply it to explain gamma-ray flares from the Crab N…
