Electron Heating in Low Mach Number Perpendicular shocks. I. Heating Mechanism
Xinyi Guo, Lorenzo Sironi, Ramesh Narayan
Recent X-ray observations of merger shocks in galaxy clusters have shown that the post-shock plasma is two-temperature, with the protons hotter than the electrons. By means of two-…
Electron and proton heating in trans-relativistic magnetic reconnection
Michael E. Rowan, Lorenzo Sironi, Ramesh Narayan
Hot collisionless accretion flows, such as the one in Sgr A at our Galactic center, provide a unique setting for the investigation of magnetic reconnection. Here, protons are…
Numerical simulations of the Cosmic Battery in accretion flows around astrophysical black holes
Ioannis Contopoulos, Antonios Nathanail, Alexander Sadowski +2
We implement the KORAL code to perform two sets of very long general relativistic radiation magnetohydrodynamic simulations of an axisymmetric optically thin magnetized flow around…
Optical and X-ray luminosity of expanding nebulae around ultraluminous X-ray sources
Magdalena Siwek, Aleksander Sadowski, Ramesh Narayan +2
We have performed a set of simulations of expanding, spherically symmetric nebulae inflated by winds from accreting black holes in ultraluminous X-ray sources (ULXs). We implemente…
