Optimizing the hybrid parallelization of BHAC

Salvatore Cielo, Oliver Porth, Luigi Iapichino +3

We present our experience with the modernization on the GR-MHD code BHAC, aimed at improving its novel hybrid (MPI+OpenMP) parallelization scheme. In doing so, we showcase the use…

The Polarized Image of a Synchrotron Emitting Ring of Gas Orbiting a Black Hole

Ramesh Narayan, Daniel C. M. Palumbo, Michael D. Johnson +237

Synchrotron radiation from hot gas near a black hole results in a polarized image. The image polarization is determined by effects including the orientation of the magnetic field i…
