MHDuet : a high-order General Relativistic Radiation MHD code for CPU and GPU architectures
Carlos Palenzuela, Miguel Bezares, Steven Liebling +12
We present MHDuet, an open source evolution code for general relativistic magnetohydrodynamics with neutrino transport. The code solves the full set of Einstein equations coupled t…

Black hole mimickers: from theory to observation
Cosimo Bambi, Ramy Brustein, Vitor Cardoso +16
The black hole paradigm, while remarkably successful, raises fundamental questions-both classical and quantum-about the nature of spacetime, horizons, and singularities. Black hole…

Implications of Magnetic Flux-Disk Mass Correlation in Black Hole-Neutron Star Mergers for GRB sub-populations
Manuel R. Izquierdo, Carlos Palenzuela, Steven Liebling +2
We perform numerical relativity simulations of black hole-neutron star (BH-NS) mergers with a fixed mass ratio of , varying the BH spin to produce a wide range of post-merge…
