Andrew MacFadyen

Andrew MacFadyen is a Professor of Physics at New York University, affiliated with the Department of PHY. His research focuses on astrophysics and cosmology, particularly within the Center for Cosmology and Particle Physics. His work includes models of the explosive death of massive stars, the growth of black holes from stellar collapse, and the dynamics of astrophysical environments involving strong shock waves, ultra-relativistic speeds, magnetic fields, and neutrino emission. He develops computational tools to simulate these phenomena, contributing to studies on gamma-ray bursts, supernovae, and binary massive black holes. His publications include research on collapsars, relativistic hydrodynamics codes, and circumbinary accretion disks.

Andrew MacFadyen is an astrophysicist at New York University, specializing in the study of gamma-ray bursts (GRBs), collapsars, and relativistic jets. His research explores the connection between GRBs and supernovae, particularly focusing on 'failed supernovae' and the mechanisms behind gamma-ray burst afterglows. He investigates the dynamics of relativistic jets in collapsars, the role of binary systems in accretion processes, and the electromagnetic counterparts of gravitational wave events such as GW170817. His work also includes the study of circumbinary disks, binary black hole mergers, and the formation of massive black hole binaries. MacFadyen's research integrates numerical simulations and observational data to understand high-energy astrophysical phenomena.
