Andrew MacFadyen

Professor Of Physics

Areas of Research/Interest

I work on models of the explosive death of massive stars and on the growth of black holes from stellar collapse and at the centers of galaxies. I make use of parallel computers to simulate the flow of gas in astrophysical environments where strong shock waves, ultra-relativistic speeds, and magnetic fields as well as neutrino emission and nuclear reactions are important.
