Gold, Roman

My research is centered around nature's most compact objects, black holes and neutron stars, in particular their observational appearance in the form of gravitational waves or electromagnetic emission.

In my work I push the boundaries to provide explicit theoretical model predictions (gravitational waveforms, predicted radio images, polarization signatures, etc), as well as advance our ability to compare these theoretical predictions to cutting-edge observations taken by the Event Horizon Telescope. Through such comparisons, which typically require high-performance computing, I seek to advance our understanding of highly energetic astrophysical processes as well as refining our understanding of gravity, the nature of black holes and our universe as a whole. The first image of the black hole shadow in M87* is not the culmination but only the beginning of a new era of black hole astrophysics.
