About

Rafaella Margutti uses observations from spacecraft, optical telescopes, and radio antennae to study the most violent stellar explosions and stellar collisions found in nature. 

Targets of her research include: catastrophic collisions among black holes and neutron stars, which are now detectable sources of gravitational waves; Stellar disruptions that happen when a star approaches the supermassive black hole of its own galaxy; and the most luminous stellar explosions, which are how black holes and neutron stars are formed. 

By observing these violent phenomena in real time across the electromagnetic spectrum, Margutti sheds new light on the processes that lead to neutron stars and black holes and on the processes that enrich our universe with heavy chemical elements.
