Daryl Haggard’s research focuses on Sagittarius A*, the supermassive black hole at the heart of our Milky Way Galaxy. Haggard’s team uses radio, submillimeter, near infrared, and X-ray telescopes to probe the black hole’s exotic environment, where strong gravity plays a key role. Her team studies the interplay between distant growing supermassive black holes, or active galactic nuclei, and their host galaxies. They have also searched for X-ray flashes emitted from neutron stars and black holes when they collide.
