Astronomical Society Holds Lecture on ‘Black Holes’

The Astronomical Society of Greenwich will present Dr. Andrew MacFayden speaking on “How to see Black Holes” on Sunday, Oct. 15 at 3:30 p.m.

Black holes are now known to be abundant in the universe. Recently, merging binary black holes have been detected through their emission of gravitational waves by the LIGO detectors.

Dr. MacFadyen (Center for Cosmology and Particle Physics, NYU) will discuss these black hole mergers and their supermassive cousins, with masses of billions of suns, and show supercomputer simulations of their interaction with surrounding interstellar gas.

These supermassive black hole binary mergers may soon be detected by studying pulsars in our galaxy and by future space missions such as LISA. These discoveries are transforming astronomy and ushering in a new age of gravitational wave astronomy with many more exciting discoveries expected in the future.

The lecture takes place in the
Cole Auditorium
of Greenwich Library, 101 West Putnam Ave., and is open to the public. For more information, visit
