Astrophysics Colloquium Intermediate-mass Black Holes in the Era of Gravitational-wave Astronomy Presented by Karan Jani Vanderbilt University Thursday, October 10, 2019 11:00 A.M. in 169-336 and on Webex Abstract The direct measurement of gravitational waves is a powerful tool for surveying the population of black holes across the universe. The first gravitational-wave catalog from LIGO has showcased mergers of binary black holes as heavy as 90 solar masses since half the current age of the universe. However, there is yet no unambiguous evidence of black holes or their binaries in the intermediate-mass range of 100-100,000 solar masses. In this talk, I will provide an overview of our search for intermediate-mass black holes in LIGO data and the promise these elusive sources holds for all the next-generation gravitational-wave detectors, including LISA. Further, I would highlight their unique prospect for multi-wavelength gravitational-wave astronomy and tests of general relativity.
