IAS Fundamental Physics Seminar Series - Primordial Black Hole Mergers as a Cosmological Probe
2:00pm - 3:00pm
IAS 4042, 4/F, Lo Ka Chung Building, Lee Shau Kee Campus, HKUST
Abstract
Since the detection of the first gravitational wave (GW) event GW150914, the primordial black hole (PBH) scenario is a potential explanation for the merger rate of detected GW events in LVK. In this talk, the speaker will discuss the future perspectives of PBH merger rate as a cosmological probe in next-generation GW detectors. By using the PBH merger rate population and its evolution in redshift space, it can help study cosmology on background level: tracking the history of cosmic expansion, and first order level: structure growth and dark matter distribution.
