Primordial Black Hole Mergers as a Cosmological Probe

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.


About the Speaker

Dr. DING Qianhang is currently a postdoctoral researcher in the Center for Theoretical Physics of the Universe (CGA Group) in the Institute for Basic Science (South Korea). He obtained his PhD in Physics from The Hong Kong University of Science and Technology in 2023. Dr. Ding mainly works on gravitational wave cosmology, and uses gravitational wave as a probe to understand the fundamental physics in cosmology, such as cosmic tensions in Lambda-CDM model, the property of dark universe.
