This week we will have Yu Jiming (俞继铭) to present his recent work, at 7PM Dec. 03 (Tuesday) in the 19th-floor Observatory Hall.

Title: Constraining Hubble Constant with Gravitational Wave Detectors

Abstract: The discovery of GW signals, produced by the coalescence of stellar-mass binary black holes (SBBHs), opens a new window to study the astrophysical origins and dynamical evolutions of compact binaries. In addition, these GW events can be treated as the standard sirens to constrain various cosmological parameters such as the Hubble constant. He will talk his work about investigating the potential constraint on the Hubble constant H0 by SBBHs, if their redshift information is extracted from the candidates of host galaxy groups.

You are welcome to join the discussion. We will provide snacks and drinks.
