Surhud More，印度IUCAA天体物理中心教授，2005年本科毕业于印度理工，2009年在海德堡大学拿到天体物理博士学位，随后分别在芝加哥大学，日本东京大学IPMU做博士后，并拿到IPMU助理教授位置。2019年回到IUCAA任教授。主要研究方向为：弱引力透镜，星系团动力学，星系形成和演化。为HSC-SSP核心成员。Gravitational waves (GWs) from the inspiral of binary compact objects offer a one-step measurement of the luminosity distance to the event, which is essential for the measurement of the Hubble constant, H0, which characterizes the expansion rate of the Universe. However, unlike binary neutron stars, the inspiral of binary black holes is not expected to be accompanied by electromagnetic radiation and a subsequent determination of its redshift. Consequently, independent redshift measurements of such GW events are necessary to measure H0. I will present how one can use statistical techniques such as cross-correlation between GW events and galaxies to infer the Hubble constant. I will present curated galaxy catalogs from the photometric data from the DESI Imaging legacy surveys for this purpose. Finally I will also discuss a new Bayesian approach to infer H0 by measuring the overdensity of galaxies around individual binary black hole merger events in configuration space and the current precision of such measurements of the Hubble constant.
