Abstract: There are a few dozens of black hole binaries and candidates identified to date in the Milky Way and nearby galaxies, which only occupies a tiny fraction of the predicted stellar-mass black hole population. In this talk, I will first discuss how to reliably measure the black hole mass in soft X-ray transients, taking Nova Muscae 1991 as a case study. Then I will talk about issues in the mass distribution of black holes (i.e., the mass gap), and potential biases in current way of identifying black hole binaries. The last part of the talk is about the survey projects I have been involved in, aiming to discover more types of black hole binaries in the Milky Way Galaxy.

CV: Prof. Jianfeng Wu earned his bachelor (2003) and master (2006) degrees from Tsinghua University. Then he moved to The Pennsylvania State University in USA, obtaining his PhD degree in 2012. He did postdoctoral research afterward at Harvard-Smithsonian Center for Astrophysics and University of Michigan. In 2017 he was selected by the national "Thousand Youth Talents" program and became a professor at Dept. of Astronomy in Xiamen University. His research area covers black holes across the mass scale, studying both physical properties of black holes (e.g., measurement of mass and spin) and their cosmological evolution (e.g., high-redshift quasars). He is specially interested in multiwavelength data analysis and large scale surveys.
