Abstract (摘要): Einstein's theory of general relativity was proposed over 100 years ago and has successfully passed a large number of observational tests in weak gravitational fields. However, the strong field regime is still largely unexplored, and there are many modified and alternative theories that have the same predictions as Einstein's gravity for weak fields and present deviations only when gravity becomes strong. X-ray reflection spectroscopy is potentially a powerful tool for testing the strong gravity region around astrophysical black holes with electromagnetic radiation. In this talk, I will present the reflection model RELXILL_NK designed for testing the metric around black holes and the current constraints on possible new physics from the analysis of a few sources.
Short Bio (报告人简介): Cosimo Bambi is currently Xie Xide Junior Chair Professor (谢希德青年教授) at the Department of Physics at Fudan University. He received the Laurea degree from Florence University in 2003 and the PhD degree from Ferrara University in 2007. He was appointed as a postdoc at IPMU/The University of Tokyo (Japan) and at LMU Munich (Germany). He joined Fudan University at the end of 2012 under the 1000 Young Talents Program (青年千人计划). His main research interests focuses on black holes and observational tests of gravity models. He has published more than 130 papers on high impact factor refereed journals as first or corresponding author, he has over 3,700 citations and his h-index is 37. He has received a number of awards, including the 2018 Magnolia Silver Award (上海市白玉兰纪念奖) for outstanding contributions to Shanghai's development and the Xu Guangqi Prize as the best Italian scholar in China.
