Gravitational wave astronomy is revolutionizing our understanding of the Universe. Since the historic discovery of GW150914 in 2015, ground-based interferometers have discovered over 90 compact binary coalescence events. Meanwhile, pulsar timing arrays are being exploited to search for gravitational waves with periods of years to decades. After several decades of international efforts, we may be finally approaching the sensitivity to detect waves from supermassive binary black holes. In this talk, I will summarize recent progresses and future prospects of gravitational wave astronomy in the nanohertz frequency band, with a focus on latest results from the Parkes Pulsar Timing Array.
Dr ZHU Xingjiang is a faculty member at the Advanced Institute of Natural Sciences, Beijing Normal University (Zhuhai). He was an OzGrav Research Fellow (2017 - 21) at the School of Physics and Astronomy, Monash University, Australia. Prior to that, he was first a PhD student (2011-15) and then a Research Associate (2015-17) at The University of Western Australia.Dr Zhu's research interests include gravitational-wave astrophysics, pulsars and data analysis. He has been a member of the Parkes Pulsar Timing Array project since 2013, and was a member of the LIGO Scientific Collaboration (2012-2021). During 2019-2020, he served on the steering committee for the International Pulsar Timing Array collaboration. Dr Zhu currently serves on the KAGRA Scientific Congress (KSC) board.
