In this talk, I will briefly summarize recent progresses and future prospects of gravitational wave astronomy on both short and long timescales, whilefocusingon the study of binary neutron stars andsupermassive binary black holes. After several decades of international efforts,wemay be finally approaching the sensitivity to detect waves from supermassive binary black holes. Meanwhile, pulsar timing arrays arebeingexploitedto search for gravitational waves with periods of years to decades. These events, lasting from fractions of seconds to minutes, include stellar-mass binary black holes, binary neutron stars and neutron star-black hole binaries. Since the historic discovery of GW150914 in 2015,ground-based interferometershave discoveredover 90 compact binarycoalescence events. 报告摘要: Gravitational wave astronomy is revolutionizing our understanding of the Universe.
