Abstract

摘要

The first detection of gravitational waves from binary black hole merger in September 2015 not only confirmed Einstein's 1915 general theory of relativity, but also marked the beginning of a new era of gravitational wave astronomy. In recognition of the promising revolutionary effect of this discovery, the 2017 Nobel Prize in Physics was awarded to the three pioneers in the field,  Rainer Weiss (MIT), Kip Thorne and Barry Barish (Caltech).  In August 2017, the world was excited again by a new breakthrough: the first detection of gravitational waves from binary neutron star merger.  Moreover,  over 70 observatories in the world have detected the electromagnetic counterparts associated with this source. This marked the beginning of the multi-messenger astronomy including gravitational waves and is considered by many as revolutionary as the first detection.   The Gravitational Wave Astronomy group at the University of Western Australia is part of the international effort in detecting gravitational waves.  The group has participated in the online searches leading to the discoveries from the LIGO-Virgo gravitational wave observatories.  In this seminar, I will present our effort in real-time detection and localization and in early warnings of gravitational waves from binary coalescence.  I will also discuss the capacity of the future 3rd-generation gravitational wave detectors in terms of source localization and its implication to cosmology.
