On the 14th of September 2015, the Advanced LIGO gravitational wave detector made the first detection of gravitational waves. The observed signal, which originated from the coalescence and merger of two binary black holes, heralded the dawn of gravitational wave astronomy. Since then, gravitational waves from several more binary black hole coalescences have been detected by Advanced LIGO and Advanced Virgo. This talk will give a brief overview of gravitational waves as well as the Advanced LIGO and Advanced Virgo gravitational wave detectors before describing the multiple detections of gravitational waves. The properties of the observed signals will be presented and the implications of these detections discussed. Finally, prospects for binary neutron star detections and multi-messenger astronomy, which combine gravitational wave observations with gamma-ray, X-ray, optical, etc. observations, are discussed. |

Ik Siong Heng教授:
2017 – present: Professor of Gravitational Wave Astrophysics, University of Glasgow
2013 – 2017: Reader, University of Glasgow
2005 – 2013: Lecturer, University of Glasgow
2002 – 2005: Postdoctoral researcher, Max Planck Institute for Gravitational Physics, Hannover, Germany
2000 – 2002: Postdoctoral researcher, Louisiana State University
2013 – present co-Chair of the Burst Analysis Group and member of Data Analysis Council, LIGO
2005 – present Member of LIGO Scientific Collaboration council
Prof. Heng is a world-leading scientist and a prominent member of the LIGO Scientific Collaboration (LSC), an international collaboration of over 1000 scientists which operates the LIGO (USA) and GEO 600 (UK-German) detectors. As elected co-chair of the LSC ‘Burst’ group, which was the first analysis to detect the gravitational wave signal (GW150914), he steered the global team on the analysis of the detection and contributed to the detection paper. Additionally, he co-lead the companion paper describing the analysis that made the first discovery. Prof. Heng has over 170 publications in high impact journals, with a career h-index of 53, as well as over 40 invited talks and presentations at international conferences. |
