Gravitational waves are ripples in spacetime, produced by the most violent events in the cosmos: exploding stars, colliding black holes, perhaps even the Big Bang itself. In this lecture, I will review the latest LIGO and Virgo observations of the mergers of binary black holes and neutron stars – and how these observations are shaping and improving our understanding of strong gravity, cosmology，and fundamental physics.I will then outline the gravitational-wave“roadmap”for the coming decades, including the planned LIGO and Virgo observing runs and upgrades, the addition of KAGRA and LIGO India to the ground-based network, the “ third-generation” ground-based interferometers proposed for the2030s and the enormous potential of spaceborne detectors that will probe the lower frequency gravitational-wave spectrum. I will describe how these observations should provide a much deeper and more complete view of the Gravitational Universe over the next two decades, offering new and complementary insights into a wide range of astrophysical questions– from the origin of black holes and the evolution of galaxies to the nature of dark matter and dark energy and perhaps even the fundamental properties of spacetime itself. |

Martin Hendry is Professor of Gravitational Astrophysics and Cosmology at the University of Glasgow, where he is currently Head of the School of Physics and Astronomy. He is a senior member of the LIGO Scientific Collaboration (LSC), serving on the LSC Management Team and chairing the LSCEducation and Public Outreach Group. Since 2015 he has played a leading role in planning and supporting the major LIGO and Virgo press announcements and press conferences about gravitational-wave discoveries, as well as managing the LSC’svarious social media platforms. He also co-chairs the global Advocacy and outreach working group of the recently formed LISA Consortium.
Before moving into gravitational-wave astronomy, Martin’s early research work was mainly in galaxy surveys and the cosmic distance scale – with the common theme of developing new and powerful Bayesian analysis methods. His main current research interests are in multi-messenger cosmology using “standard sirens”. Heis a Fellow of the Institute of Physics, the Royal Astronomical Society and theRoyal Society of Edinburgh. |
