Add to Calendar 10/10/2018 4:00 pm 10/10/2018 America/Chicago Physics Colloquium: “Dawn of gravitational-wave astronomy: from Planck to Hubble” DESCRIPTION:

Abstract: In September 2015, LIGO detectors in Hanford and Livingston in the US made the spectacular discovery, in gravitational waves, of two black holes at a distance of 1.3 billion light years spiraling in towards each other and merging in less than 200 milliseconds. In August 2017, the LIGO detectors together with the Virgo detector in Pisa, Italy, discovered the inspiral and merger of a pair of neutron stars at a distance of 130 million light years. These discoveries have ushered in a new era in observational astronomy, fundamental physics, and cosmology. I will describe how gravitational-wave observations over the past three years have helped in testing the dynamics of black hole horizons measuring the equation of state of dense nuclear matter, and providing a new tool for measuring the Hubble constant. I will conclude with a discussion of future prospects in gravitational-wave astronomy including LIGO-India, Laser Interferometer Space Antenna, Einstein Telescope and Cosmic Explorer.
