Gregory Ashton

What's the talk about?

Late in 1915 Einstein presented the final form of his theory of gravity: General Relativity. This description of nature has so far stood the test of countless rigorous tests and has led to many new insights from exotic black-holes to the shape of the universe itself.

However, advances in technology and our understanding of astrophysics led to the establishment of an international collaboration LIGO/Virgo which built a gravitational wave detector and announced the first detection in February 2016 (https://www.ligo.caltech.edu/detection). This event, the final seconds of a merger between two black holes, marks a new era of gravitational wave astronomy.

In this talk Greg will discuss the historical significance of Einstein's General Relativity, the relevance of gravitational waves and their potential, and describe the current status of the LIGO/Virgo detectors.


Greg Ashton is a postdoctoral researcher at the Albert Einstein Institute for gravitational wave physics in Hannover, Germany having recently finished his PhD at the University of Southampton. He specialises in the physics of neutron stars and the data analysis of detecting continuous gravitational waves.
