Members of the NASA Night Sky Network joined us on Wednesday, November 29 when Dr. Brian O'Reilly, LIGO senior scientist and Advanced LIGO run manager for LIGO Livingston, share with us the latest exciting observations by the gravitational wave observatories and what that means for the future of astronomy.

The era of gravitational wave astrophysics began with the direct detection of gravitational waves emitted during the merger of a binary black hole system on September 14th 2015. The era of multi-messenger astronomy driven by the detection of gravitational waves began on August 17th 2017 when the LIGO and Virgo collaborations observed the merger of a binary neutron star system. This merger was followed 2 seconds later by a short gamma-ray burst, which was detected by the Fermi and INTEGRAL satellites. Follow-up observations by more than 70 collaborations of astronomers succeeded in identifying the
merged object's afterglow over a wide range of electromagnetic wavelengths.

In this webinar, Dr. Brian O'Reilly will introduce us to the techniques that enable us to detect the very small perturbations in space-time caused by gravitational waves, discuss the published results and what we can expect from the next few years of observations.

About Dr. Brian O'Reilly
Dr. Brian O’Reilly is the Lead Scientist based at the LIGO Livingston Observatory in Louisiana. He received his BSc from Dublin City University, Dublin, Ireland, in 1987 and his PhD from Northwestern University in Evanston, IL in 1995. His background in is High Energy Physics, but in 2002 changed fields and joined the LIGO Laboratory. He was the installation lead for the Advanced LIGO upgrade and his current responsibilities include run management for their observation runs.
