Dr. Alessandra Corsi received her Laurea in Physics in 2003 and her Ph.D. in Astronomy in 2007 from the University of Rome Sapienza. She carried out post-doctoral research at various institutions including the Pennsylvania State University and the California Institute of Technology. Since 2014 she is an Assistant Professor in the Department of Physics and Astronomy at Texas Tech University. Her research focuses on time-domain astronomy, with emphasis on relativistic transients and gravitational wave physics. In 2015 she received an NSF CAREER award titled “CAREER: Radio and gravitational-wave emission from the largest explosions since the Big Bang”.

Abstract

When a pair of superdense neutron stars collided in a galaxy 130 million light-years from Earth, an event dubbed GW170817, they unleashed not only a train of gravitational waves but also photons at all wavelengths, including an ongoing torrent of radio waves. In this talk, I will review the fantastic story of GW170817, emphasizing the observations carried out in radio with the Karl G. Jansky Very Large Array. I will conclude highlighting the impact that this discovery has on the future of multi-messenger astronomy.
