Tara Murphy

Prof. Tara Murphy is an Australian Astrophysicist and CAASTRO (the ARC Centre of Excellence for All-sky Astrophysics) chief investigator working in the School of Physics at the University of Sydney.[1][2] Murphy led a group that first confirmed radio emissions from the 2017 Neutron Star Merger event which provided evidence for a global scientific announcement in the field of gravitational waves.[3]

Education

Murphy completed a Bachelor of Science at the University of Sydney and a PhD (Astrophysics) at the University of Edinburgh.[4]

Career

In 2013, Murphy co-founded a start-up company called Grok Learning with James Curran, Nicky Ringland and Tim Dawborn which is an online learning platform that teaches computing to school students.[4][5]

During the global effort to record the 2017 Neutron Star Merger,[6][7] Murphy led a group at the University of Sydney that confirmed the first radio signals of gravitational waves that were caused by two neutron stars colliding in a galaxy 130 million light-years from Earth. This discovery was made 15 days after these gravitational waves were first reported by an international team of scientists and astronomers.[3]

In 2019, Murphy and their PhD student gathered data using the CSIRO's Australia Telescope Compact Array at Narrabri in New South Wales to observe radio emissions created by a shockwave from a mysterious cosmic 'cow' explosion, and potential birth of a black hole. Their findings suggested that there was a magnetar at the core of the supernova, and that this event was different from the typical supernova as there was energy that continued to power the explosion allowing the 'cow' to inexplicably become brighter with time.[8]
