When two neutron stars or a neutron star and a black hole merge, the extreme energy release launches ultra-relativistic jets and creates ripples in space-time. We can detect these even from vast distances as short gamma-ray bursts (GRBs) and gravitational-waves! The intense pressure of the merger allows very heavy elements to form (events like these are likely the main production sites of gold and platinum in the universe). We detect the radioactive glow of these newly-formed heavy elements as a ‘kilonova’. I use the combined ‘multi-messenger’ information from short GRBs, kilonovae, and gravitational-waves to learn about our universe, including just how influential mergers are in producing gold, and how matter behaves in extreme gravity.
I received my PhD from the University of Leicester in 2015. The title of my PhD thesis was “The Progenitors of Extended Emission Gamma-Ray Bursts”. My supervisors were Professor Paul O’Brien and Professor Graham Wynn.
After receiving my PhD, I spent two years between June 2015 and August 2017 as a postdoctoral research associate at Space Telescope Science Institute in Baltimore, USA, where I worked with Dr Andy Fruchter. I moved to The University of Warwick in September 2017 to work with Professor Andrew Levan. I joined the Institute of Gravitational Wave Astronomy in April 2021 to become part of Dr Matt Nicholl‘s time domain research group at Birmingham. I became an Assistant Professor in the School of Physics and Astronomy in September 2022. I am a member of a number of transient hunting collaborations and consortia. These include:
