I am a PhD student in the Astronomy and Astrophysics group at the University of Warwick. My supervisor is Prof. Andrew Levan.


In the past decade wide field sky surveys have unearthed a new subclass of supernova events, so called Superluminous Supernovae (SLSNe). These transient events are approximately 100 times brighter than standard core collapse supernovae events, and their peak luminosities can span tens of days. While SLSNe are thought to arise from deaths of the most massive stars, the mechanisms through which their extreme luminosities and duration are achieved are still the subject of much debate. Possible mechanisms include:

  • Pair instability supernovae - the collapse of a massive carbon-oxygen stellar core due to the annihilation of electron positron pairs produced at high temperatures
  • An interaction between the explosion ejecta and a dense circumstellar envelope of material surrounding the star
  • An injection of energy from an internal engine, such as the energy released from the spin down of a magnetar

My work involves studying the host galaxies of these events and using their properties to infer further information about the progenitors of SLSNe.
