About me


I am a Royal Astronomical Society Research Fellow and Lecturer (Assistant Professor) at the University of Birmingham, UK. I am also Principal Investigator of the KRANK project, funded by the European Research Council.

I study the dynamic sky: transient and explosive phenomena that evolve on human timescales. Or simply put, stars exploding, colliding, disrupting and generally having a bad time.

I am most interested in how compact objects — neutron stars and black holes — provide the engines behind some of the rarest and most powerful events in the Universe. These include:

  • Superluminous supernovae, which for a year emit as much light as the entire Milky Way Galaxy. These super-duper-novae can provide a unique window into the evolution and fate of some of the most massive stars ever to have lived and died.
  • Tidal disruption events caused by stars passing too close to black holes with a million times the mass of our Sun. The energy released when these stars are shredded can teach us black holes and matter behave in extreme gravity.
  • Kilonovae powered by collisions between two neutron stars or a neutron star and a black hole. These collisions are so powerful they can be detected by the ripples they make in spacetime, via gravitational waves. They also likely produce all the gold in the Universe.

The goal of my current project is to find and study samples of these rare events using large surveys such as the Vera Rubin Observatory Legacy Survey of Space and Time alongside machine learning approaches to source identification.

Researchers tend to move around. Before joining UoB, I have worked or studied at the University of Edinburgh, Harvard University, Queen’s University Belfast, and Oxford University. Finally, Nickel-56 is a very important radioactive nucleus produced in supernova explosions, hence my twitter handle: @mattnicholl56!
