Hi I’m David Starkey, I’m a 24 year old PhD candidate at the University of St Andrews and I’m studying Physics.

I’m part of a study that searches for active galaxies. These are also known as quasars (although the term can denote a variety of objects). An active galaxy is a galaxy that shines very brightly – due to the presence of a black hole that is consuming enormous amounts of mass. The material being consumed by the black hole sort of bunches up and forms a spinning disk of matter called an accretion disk.
