Or Graur

I'm an Associate Professor at the Institute of Cosmology and Gravitation at the University of Portsmouth. I am also a research associate at the American Museum of Natural History in New York. I study different types of transients - astrophysical phenomena that change on human timescales. I mostly work on supernovae - the explosions of stars - and try to figure out which stars explode as different types of supernovae. To do so, I use images and spectra of the supernovae and their host galaxies.
