The transformation of galaxies in groups and clusters

My research focuses on the role of galaxy environment in changing galaxies from blue, star forming spirals into red passive ellipticals. In particular, I am interested in the properties of ‘jellyfish galaxies’ – galaxies that are undergoing ram pressure stripping, where the gas is being removed from a galaxy as it enters the cluster.
I am investigating ways in which we can identify new jellyfish galaxies in large surveys, using morphological measures including their light profiles, and through citizen science projects. This will help to create large samples of jellyfish galaxies, to better understand how these rare objects form and evolve as they enter galaxy clusters.
