The Institute for Subatomic Physics at Utrecht University invites applications for two PhD studentships in gravitational wave data analysis and phenomenology. As the successful candidate you will work in the gravitational waves group of Professor Chris Van Den Broeck and Dr. Sarah Caudill, on gravitational wave observations of coalescing binary neutron stars and black holes, with a view on probing the nature of compact objects and determining a neutron star’s interior structure. You will both be members of the Virgo Collaboration, which together with the LIGO Scientific Collaboration jointly analyses all data from the LIGO and Virgo interferometers. The group is also part of the LISA Consortium, and has been heavily involved in developing the science case for third-generation gravitational wave detectors such as Cosmic Explorer and Einstein Telescope.
