Gravitational Wave Astrophysics with Pulsar Timing Arrays

This Ph.D. thesis from the University of Birmingham UK opens new research avenues in the use of Pulsar Timing Arrays (PTAs) to study populations of super-massive black hole binaries through gravitational-wave observations. Chiara Mingarelli''s work has shown for the first time that PTAs can yield information about the non-linear dynamics of the gravitational field. This is possible because PTAs ca...
