Scalar perturbations of Schwarzschild black holes in modified gravity.
This thesis is concerned with the physics related to scalar perturbations in the Schwarzschild geometry that arise in modifed gravity theories. It has already been shown that the gravitational waves emitted from a ...
The C-Band All Sky Survey commissioning and data analysis.
The C-Band All Sky Survey (C-BASS) is a ground based radio survey that scans the entire sky in Stokes I, Q and U at a central frequency of 5 GHz with a 1 GHz bandwidth and an angular resolution of 0.73 . The experiment ...
Dynamics of radiating stars in the strong gravity regime.
We model the dynamics of a spherically symmetric radiating dynamical star, emitting outgoing null radiation, with three spacetime regions. The local internal atmosphere is a two-component system consisting of standard ...
