The far-ultraviolet spectroscopy of molecules of astrophysical interest
… of such molecules will lead to a better understanding of their astrophysical behaviour, in particular Celestial Masers. This thesis is preoccupied with the spectroscopy of H$_{2}$O, D$_{2}$O, OH, CO, and C$_{2}$H$_{2}$ in the region 1200$\AA$-400$\AA$ and absolute absorption coefficients are …

Gravitational waves: understanding black holes
… observations of gravitational waves as tools for astronomy and fundamental physics. Gravitational waves are small ripples in spacetime produced by rapidly accelerating masses; their existence has been predicted for almost 100 years, but the first direct evidence of their existence came only very …

The power spectrum and bispectrum of inflation and cosmic defects
… such as the bispectrum, are required to test and constrain such models. The late-time distribution of matter in the Universe - large-scale structure (LSS) - contains much more information than the CMB that has not yet been used. In this thesis, we look at both problems: the effects of cosmic …
