Title: Cosmology with the redshift space bispectrum.

Supervisor: Prof Chris Clarkson

Content: The standard analysis of cosmological surveys is to use the 2-point function in Fourier space - the power spectrum. However, we can access additional information (non-gaussian parts) by also considering the (3-point) bispectrum. To do this it is important to consider both relativistic and wide angle effects, which come into play on large scales.  Better understanding of these will potentially allow us not only to probe new parameters but will also enable the possible detection of hugely important signatures, like primordial non-gaussianity. This will all be possible with the next generation of cosmological surveys which will enter us into the era of precision cosmology.
