Profile

I am a PhD student supervised by Prof Chris Clarkson.

Project title: Integrated effects in Large-Scale Structure

In previous studies, integrated effects, such as lensing, Shapiro time delay and integrated Sachs-Wolfe, have largely been ignored in Fourier power spectrum analysis. During this project, we developed a method to calculate the contribution to the power spectrum arising from integrated effects and show that, if we don’t include these effects in our analysis, it can heavily bias our measurements of primordial non-Gaussianity. I will continue this work and expand it to calculate the integrated matter bispectrum and also potentially to a P(k) Fourier analysis of shear cross shear.
