Effect of lensing non-Gaussianity on the CMB power spectra
Antony Lewis, Geraint Pratten
Observed CMB anisotropies are lensed, and the lensed power spectra can be calculated accurately assuming the lensing deflections are Gaussian. However, the lensing deflections are…
3D Weak Lensing: Modified Theories of Gravity
Geraint Pratten, Dipak Munshi, Patrick Valageas +1
Weak lensing (WL) promises to be a particularly sensitive probe of both the growth of large scale structure (LSS) as well as the fundamental relation between matter density perturb…
Galaxy Clustering in 3D and Modified Gravity Theories
Dipak Munshi, Geraint Pratten, Patrick Valageas +2
We study Modified Gravity (MG) theories by modelling the redshifted matter power spectrum in a spherical Fourier-Bessel (sFB) basis. We use a fully non-linear description of the re…
Reconstructing the Thermal Sunyaev-Zel'dovich Effect in 3D
Geraint Pratten, Dipak Munshi
The thermal Sunyaev-Zel'dovich (tSZ) effect measures the line-of-sight projection of the thermal pressure of free electrons and lacks any redshift information. By cross correlating…
Effects of Linear Redshift Space Distortions and Perturbation Theory on BAOs: A 3D Spherical Analysis
Geraint Pratten, Dipak Munshi
The Baryon Acoustic Oscillations (BAO) are features in the matter power spectrum on scales of order 100-150 h^{-1} Mpc that promise to be a powerful tool to constrain and test cosm…
Non-Gaussianity in Large Scale Structure and Minkowski Functionals
Geraint Pratten, Dipak Munshi
Minkowski Functionals (MFs) are topological statistics that have become one of many standard tools used for investigating the statistical properties of cosmological random fields.…
