Reconstructing the EFT of Inflation from Cosmological Data

Amel Durakovic, Paul Hunt, Subodh P. Patil +1

Reconstructions of the primordial power spectrum (PPS) of curvature perturbations from cosmic microwave background anisotropies and large-scale structure data suggest that the usua…

Reconstruction of a direction-dependent primordial power spectrum from Planck CMB data

Amel Durakovic, Paul Hunt, Suvodip Mukherjee +2

We consider the possibility that the primordial curvature perturbation is direction-dependent. To first order this is parameterised by a quadrupolar modulation of the power spectru…

Search for features in the spectrum of primordial perturbations using Planck and other datasets

Paul Hunt, Subir Sarkar

We reconstruct the power spectrum of primordial curvature perturbations by applying a well-validated non-parametric technique employing Tikhonov regularisation to the first data re…

Reconstruction of the primordial power spectrum of curvature perturbations using multiple data sets

Paul Hunt, Subir Sarkar

Detailed knowledge of the primordial power spectrum of curvature perturbations is essential both in order to elucidate the physical mechanism (`inflation') which generated it, and…

Constraints on large scale inhomogeneities from WMAP-5 and SDSS: confrontation with recent observations

Paul Hunt, Subir Sarkar

Measurements of the SNe Ia Hubble diagram which suggest that the universe is accelerating due to the effect of dark energy may be biased because we are located in a 200-300 Mpc und…

Multiple inflation and the WMAP 'glitches' II. Data analysis and cosmological parameter extraction

Paul Hunt, Subir Sarkar

Detailed analyses of the WMAP data indicate possible oscillatory features in the primordial curvature perturbation, which moreover appears to be suppressed beyond the present Hubbl…

Multiple inflation and the WMAP 'glitches'

Paul Hunt, Subir Sarkar

Observations of anisotropies in the cosmic microwave background by the Wilkinson Microwave Anisotropy Probe suggest the possibility of oscillations in the primordial density pertur…
