Modified gravity and massive neutrinos: constraints from the full shape analysis of BOSS galaxies and forecasts for Stage IV surveys
Chiara Moretti, Maria Tsedrik, Pedro Carrilho +1
We constrain the growth index by performing a full-shape analysis of the power spectrum multipoles measured from the BOSS DR12 data. We adopt a theoretical model based on the E…
Cosmology with the EFTofLSS and BOSS: dark energy constraints and a note on priors
Pedro Carrilho, Chiara Moretti, Alkistis Pourtsidou
We analyse the BOSS DR12 galaxy power spectrum data jointly with BAO data for three models of dark energy. We use recent measurements using a windowless estimator, and an independe…
Interacting dark energy from the joint analysis of the power spectrum and bispectrum multipoles with the EFTofLSS
Maria Tsedrik, Chiara Moretti, Pedro Carrilho +2
Interacting dark energy models have been suggested as alternatives to the standard cosmological model, CDM. We focus on a phenomenologically interesting class of dark scattering…
On the road to percent accuracy VI: the nonlinear power spectrum for interacting dark energy with baryonic feedback and massive neutrinos
Pedro Carrilho, Karim Carrion, Benjamin Bose +4
Understanding nonlinear structure formation is crucial for fully exploring the data generated by stage IV surveys, requiring accurate modelling of the power spectrum. This is chall…
Non-Gaussianity in inflationary scenarios for primordial black holes
Matthew W. Davies, Pedro Carrilho, David J. Mulryne
Working in an idealised framework in which a series of phases of evolution defined by the second slow-roll parameter are matched together, we calculate the reduced bispectrum,…
Interacting dark energy from redshift-space galaxy clustering
Pedro Carrilho, Chiara Moretti, Benjamin Bose +2
Interacting dark energy models have been proposed as attractive alternatives to CDM. Forthcoming Stage-IV galaxy clustering surveys will constrain these models, but they require…
The intrinsic bispectrum of the CMB from isocurvature initial conditions
Pedro Carrilho, Karim A. Malik
Non-linear effects in the early Universe generate non-zero bispectra of the cosmic microwave background (CMB) temperature and polarization, even in the absence of primordial non-Ga…
Non-Gaussianity after many-field reheating
Pedro Carrilho, David Mulryne, John Ronayne
We numerically investigate reheating after quadratic inflation with up to 65 fields, focusing on the production of non-Gaussianity. We consider several sets of initial conditions,…
Dissecting the growth of the power spectrum for primordial black holes
Pedro Carrilho, Karim A. Malik, David J. Mulryne
We consider the steepest rate at which the power spectrum from single field inflation can grow, with the aim of providing a simple explanation for the growth found recently.…
Magnetogenesis from isocurvature initial conditions
Pedro Carrilho, Karim A. Malik
The generation of magnetic fields is a natural consequence of the existence of vortical currents in the pre-recombination era. This has been confirmed in detail for the case of adi…
Attractor Behaviour in Multifield Inflation
Pedro Carrilho, David Mulryne, John Ronayne +1
We study multifield inflation in scenarios where the fields are coupled non-minimally to gravity via , where are coupling constants, the fields…
Isocurvature initial conditions for second order Boltzmann solvers
Pedro Carrilho, Karim A. Malik
We study how to set the initial evolution of general cosmological fluctuations at second order, after neutrino decoupling. We compute approximate initial solutions for the transfer…
Vector and tensor contributions to the curvature perturbation at second order
Pedro Carrilho, Karim A. Malik
We derive the evolution equation for the second order curvature perturbation using standard techniques of cosmological perturbation theory. We do this for different definitions of…
