The skewness of the distance-redshift relation in CDM
Tiziano Schiavone, Enea Di Dio, Giuseppe Fanizza
Starting from a recently proposed framework for the evaluation of the cosmological averages, we evaluate the higher-order moments for the distribution of a given observable. Then,…
The Hawking Energy in a Perturbed Friedmann-Lemaître Universe
Dennis Stock, Enea Di Dio, Ruth Durrer
Hawking's quasi-local energy definition quantifies the energy enclosed by a spacelike 2-sphere in terms of the amount of lightbending on the sphere caused by the energy distributio…
Large Scale Limit of the Observed Galaxy Power Spectrum
Matteo Foglieni, Mattia Pantiri, Enea Di Dio +1
The large scale limit of the galaxy power spectrum provides a unique window into the early Universe through a possible detection of scale dependent bias produced by primordial non…
Wide-angle effects in the galaxy bispectrum
Kevin Pardede, Enea Di Dio, Emanuele Castorina
Primordial non-Gaussianities (PNG) leave unique signatures in the bispectrum of the large-scale structure. With upcoming galaxy surveys set to improve PNG constraints by at least o…
A smoking gun from the power spectrum dipole for elastic interactions in the dark sector
Jose Beltrán Jiménez, Enea Di Dio, David Figueruelo
Models with pure momentum exchange in the dark sector have been shown to provide a promising scenario to tackle the tension in the clustering inferred from high- and low-redshift p…
The gauge invariant cosmological Jacobi map from weak lensing at leading order
Giuseppe Fanizza, Enea Di Dio, Ruth Durrer +1
We compute the weak lensing Jacobi map at first order in perturbation theory and show that it is both, gauge invariant and symmetric. Linear perturbations therefore do not induce a…
The observed galaxy power spectrum in General Relativity
Emanuele Castorina, Enea di Dio
Measurements of the clustering of galaxies in Fourier space, and at low wavenumbers, offer a window into the early Universe via the possible presence of scale dependent bias genera…
Rotation of the CMB polarisation by foreground lensing
Enea Di Dio, Ruth Durrer, Giuseppe Fanizza +1
We investigate the weak lensing corrections to the CMB polarization anisotropies. We concentrate on the effect of rotation and show that the rotation of polarisation is a true phys…
Impact of next-to-leading order contributions to CMB lensing
Giovanni Marozzi, Giuseppe Fanizza, Enea Di Dio +1
In this Letter we study the impact on cosmological parameter estimation, from present and future surveys, due to lensing corrections on CMB temperature and polarization anisotropie…
CMB-lensing beyond the leading order: temperature and polarization anisotropies
Giovanni Marozzi, Giuseppe Fanizza, Enea Di Dio +1
We investigate the weak lensing corrections to the CMB temperature and polarization anisotropies. We consider all the effects beyond the leading order: post-Born corrections, LSS c…
Non-Gaussianities due to Relativistic Corrections to the Observed Galaxy Bispectrum
E. Di Dio, H. Perrier, R. Durrer +4
High-precision constraints on primordial non-Gaussianity (PNG) will significantly improve our understanding of the physics of the early universe. Among all the subtleties in using…
Lensing smoothing of BAO wiggles
Enea Di Dio
We study non-perturbatively the effect of the deflection angle on the BAO wiggles of the matter power spectrum in real space. We show that from redshift z~2 this introduces a dispe…
The Alcock Paczynski test with Baryon Acoustic Oscillations: systematic effects for future surveys
Francesca Lepori, Enea Di Dio, Matteo Viel +2
We investigate the Alcock Paczynski (AP) test applied to the Baryon Acoustic Oscillation (BAO) feature in the galaxy correlation function. By using a general formalism that include…
CMB-lensing beyond the Born approximation
Giovanni Marozzi, Giuseppe Fanizza, Enea Di Dio +1
We investigate the weak lensing corrections to the cosmic microwave background temperature anisotropies considering effects beyond the Born approximation. To this aim, we use the s…
The bispectrum of relativistic galaxy number counts
Enea Di Dio, Ruth Durrer, Giovanni Marozzi +1
We discuss the dominant terms of the relativistic galaxy number counts to second order in cosmological perturbation theory on sub-Hubble scales and on intermediate to large redshif…
Relativistic effects in Lyman-alpha forest
Vid Iršič, Enea Di Dio, Matteo Viel
We present the calculation of the Lyman-alpha (Lyman-) transmitted flux fluctuations with full relativistic corrections to the first order. Even though several studies exist on…
Galaxy number counts to second order and their bispectrum
Enea Di Dio, Ruth Durrer, Giovanni Marozzi +1
We determine the number counts to second order in cosmological perturbation theory in the Poisson gauge and allowing for anisotropic stress. The calculation is performed using an i…
Distance-redshift relation in plane symmetric universes
Julian Adamek, Enea Di Dio, Ruth Durrer +1
Distance measurements are usually thought to probe the background metric of the universe, but in reality the presence of perturbations will lead to deviations from the result expec…
Cosmological Parameter Estimation with Large Scale Structure Observations
Enea Di Dio, Francesco Montanari, Ruth Durrer +1
We estimate the sensitivity of future galaxy surveys to cosmological parameters, using the redshift dependent angular power spectra of galaxy number counts, , calc…
The CLASSgal code for Relativistic Cosmological Large Scale Structure
Enea Di Dio, Francesco Montanari, Julien Lesgourgues +1
We present some accurate and efficient computations of large scale structure observables, obtained with a modified version of the CLASS code which is made publicly available. This…
A longitudinal gauge degree of freedom and the Pais Uhlenbeck field
Jose Beltrán Jiménez, Enea Di Dio, Ruth Durrer
We show that a longitudinal gauge degree of freedom for a vector field is equivalent to a Pais-Uhlenbeck scalar field. With the help of this equivalence, we can determine natural i…
Vector and Tensor Contributions to the Luminosity Distance
Enea Di Dio, Ruth Durrer
We compute the vector and tensor contributions to the luminosity distance fluctuations in first order perturbation theory and we expand them in spherical harmonics. This work prese…
Back Reaction from Walls
Enea Di Dio, Marc Vonlanthen, Ruth Durrer
We study the distance-redshift relation in a universe filled with 'walls' of pressure-less dust separated by under dense regions. We show that as long as the density contrast of th…
