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…
