The Halo Bispectrum in N-body Simulations with non-Gaussian Initial Conditions
Emiliano Sefusatti, Martin Crocce, Vincent Desjacques
We present measurements of the bispectrum of dark matter halos in numerical simulations with non-Gaussian initial conditions of the local type. We show, in the first place, that th…
Extragalactic gamma-ray signal from Dark Matter annihilation: a power spectrum based computation
Pasquale D. Serpico, Emiliano Sefusatti, Michael Gustafsson +1
We revisit the computation of the extragalactic gamma-ray signal from cosmological dark matter annihilations. The prediction of this signal is notoriously model dependent, due to d…
The nonlinear power spectrum in clustering quintessence cosmologies
Guido D'Amico, Emiliano Sefusatti
We study the nonlinear evolution of density perturbations in cosmologies where the late-time accelerated expansion is driven by a quintessence field with vanishing speed of sound.…
Primordial Non-Gaussianity and the Statistics of Weak Lensing and other Projected Density Fields
Donghui Jeong, Fabian Schmidt, Emiliano Sefusatti
Estimators for weak lensing observables such as shear and convergence generally have non-linear corrections, which, in principle, make weak lensing power spectra sensitive to primo…
Cosmological structure formation with clustering quintessence
Emiliano Sefusatti, Filippo Vernizzi
We study large-scale structure formation in the presence of a quintessence component with zero speed of sound in the framework of Eulerian Perturbation Theory. Due to the absence o…
