Constraint of Void Bias on Primordial non-Gaussianity
Kwan Chuen Chan, Nico Hamaus, Matteo Biagetti
We study the large-scale bias parameter of cosmic voids with primordial non-Gaussian (PNG) initial conditions of the local type. In this scenario, the dark matter halo bias exhibit…
Abundance of peaks and dips in three-dimensional mass and halo density fields: a test for cosmology
Adi Nusser, Matteo Biagetti, Vincent Desjacques
Using cosmological N-body simulations, we study the abundance of local maxima (peaks) and minima (dips) identified in the smoothed distribution of halos and dark matter (DM) on sca…
Primordial Black Holes from Inflation and Quantum Diffusion
Matteo Biagetti, Gabriele Franciolini, Alex Kehagias +1
Primordial black holes as dark matter may be generated in single-field models of inflation thanks to the enhancement at small scales of the comoving curvature perturbation. This me…
