The Covariance of Squeezed Bispectrum Configurations
Matteo Biagetti, Lina Castiblanco, Jorge Noreña +1
We measure the halo bispectrum covariance in a large set of N-body simulations and compare it with theoretical expectations. We find a large correlation among (even mildly) squeeze…
The reach of next-to-leading-order perturbation theory for the matter bispectrum
Davit Alkhanishvili, Cristiano Porciani, Emiliano Sefusatti +4
We provide a comparison between the matter bispectrum derived with different flavours of perturbation theory at next-to-leading order and measurements from an unprecedentedly large…
The Formation Probability of Primordial Black Holes
Matteo Biagetti, Valerio De Luca, Gabriele Franciolini +2
We calculate the exact formation probability of primordial black holes generated during the collapse at horizon re-entry of large fluctuations produced during inflation, such as th…
