Journal ArticleDOI
Non-Gaussian formation of primordial black holes: effects on the threshold
TL;DR: In this paper, the authors investigated the impact of non-Gaussianity on the critical threshold, which measures the excess of mass of the perturbation, finding a relative change with respect to the value obtained using a linear relation between curvature perturbations and overdensity.
Journal ArticleDOI
Anisotropic Bispectrum of Curvature Perturbations from Primordial Non-Abelian Vector Fields
TL;DR: In this paper, the authors consider a primordial SU(2) vector multiplet during inflation in models where quantum fluctuations of vector fields are involved in producing the curvature perturbation.
Journal ArticleDOI

TL;DR: In this article, the LHC Dark Matter Working Group discussed how to present LHC results on s-channel simplified dark matter models and compare them to direct (indirect) detection experiments.
Journal ArticleDOI
Characterizing the cosmological gravitational wave background: Anisotropies and non-Gaussianity
Nicola Bartolo,Nicola Bartolo,Daniele Bertacca,Sabino Matarrese,Marco Peloso,Angelo Ricciardone,Antonio Riotto,Gianmassimo Tasinato +7 more
TL;DR: In this paper, the effects of large-scale scalar and tensor linearized perturbations on the SGWB energy density were investigated. And the results showed that the effect of large scale scalar perturbation typically leads to anisotropies with order one dependence on frequency, which can offer new tools to discriminate different sources of GWs.
Journal ArticleDOI
Non-Gaussianity in the Cosmic Microwave Background Anisotropies at Recombination in the Squeezed limit
TL;DR: In this paper, the second-order cosmic microwave background temperature anisotropies at the recombination epoch in the squeezed limit were estimated and the contamination of the primordial local non-Gaussianity was deduced.
