Hunting Dark Matter with the Einstein Telescope
A. J. Iovino, M. Maggiore, N. Muttoni +1
Too light primordial black holes evaporate and are therefore strongly constrained by various bounds, e.g. Cosmic Microwave Background distortion. However, if they are formed strong…
Dark Matter from Eternity
G. Franciolini, M. Peloso, A. Riotto
We propose that the totality of dark matter in the universe might ascribe its origin to one of the key properties of cosmological inflation, that it may be eternal: regions that at…
Are Primordial Black Holes Truly Fine-Tuned?
A. J. Iovino, A. Riotto
Single-field inflationary models which generate primordial black holes through the enhancement of the curvature primordial power at small scales are commonly criticized and frequen…
The Irrelevance of Primordial Black Hole Clustering in the LVK mass range
F. Crescimbeni, V. Desjacques, G. Franciolini +6
We show that in realistic models where primordial black holes are formed due to the collapse of sizeable inflationary perturbations, their initial spatial clustering beyond Poisson…
How Well Do We Know the Scalar-Induced Gravitational Waves?
A. J. Iovino, S. Matarrese, G. Perna +2
Gravitational waves sourced by amplified scalar perturbations are a common prediction across a wide range of cosmological models. These scalar curvature fluctuations are inherently…
A Consistency Relation for the Observed Galaxy Bispectrum and the Local non-Gaussianity from Relativistic Corrections
A. Kehagias, A. Moradinezhad Dizgah, J. Noreña +2
We obtain a consistency relation for the observed three-point correlator of galaxies. It includes relativistic effects and it is valid in the squeezed limit. Furthermore, the consi…
A Consistency Relation for the CMB B-mode Polarization in the Squeezed Limit
A. Kehagias, A. Moradinezhad-Dizgah, J. Noreña +2
A large-scale temperature perturbation has a non-zero correlation with the power spectrum of B-modes of cosmological origin on short scales while the corresponding correlation is e…
