On the Gauge Invariance of Cosmological Gravitational Waves
V. De Luca, G. Franciolini, A. Kehagias +1
The issue of the gauge invariance of gravitational waves arises if they are produced in the early universe at second-order in perturbation theory. We address it by dividing the dis…
Gravitational Waves from Peaks
V. De Luca, V. Desjacques, G. Franciolini +1
We discuss a novel mechanism to generate gravitational waves in the early universe. A standard way to produce primordial black holes is to enhance at small-scales the overdensity p…
The Ineludible non-Gaussianity of the Primordial Black Hole Abundance
V. De Luca, G. Franciolini, A. Kehagias +3
We study the formation of primordial black holes when they are generated by the collapse of large overdensities in the early universe. Since the density contrast is related to the…
The Initial Spin Probability Distribution of Primordial Black Holes
V. De Luca, V. Desjacques, G. Franciolini +2
We study the spin of primordial black holes produced by the collapse of large inhomogeneities in the early universe. Since such primordial black holes originate from peaks, that is…
