Gravitational Waves and Scalar Perturbations from Spectator Fields
Matteo Biagetti, Emanuela Dimastrogiovanni, Matteo Fasiello +1
The most conventional mechanism for gravitational waves (gw) production during inflation is the amplification of vacuum metric fluctuations. In this case the gw production can be u…
On the halo velocity bias
Matteo Biagetti, Vincent Desjacques, Alex Kehagias +1
It has been recently shown that any halo velocity bias present in the initial conditions does not decay to unity, in agreement with predictions from peak theory. However, this is a…
Ultraviolet background fluctuations with clustered sources
Vincent Desjacques, Azadeh Moradinezhad Dizgah, Matteo Biagetti
We develop a count-in-cells approach to the distribution of ultraviolet background fluctuations that includes source clustering. We demonstrate that an exact expression can be obta…
Non-local halo bias with and without massive neutrinos
Matteo Biagetti, Vincent Desjacques, Alex Kehagias +1
Understanding the biasing between the clustering properties of halos and the underlying dark matter distribution is important for extracting cosmological information from ongoing a…
