Was there an early reionization component in our universe?
Pablo Villanueva-Domingo, Stefano Gariazzo, Nickolay Y. Gnedin +1
A deep understanding of the Epoch of Reionization is still missing in our knowledge of the universe. While future probes will allow us to test the precise evolution of the free ele…
Neutrino clustering in the Milky Way
Stefano Gariazzo
The Cosmic Neutrino Background is a prediction of the standard cosmological model, but it has been never observed directly. In the experiments with the aim of detecting relic CNB n…
Calculation of the local density of relic neutrinos
P. F. de Salas, S. Gariazzo, J. Lesgourgues +1
Nonzero neutrino masses are required by the existence of flavour oscillations, with values of the order of at least 50 meV. We consider the gravitational clustering of relic neutri…
Cosmological searches for a non-cold dark matter component
Stefano Gariazzo, Miguel Escudero, Roberta Diamanti +1
We explore an extended cosmological scenario where the dark matter is an admixture of cold and additional non-cold species. The mass and temperature of the non-cold dark matter par…
Updated Global 3+1 Analysis of Short-BaseLine Neutrino Oscillations
S. Gariazzo, C. Giunti, M. Laveder +1
We present the results of an updated fit of short-baseline neutrino oscillation data in the framework of 3+1 active-sterile neutrino mixing. We first consider and d…
The running of featureful primordial power spectra
Stefano Gariazzo, Olga Mena, Victor Miralles +2
Current measurements of the temperature and polarization anisotropy power spectra of the Cosmic Microwave Background (CMB) seem to indicate that the naive expectation for the slow-…
Cold dark matter plus not-so-clumpy dark relics
Roberta Diamanti, Shin'ichiro Ando, Stefano Gariazzo +2
Various particle physics models suggest that, besides the (nearly) cold dark matter that accounts for current observations, additional but sub-dominant dark relics might exist. The…
