PArthENoPE reloaded
R. Consiglio, P. F. de Salas, G. Mangano +3
We describe the main features of a new and updated version of the program PArthENoPE, which computes the abundances of light elements produced during Big Bang Nucleosynthesis. As t…
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…
A gravitational-wave standard siren measurement of the Hubble constant
B. P. Abbott, R. Abbott, T. D. Abbott +1308
The detection of GW170817 in both gravitational waves and electromagnetic waves heralds the age of gravitational-wave multi-messenger astronomy. On 17 August 2017 the Advanced LIGO…
Phantom Dirac-Born-Infeld Dark Energy
Gabriela Barenboim, William H. Kinney, Michael J. P. Morse
Motivated by the apparent discrepancy between Cosmic Microwave Background measurements of the Hubble constant and measurements from Type-Ia supernovae, we construct a model for Dar…
Warm Dark Matter and Cosmic Reionization
Pablo Villanueva-Domingo, Nickolay Y. Gnedin, Olga Mena
In models with dark matter made of particles with keV masses, such as a sterile neutrino, small-scale density perturbations are suppressed, delaying the period at which the lowest…
Primordial Black Holes and Slow-Roll Violation
Hayato Motohashi, Wayne Hu
For primordial black holes (PBH) to be the dark matter in single-field inflation, the slow-roll approximation must be violated by at least in order to enhance the cur…
Can interacting dark energy solve the tension?
Eleonora Di Valentino, Alessandro Melchiorri, Olga Mena
The answer is Yes! We indeed find that interacting dark energy can alleviate the current tension on the value of the Hubble constant between the Cosmic Microwave Background a…
constant-roll inflation
Hayato Motohashi, Alexei A. Starobinsky
The previously introduced class of two-parametric phenomenological inflationary models in General Relativity in which the slow-roll assumption is replaced by the more general, cons…
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…
Constant-roll inflation: confrontation with recent observational data
Hayato Motohashi, Alexei A. Starobinsky
The previously proposed class of phenomenological inflationary models in which the assumption of inflaton slow-roll is replaced by the more general, constant-roll condition is comp…
The best fit for the observed galaxy Counts-in-Cell distribution function
Ll. Hurtado-Gil, V. J. Martínez, P. Arnalte-Mur +3
The Sloan Digital Sky Survey (SDSS) is the first dense redshift survey encompassing a volume large enough to find the best analytic probability density function that fits the galax…
Warm dark matter and the ionization history of the Universe
Laura Lopez-Honorez, Olga Mena, Sergio Palomares-Ruiz +1
In warm dark matter scenarios structure formation is suppressed on small scales with respect to the cold dark matter case, reducing the number of low-mass halos and the fraction of…
The history of chemical enrichment in the intracluster medium from cosmological simulations
V. Biffi, S. Planelles, S. Borgani +8
The distribution of metals in the intracluster medium (ICM) of galaxy clusters provides valuable information on their formation and evolution, on the connection with the cosmic sta…
Real- and redshift-space halo clustering in cosmologies
Pablo Arnalte-Mur, Wojciech A. Hellwing, Peder Norberg
We present two-point correlation function statistics of the mass and the halos in the chameleon modified gravity scenario using a series of large volume N-body simulations.…
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-…
Unveiling secrets with cosmological data: neutrino masses and mass hierarchy
Sunny Vagnozzi, Elena Giusarma, Olga Mena +4
Using some of the latest cosmological datasets publicly available, we derive the strongest bounds in the literature on the sum of the three active neutrino masses, , within th…
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…
