Cosmographic analysis with Chebyshev polynomials

Salvatore Capozziello, Rocco D'Agostino, Orlando Luongo

The limits of standard cosmography are here revised addressing the problem of error propagation during statistical analyses. To do so, we propose the use of Chebyshev polynomials t…

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…

The and tensions and the scale invariant spectrum

Micol Benetti, Leila L. Graef, Jailson S. Alcaniz

In a previous communication we showed that a joint analysis of Cosmic Microwave Background (CMB) data and the current measurement of the local expansion rate favours a model with a…

Clustering of Galaxies with f(R) gravity

Salvatore Capozziello, Mir Faizal, Mir Hameeda +3

Based on thermodynamics, we discuss the galactic clustering of expanding Universe by assuming the gravitational interaction through the modified Newton's potential given by …

Euclid: Superluminous supernovae in the Deep Survey

C. Inserra, R. C. Nichol, D. Scovacricchi +31

In the last decade, astronomers have found a new type of supernova called `superluminous supernovae' (SLSNe) due to their high peak luminosity and long light-curves. These hydrogen…

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…

Constraining quantum collapse inflationary models with current data: The semiclassical approach

María Pía Piccirilli, Gabriel León, Susana J. Landau +2

The hypothesis of the self-induced collapse of the inflaton wave function was introduced as a candidate for the physical process responsible for the emergence of inhomogeneity and…

Photometric redshifts for the Kilo-Degree Survey. Machine-learning analysis with artificial neural networks

M. Bilicki, H. Hoekstra, M. J. I. Brown +24

We present a machine-learning photometric redshift analysis of the Kilo-Degree Survey Data Release 3, using two neural-network based techniques: ANNz2 and MLPQNA. Despite limited c…

Directional dark matter detection sensitivity of a two-phase liquid argon detector

M. Cadeddu, M. Lissia, P. Agnes +38

We examine the sensitivity of a large scale two-phase liquid argon detector to the directionality of the dark matter signal. This study was performed under the assumption that, abo…

PSZ2LenS. Weak lensing analysis of the Planck clusters in the CFHTLenS and in the RCSLenS

Mauro Sereno, Giovanni Covone, Luca Izzo +3

The possibly unbiased selection process in surveys of the Sunyaev Zel'dovich effect can unveil new populations of galaxy clusters. We performed a weak lensing analysis of the PSZ2L…

Constraining f(T) teleparallel gravity by Big Bang Nucleosynthesis

S. Capozziello, G. Lambiase, E. N. Saridakis

We use BBN observational data on primordial abundance of to constrain f(T) gravity. The three most studied viable models, namely the power law, the exponential and…

Breaking the Vainshtein screening in clusters of galaxies

Vincenzo Salzano, David F. Mota, Salvatore Capozziello +1

In this work we will test an alternative model of gravity belonging to the large family of galileon models. It is characterized by an intrinsic breaking of the Vainshtein mechanism…
