High Redshift Investigation On The Dark Energy Equation of State

E. Piedipalumbo, E. Della Moglie, M. De Laurentis +1

The understanding of the accelerated expansion of the Universe poses one of the most fundamental questions in physics and cosmology today. Whether or not the acceleration is driven…

Detectability of Torsion Gravity via Galaxy Clustering and Cosmic Shear Measurements

Stefano Camera, Vincenzo F. Cardone, Ninfa Radicella

Alterations of the gravity Lagrangian introduced in modified torsion gravity theories---also referred to as gravity---allows for an accelerated expansion in a matter dominat…

Constraining f(R) gravity with PLANCK data on galaxy cluster profiles

I. De Martino, M. De Laurentis, F. Atrio-Barandela +1

Models of gravity that introduce corrections to the Newtonian potential in the weak field limit are tested at the scale of galaxy clusters. These models can explain the dyna…

The mass-concentration relation in massive galaxy clusters at redshift ~1

Mauro Sereno, Giovanni Covone

Mass and concentration of clusters of galaxies are related and evolving with redshift. We study the properties of a sample of 31 massive galaxy clusters at high redshift, 0.8 < z <…

The strongest bounds on active-sterile neutrino mixing after Planck data

Alessandro Mirizzi, Gianpiero Mangano, Ninetta Saviano +4

Light sterile neutrinos can be excited by oscillations with active neutrinos in the early universe. Their properties can be constrained by their contribution as extra-radiation, pa…

Multi-momentum and multi-flavour active-sterile neutrino oscillations in the early universe: role of neutrino asymmetries and effects on nucleosynthesis

Ninetta Saviano, Alessandro Mirizzi, Ofelia Pisanti +3

We perform a study of the flavour evolution in the early universe of a multi-flavour active-sterile neutrino system with parameters inspired by the short-baseline neutrino anomalie…

Flux and color variations of the doubly imaged quasar UM673

D. Ricci, A. Elyiv, F. Finet +42

With the aim of characterizing the flux and color variations of the multiple components of the gravitationally lensed quasar UM673 as a function of time, we have performed multi-ep…
