Mass-concentration relation of clusters of galaxies from CFHTLenS

Wei Du, Zuhui Fan, Huanyuan Shan +4

Based on weak lensing data from the Canada-France-Hawaii Telescope Lensing Survey (CFHTLenS), in this paper we study the mass-concentration (-) relation for redMaP…

Bounds on very low reheating scenarios after Planck

P. F. de Salas, M. Lattanzi, G. Mangano +3

We consider the case of very low reheating scenarios () with a better calculation of the production of the relic neutrino background (with thr…

Results from the first use of low radioactivity argon in a dark matter search

The DarkSide Collaboration, P. Agnes, L. Agostino +158

Liquid argon is a bright scintillator with potent particle identification properties, making it an attractive target for direct-detection dark matter searches. The DarkSide-50 dark…

Updated F(T) gravity constraints from high redshift cosmography

Ester Piedipalumbo, Enrica Della Moglie, Roberto Cianci

In the last dozen years a wide and variegated mass of observational data revealed that the universe is now expanding at an accelerated rate. In the absence of a well-based theory t…

Cosmological parameters from lenses distance ratio

Vincenzo F. Cardone, Ester Piedipalumbo, Paolo Scudellaro

Strong lensing provides popular techniques to investigate the mass distribution of intermediate redshift galaxies, testing galaxy evolution and formation scenarios. It especially p…

Cosmological constraints on the neutron lifetime

Laura Salvati, Luca Pagano, Rosa Consiglio +1

We derive new constraints on the neutron lifetime based on the recent Planck 2015 observations of temperature and polarization anisotropies of the CMB. Under the assumption of stan…

Cosmological evolution of thermal relic particles in gravity

S. Capozziello, V. Galluzzi, G. Lambiase +1

By considering gravity models, the cosmic evolution is modified with respect to the standard CDM scenario. In particular, the thermal history of particles results modifie…

Primordial Non-Gaussianities of inflationary step-like models

Camila P. Novaes, Micol Benetti, Armando Bernui

We use Minkowski Functionals to explore the presence of non-Gaussian signatures in simulated cosmic microwave background (CMB) maps. Precisely, we analyse the non-Gaussianities pro…
