Surface Density of dark matter haloes on galactic and cluster scales
A. Del Popolo, V. Cardone, G. Belvedere
In this paper, in the framework of the secondary infall model, the correlation between the central surface density and the halo core radius of galaxy, and cluster of galaxies, dark…
On the shear estimation bias induced by the spatial variation of colour across galaxy profiles
Elisabetta Semboloni, Henk Hoekstra, Zhuoyi Huang +13
The spatial variation of the colour of a galaxy may introduce a bias in the measurement of its shape if the PSF profile depends on wavelength. We study how this bias depends on the…
Newtonian acceleration scales in spiral galaxies
V. F. Cardone, A. Del Popolo
We revisit the issue of the constancy of the dark matter (DM) and baryonic Newtonian acceleration scales within the DM scale radius by considering a large sample of late - type gal…
Testing the distance duality relation with present and future data
Vincenzo F. Cardone, Susanna Spiro, Isobel Hook +1
The assumptions that "light propagates along null geodesics of the spacetime metric" and "the number of photons is conserved along the light path" lead to the distance duality rela…
Constraining massive gravity with recent cosmological data
Vincenzo F. Cardone, Ninfa Radicella, Luca Parisi
A covariant formulation of a theory with a massive graviton and no negative energy state has been recently proposed as an alternative to the usual General Relativity framework. For…
Accelerating f(T) gravity models constrained by recent cosmological data
Vincenzo F. Cardone, Ninfa Radicella, Stefano Camera
Generalised Teleparallel gravity, also referred to as f(T) gravity, has been recently proposed as an extended theory of gravitation able to give rise to an accelerated expansion in…
