Cosmological models in scalar tensor theories of gravity and observations: a class of general solutions
M. Demianski, E. Piedipalumbo, C. Rubano +1
We consider cosmological models in scalar tensor theories of gravity that describe an accelerating universe, and we study a family of inverse power law potentials, for which exact…
Constraining scalar-tensor quintessence by cosmic clocks
S. Capozziello, P. K. S. Dunsby, E. Piedipalumbo +1
Scalar-tensor quintessence models can be constrained by identifying suitable cosmic clocks which allow to select confidence regions for cosmological parameters. In particular, we c…
Dynamical and gravitational lensing properties of a new phenomenological model of elliptical galaxies
C. Tortora, V. F. Cardone, E. Piedipalumbo
Recent observations of the line of sight velocity profile of elliptical galaxies have furnished controversial results with some works favouring the presence of a large amount of da…
Accelerating universe in scalar tensor models - confrontation of theoretical predictions with observations
M. Demianski, E. Piedipalumbo, C. Rubano +1
We consider scalar tensor theories of gravity assuming that the scalar field is non minimally coupled with gravity. We use this theory to study evolution of a flat homogeneous and…
Dark energy exponential potential models as curvature quintessence
S. Capozziello, V. F. Cardone, E. Piedipalumbo +1
It has been recently shown that, under some general conditions, it is always possible to find a fourth order gravity theory capable of reproducing the same dynamics of a given dark…
Spherical galaxy models with power law logarithmic slope
V. F. Cardone, E. Piedipalumbo, C. Tortora
We present a new family of spherically symmetric models for the luminous components of elliptical and spiral galaxies and their dark matter haloes. Our starting point is a general…
