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…
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…
Two viable quintessence models of the Universe: confrontation of theoretical predictions with observational data
M. Demianski, E. Piedipalumbo, C. Rubano +1
We use some of the recently released observational data to test the viability of two classes of minimally coupled scalar field models of quintessence with exponential potentials fo…
