Coupled Quintessence
Luca Amendola
A new component of the cosmic medium, a light scalar field or ''quintessence '', has been proposed recently to explain cosmic acceleration with a dynamical cosmological constant. S…
Time variability of the gravitational constant and Type Ia supernovae
Luca Amendola, Stefano Corasaniti, Franco Occhionero
We investigate to which extent a time variation of the gravitational constant or other fundamental constants affects the best fit of the Hubble diagram of type Ia supernovae. In pa…
Perturbations in a coupled scalar field cosmology
Luca Amendola
I analyze the density perturbations in a cosmological model with a scalar field coupled to ordinary matter, such as one obtains in string theory and in conformally transformed scal…
Scaling solutions in general non-minimal coupling theories
Luca Amendola
A class of generalized non-minimal coupling theories is investigated, in search of scaling attractors able to provide an accelerated expansion at the present time. Solutions are fo…
The scale of homogeneity in the Las Campanas Redshift Survey
Luca Amendola, Emilia Palladino
We analyse the Las Campanas Redshift Survey using the integrated conditional density (or density of neighbors) in volume-limited subsamples up to unprecedented scales (200 Mpc/)…
