Supernovae type Ia data favour coupled phantom energy
Elisabetta Majerotto, Domenico Sapone, Luca Amendola
We estimate the constraints that the recent high-redshift sample of supernovae type Ia put on a phenomenological interaction between dark energy and dark matter. The interaction ca…
Perturbations growth and bias during acceleration
Luca Amendola, Domenico Tocchini-Valentini
In most models of dark energy the structure formation stops when the accelerated expansion begins. In contrast, we show that the coupling of dark energy to dark matter may induce t…
Likelihood analysis of the CfA2+SSRS2 and of the Las Campanas redshift surveys
E. Palladino, L. Amendola
We present the results from the correlation analysis of two galactic redshift surveys, the extended CfA2+SSRS2 and the slice centered on of Las Campanas. Furthermor…
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…
Non-Gaussian Chi-squared method with the multivariate Edgeworth expansion
Luca Amendola
I present here a generalization of the maximum likelihood method and the method to the cases in which the data are {\it not} assumed to be Gaussian distributed. The method, b…
Power spectrum for fractal distributions
F. Sylos Labini, L. Amendola
We study the behaviour of the power spectrum (PS) in the case of fractal structures. We show that in this case the main observational features of the PS, the large scale flattening…
