Testing Dark Energy models vs CDM Cosmology by Supernovae and Gamma Ray Bursts
L. Izzo, S. Capozziello, G. Covone +1
A new method to constrain the cosmological equation of state is proposed by using combined samples of gamma-ray bursts (GRBs) and supernovae (SNeIa). The Chevallier-Polarski-Linder…

Stochastic background of gravitational waves "tuned" by gravity
M. De Laurentis, S. Capozziello, L. Izzo
The cosmological background of gravitational waves can be tuned by Extended Theories of Gravity. In particular, it can be shown that assuming a generic function of the Ricci…

Detecting the Cosmological Stochastic Background of Gravitational Waves with FastICA
L. Izzo, S. Capozziello, M. De Laurentis
We show that the stochastic background of gravitational waves, produced in the early cosmological epochs, strictly depends on the assumed theory of gravity. In particular, the spec…
