Gauge-invariant analysis of perturbations in Chaplygin gas unified models of dark matter and dark energy
V. Gorini, A. Y. Kamenshchik, U. Moschella +2
We exploit the gauge-invariant formalism to analyse the perturbative behaviour of two cosmological models based on the generalized Chaplygin gas describing both dark matter and dar…

Conservation laws and scattering for de Sitter classical particles
S. Cacciatori, V. Gorini, A. Kamenshchik +1
Starting from an intrinsic geometric characterization of de Sitter timelike and lightlike geodesics we give a new description of the conserved quantities associated with classical…
