Phantom damping of matter perturbations
Luca Amendola, Shinji Tsujikawa, M. Sami
Cosmological scaling solutions are particularly important in solving the coincidence problem of dark energy. We derive the equations of sub-Hubble linear matter perturbations for a…

Observational constraints on braneworld inflation: the effect of a Gauss-Bonnet term
Shinji Tsujikawa, M. Sami, Roy Maartens
High-energy modifications to general relativity introduce changes to the perturbations generated during inflation, and the latest high-precision cosmological data can be used to pl…
