Non-local dilaton coupling to dark matter: cosmic acceleration and pressure backreaction
L. Amendola, M. Gasperini, C. Ungarelli
A model of non-local dilaton interactions, motivated by string duality symmetries, is applied to a scenario of "coupled quintessence" in which the dilaton dark energy is non-locall…
Constraining the growth factor with baryon oscillations
Domenico Sapone, Luca Amendola
The growth factor of linear fluctuations is probably one of the least known quantity in observational cosmology. Here we discuss the constraints that baryon oscillations in galaxy…
Peculiar acceleration
Luca Amendola, Claudia Quercellini, Amedeo Balbi
It has been proposed recently to observe the change in cosmological redshift of distant galaxies or quasars with the next generation of large telescope and ultra-stable spectrograp…
Observational constraints on the linear fluctuation growth rate
Cinzia Di Porto, Luca Amendola
Several experiments in the near future will test dark energy through its effects on the linear growth of matter perturbations. It is therefore important to find simple and at the s…
Growing Matter
Luca Amendola, Marco Baldi, Christof Wetterich
We investigate quintessence cosmologies with a matter component consisting of particles with an increasing mass. While negligible in early cosmology, the appearance of a growing ma…
