Constraints on Extended Quintessence from High - Redshift Supernovae
We obtain constraints on quintessence models from magnitude-redshift measurements of 172 type Ia Supernovae. The considered quintessence models are ordinary quintessence, with Ratra-Peebles and SUGRA potentials, and extended quintessence with a Ratra-Peebles potential. We compute confidence regions in the Ωm0 −α plane and find that for SUGRA potentials it is not possible to obtain useful constr...
متن کاملSupernovae Ia , Evolution and Quintessence ∗
Quintessence models with a dark energy generated by pseudo Nambu– Goldstone bosons provide a natural framework in which to test the possibility that type Ia supernovae luminosity distance measurements are at least partially due to an evolution of the sources, since these models can have parameter values for which the expansion of the Universe is decelerating as well as values for which it is ac...
متن کاملRadiative constraints on brane quintessence
We investigate the constraints on quintessence arising from both renormalisable and non-renormalisable couplings where the 5d Planck mass is around the TeV scale. The quintessence field vacuum expectation value is typically of order the 4d Planck mass, while non-renormalisable operators are expected to be suppressed by the 5d Planck mass. Non-renormalisable operators are therefore important in ...
متن کاملProbing quintessence: reconstruction and parameter estimation from supernovae
We explore the prospects for using future supernova observations to probe the dark energy. We focus on quintessence, an evolving scalar field that has been suggested as a candidate for the dark energy. After simulating the observations that would be expected from the proposed SuperNova / Acceleration Probe satellite (SNAP), we investigate two methods for extracting information about quintessenc...
متن کاملConstraints on a quintessence model from gravitational lensing statistics
Constraints on an exact quintessence scalar-field model with an exponential potential are derived from gravitational lens statistics. An exponential potential can account for data from both optical quasar surveys and radio selected sources. Based on the Cosmic Lens All-Sky Survey (CLASS) sample, lensing statistics provides, for the pressureless matter density parameter, an estimate of ΩM0 = 0.3...
