Precision distance‐redshift observations can map out the recent expansion history of the universe, including the present acceleration and the transition to matter dominated deceleration. The proposed Supernova/Acceleration Probe (SNAP) will carry out observations determining the components and equations of state of the energy density, providing insights into the cosmological model, the nature of the accelerating dark energy, and potentially clues to fundamental high energy physics theories and…

Testing the running of the cosmological constant with type Ia supernovae at high z
Within the quantum field theory context the idea of a `cosmological constant' (CC) evolving with time looks quite natural as it just reflects the change of the vacuum energy with the typical energy
Bayesian Analysis of the Chaplygin Gas and Cosmological Constant Models Using the SNe ia Data
The type Ia supernovae observational data are used to estimate the parameters of a cosmological model with cold dark matter and the Chaplygin gas. This exotic gas, which is characterized by a
