Cosmological model with generalized Chaplygin gas and recent astronomical observations
For gravitational models describing accelerated expansion of the Universe we consider limitations on their parameters coming from recent observational data for type Ia supernovae, baryon acoustic oscillations, and from measuring the Hubble parameter H(z) depending on redshift. The calculated limitations are applied to the most popular \LambdaCDM model with the \Lambda term (dark energy) and cold dark matter and to the model with generalized modified Chaplygin gas. Prediction of these models appeared to be very close.
