Deflationary cosmology: observational expressions
Full text linkWe discuss the classical cosmological tests for a large class of FRW type
models driven by a decaying vacuum energy density. Analytic expressions for the
lookback time, age of the universe, luminosity distance, angular diameter, and
galaxy number counts versus redshift are derived and their meaning discussed in
detail. It is found that the standard FRW results are significantly altered,
showing that such tests may constrain the physical parameters of these models
which are also in agreement to the accelerated expansion suggested by the
latest SNe type Ia observations.Comment: 8 pages, 8 figures, LaTe
