Closed and open FRW cosmologies with matter creation: Kinematic tests
J. S. Alcaniz, J. A. S. Lima
The limits imposed by the classical cosmological tests on closed and open FRW universes driven by adiabatic matter creation are investigated. Exact expressions for the lookback tim…

Minimal Angular Size of Distant Sources in Open, CDM, and Scalar Field Cosmologies
J. A. S. Lima, J. S. Alcaniz
We propose a simple method for determining the redshift at which the angular size of an extragalactic source with fixed proper diameter takes its minimal value. A closed an…

Flat FRW Cosmologies with Adiabatic Matter Creation: Kinematic tests
J. A. S. Lima, J. S. Alcaniz
Some observational consequences of a cosmological scenario driven by adiabatic matter creation are investigated. Exact expressions for the lookback time, age of the universe, lumin…
