ZKDR Distance, Angular Size and Phantom Cosmology
R. C. Santos, J. A. S. Lima
The influence of mass inhomogeneities on the angular size-redshift test is investigated for a large class of flat cosmological models driven by dark energy plus a cold dark matter…

An old quasar in a young dark energy-dominated universe?
A. Friaca, J. S. Alcaniz, J. A. S. Lima
Dark energy is the invisible fuel that seems to drive the current acceleration of the Universe. Its presence, which is inferred from an impressive convergence of high-quality obser…

Dark energy and the angular size - redshift diagram for milliarcsecond radio sources
J. A. S. Lima, J. S. Alcaniz
We investigate observational constraints on the cosmic equation of state from measurements of angular size for a large sample of milliarcsecond compact radio sources. The results a…
