Current lookback time-redshift bounds on dark energy
M. A. Dantas, J. S. Alcaniz, N. Pires
We investigate observational constraints on dark energy models from lookback time (LT) estimates of 32 old passive galaxies distributed over the redshift interval $0.11 \leq z \leq…

Lookback time bounds from energy conditions
J. Santos, J. S. Alcaniz, M. J. Reboucas +1
In general relativity, the energy conditions are invoked to restrict general energy-momentum tensors on physical grounds. We show that in the standard Friedmann-Lemaitre-Robertson-…
