Latest supernovae constraints on f(R) cosmologies
J. Santos, J. S. Alcaniz, F. C. Carvalho +1
A class of modified gravity, known as -gravity, has presently been applied to Cosmology as a realistic alternative to dark energy. In this paper we use the most recent Type-I…

Hybrid dark energy
J. S. Alcaniz, R. Silva, F. C. Carvalho +1
Extending previous results [Phys. Rev. Lett. 97, 081301 (2006)], we explore the cosmological implications of a new quintessence scenario driven by a slow rolling homogeneous scalar…

Cosmological Constraints from Hubble Parameter on f(R) Cosmologies
F. C. Carvalho, E. M. Santos, J. S. Alcaniz +1
Modified gravity in the Palatini approach has been presently applied to Cosmology as a realistic alternative to dark energy. In this concern, a number of authors have search…
