Cárdenas, V.2023-03-162023-03-162006-05Physical Review D - Particles, Fields, Gravitation and Cosmology, Volume 73, Issue 102006, Article number 1035121550-2368https://repositorio.unab.cl/xmlui/handle/ria/47526Indexación: Scopus.I study the possibility of constructing an observationally viable scenario where both early inflation and the recently detected accelerated expansion of the universe can be explained by using a single scalar field associated with the tachyon. The reheating phase becomes crucial in enabling us to have a consistent cosmology and also to get a second accelerated expansion period. A discussion using an exponential potential is presented.enCosmosChaplygin GasCosmological ModelsArtículoAttribution 4.0 International (CC BY 4.0)10.1103/PhysRevD.73.103512
