We obtain the different astrophysical objects derived from the presence of different horizons. Thermodynamics for this kind of black holes is studied for negative values of the curvature, revealing that we can distinguish between two kind of BH: fast and slow.engjournal articlehttp://dx.doi.org/10.1063/1.4734454http://aip.scitation.orghttp://arxiv.org/abs/1202.0853open access53Modified gravityDark-matterThermodynamicsBraneCosmologyDesitterSpace.Física-Modelos matemáticos
