CDM Accelerating Cosmology as an Alternative to LCDM model
TL;DR: In this article, a new accelerating cosmology driven only by baryons plus cold dark matter (CDM) is proposed in the framework of general relativity, where the present accelerating stage of the Universe is powered by the negative pressure describing the gravitationally-induced particle production of cold-dark matter particles.

CDM accelerating cosmology as an alternative to ΛCDM model
TL;DR: In this paper, a new accelerating cosmology driven only by baryons plus cold dark matter (CDM) is proposed in the framework of general relativity, where the present accelerating stage of the Universe is powered by the negative pressure describing the gravitationally-induced particle production of cold- dark matter particles.
Journal ArticleDOI
Can dark matter decay in dark energy
S. H. Pereira,J. F. Jesus +1 more
TL;DR: In this paper, the authors analyze the interaction between dark energy and dark matter from a thermodynamic perspective and find that, for a fairly simple interaction, the dark matter decay is favored with a probability of ∼93% over the dark energy decay.
Journal ArticleDOI
Shear and rotation in Chaplygin cosmology
TL;DR: In this article, the effect of shear and rotation on the spherical collapse model in a general Chaplygin gas (gCg)-dominated universe was studied. And the authors showed that the joint effect of rotation and shear is that of slowing down the collapse with respect to the simple SCM.
Journal ArticleDOI
New coupled quintessence cosmology
TL;DR: In this article, the authors proposed a new cosmological scenario where radiation and baryons are conserved, while the dark energy component is decaying into cold dark matter, which is characterized by a positive parameter {epsilon}.
