Chaplygin gas of Tachyon Nature Imposed by Noether Symmetry and constrained via H(z)data
《Research in Astronomy and Astrophysics》2016年第4期113-120,共8页Lucas Gardai Collodel Gilberto Medeiros Kremer 
CNPq for the financial support that allowed this work to be done
An action of general form is proposed for a Universe containing matter, radiation and dark energy. The latter is interpreted as a tachyon field non-minimally coupled to the scalar curvature. The Palatini approach is u...

supported by EU funds in the frame of the program FP7-Marie Curie Initial Training Network INDEX NO. 289968
We consider a tachyonic scalar field as a model of dark energy with interac- tion between components in the case of variable G and A. We assume a fiat Universe with a specific form of scale factor and study cosmologic...
