Geometry of static perfect fluid spheres in general relativity
Behnaz Fazlpour, Ali Banijamali, Valerio Faraoni
We discuss the physical features of two recent classes of analytical solutions of the Einstein equations sourced by an exotic perfect fluid with equation of state . These…
Wyman's "other" scalar field solution, Sultana's generalization, and their Brans-Dicke and relatives
Ali Banijamali, Behnaz Fazlpour, Valerio Faraoni
Wyman's less known static and spherically symmetric solution of the Einstein-Klein-Gordon equations and its recent generalization for positive cosmological constant are discussed,…
Constraints on a scalar-tensor model with Gauss-Bonnet coupling from SN Ia and BAO observations
S. Bellucci, A. Banijamali, B. Fazlpour +1
In the present work, the observational consequences of a subclass of of the Horndeski theory have been investigated. In this theory a scalar field (tachyon field) non-minimally cou…
Observational constraints on tachyonic chameleon dark energy model
A. Banijamali, S. Bellucci, B. Fazlpour +1
It has been recently shown that tachyonic chameleon model of dark energy in which tachyon scalar field non-minimally coupled to the matter admits stable scaling attractor solution…
Non-minimally Coupled Tachyon Field in Teleparallel Gravity
Behnaz Fazlpour, Ali Banijamali
We perform a full investigation on dynamics of a new dark energy model in which the four-derivative of a non-canonical scalar field (tachyon) is non-minimally coupled to the vector…
Dynamics of Generalized Tachyon Field in Teleparallel Gravity
Behnaz Fazlpour, Ali Banijamali
We study dynamics of generalized tachyon scalar field in the framework of teleparallel gravity. This model is an extension of tachyonic teleparallel dark energy model which has bee…
