Gravitational wave detection by bounded cold electronic plasma in a long pipe
O. Jalili, S. Rouhani, M. V. Takook
We intend to propose an experimental sketch to detect gravitational waves (GW) directly, using an cold electronic plasma in a long pipe. By considering an cold electronic plasma in…
Weyl-invariant extension of the Metric-Affine Gravity
R. Vazirian, M. R. Tanhayi, Z. A. Motahar
Metric-affine geometry provides a non-trivial extension of the general relativity where the metric and connection are treated as the two independent fundamental quantities in const…
Signature transition in Einstein-Cartan cosmology
Babak Vakili, Shahram Jalalzadeh
In the context of Einstein-Cartan theory of gravity, we consider a Friedmann-Lemaitre-Robertson-Walker (FLRW) cosmological model with Weyssenhoff perfect fluid. We focus attention…
Asymptotically Lifshitz black hole solutions in F(R) gravity
S. H. Hendi, B. Eslam Panah, C. Corda
We consider a class of spherically symmetric spacetime to obtain some interesting solutions in F(R) gravity without matter field (pure gravity). We investigate the geometry of the…
Gravitational lensing of STU black holes
Hassan Saadat
In this paper we study gravitational lensing by STU black holes. We considered extremal limit of two special cases of zero-charged and one-charged black holes, and obtain the defle…
Effect of Varying Bulk Viscosity on Generalized Chaplygin Gas
H. Saadat, B. Pourhassan
In this paper, viscous generalized Chaplygin gas as a model of dark energy considered. We assume non-constant bulk viscous coefficient and study dark energy density. We consider se…
