Exact solution of vacuum field equation in Finsler spacetime
X Li, Z Chang - Physical Review D, 2014 - APS
We suggest that the vacuum field equation in Finsler spacetime is equivalent to the
vanishing of the Ricci scalar. The Schwarzschild metric can be deduced from a solution of …

Constraining anisotropic models of the early Universe with WMAP9 data
SR Ramazanov, GI Rubtsov - Physical Review D, 2014 - APS
We constrain several models of the early Universe that predict a statistical anisotropy of the
cosmic microwave background (CMB) sky. We make use of WMAP9 maps deconvolved with …
