Helium-4 Synthesis in an Anisotropic Universe
Leonardo Campanelli
We calculate the 4He abundance in a universe of Bianchi type I whose cosmic anisotropy is dynamically generated by a fluid with anisotropic equation of state. Requiring that the re…
Galaxy cluster number count data constraints on cosmological parameters
L. Campanelli, G. L. Fogli, T. Kahniashvili +2
[Abridged] We use data on massive galaxy clusters ( within a comoving radius of $R_{\rm cluster} = 1.5 h^{-1}\Mpc$) in the redshi…
Cosmic Parallax in Ellipsoidal Universe
L. Campanelli, P. Cea, G. L. Fogli +1
The detection of a time variation of the angle between two distant sources would reveal an anisotropic expansion of the Universe. We study this effect of "cosmic parallax" within t…
Anisotropic dark energy and ellipsoidal universe
L. Campanelli, P. Cea, G. L. Fogli +1
A cosmological model with anisotropic dark energy is analyzed. The amount of deviation from isotropy of the equation of state of dark energy, the skewness δ, generates an anisotrop…
