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…

Testing the Isotropy of the Universe with Type Ia Supernovae
L. Campanelli, P. Cea, G. L. Fogli +1
We analyze the magnitude-redshift data of type Ia supernovae included in the Union and Union2 compilations in the framework of an anisotropic Bianchi type I cosmological model and…
