Implications of primordial power spectra with statistical anisotropy on CMB temperature fluctuation and polarizations
Zhe Chang, Sai Wang
Both the Wilkinson Microwave Anisotropy Probe (WMAP) and Planck observations reported the hemispherical asymmetry of the cosmic microwave background (CMB) temperature fluctuation.…
CDM model with a scalar perturbation vs. preferred direction of the universe
Xin Li, Hai-Nan Lin, Sai Wang +1
We present a scalar perturbation for the CDM model, which breaks the isotropic symmetry of the universe. Based on the Union2 data, the least- fit of the scalar perturbed $Λ…
Finslerian perturbation for the CDM model
Xin Li, Sai Wang, Zhe Chang
We present Finslerian perturbation for the CDM model, which breaks the isotropic symmetry of the universe. The analysis on the Killing vectors shows that the Randers-Finsler spa…
Finslerian MOND versus the Strong Gravitational Lensing of the Early-type Galaxies
Zhe Chang, Ming-Hua Li, Xin Li +2
The gravitational lensing of Bullet Clusters and early-type galaxies pose serious challenges on the validity of MOND. Recently, Finslerian MOND, a generalization of MOND in the fra…
Quadrupole--octopole alignment of CMB related to primordial power spectrum with dipolar modulation in anisotropic spacetime
Zhe Chang, Xin Li, Sai Wang
The WMAP and Planck observations show that the quadrupole and octopole orientations of the CMB might align with each other. We reveal that the quadrupole--octopole alignment is a n…
Effects of spacetime anisotropy on the galaxy rotation curves
Zhe Chang, Ming-Hua Li, Xin Li +2
The observations on galaxy rotation curves show significant discrepancies from the Newtonian theory. This issue could be explained by the effect of the anisotropy of the spacetime.…
