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…
Gamma-ray burst polarization via Compton scattering process
Zhe Chang, Hai-Nan Lin, Yunguo Jiang
Synchrotron radiation and Compton scattering are widely accepted as the most likely emission mechanisms of some astrophysical phenomena, such as gamma-ray bursts (GRBs) and active…
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…
Polarization of photons scattered by electrons in any spectral distribution
Zhe Chang, Yunguo Jiang, Hai-Nan Lin
Based on the quantum electrodynamics, we present a generic formalism of the polarization for beamed monochromatic photons scattered by electrons in any spectral distribution. The f…
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.…
Gamma-ray polarization induced by cold electrons via Compton processes
Zhe Chang, Yunguo Jiang, Hai-Nan Lin
The polarization measurement is an important tool to probe the prompt emission mechanism in gamma-ray bursts (GRBs). The synchrotron photons can be scattered by cold electrons in t…
