Comparison between hemisphere comparison method and dipole-fitting method in tracing the anisotropic expansion of the Universe use the Union2 dataset
Zhe Chang, Hai-Nan Lin
Type-Ia supernovae (SNe Ia) are often used as the standard candles to probe the anisotropic expansion of the Universe. In this paper, we make a comprehensive comparison between the…
Gamma-ray polarization of synchrotron-self-Compton process from a highly relativistic jet
Zhe Chang, Hai-Nan Lin
The high polarization observed in the prompt phase of some gamma-ray bursts (GRBs) arouses extensive studies on the emission mechanism. In this paper, we investigate the polarizati…
Constraining the Anisotropy of the Universe from Supernovae and Gamma-ray Bursts
Zhe Chang, Xin Li, Hai-Nan Lin +1
Recently, an anisotropic cosmological model was proposed. An arbitrary 1-form, which picks out a privileged axis in the universe, was added to the Friedmann-Robertson-Walker line e…
The change of GRB polarization angles in the magnetic-dominated jet model
Zhe Chang, Hai-Nan Lin
The polarimetric measurement on the prompt phase of GRB 100826A shows that the polarization angle changes between two adjacent time intervals. We will show that t…
Constraining anisotropy of the universe from different groups of type-Ia supernovae
Zhe Chang, Xin Li, Hai-Nan Lin +1
Recent released Planck data and other astronomical observations show that the universe may be anisotropic on large scales. Inspired by this, anisotropic cosmological models have be…
