A new analytical approximation of luminosity distance by optimal HPM-Padé technique
Bo Yu, Jian-Chen Zhang, Tong-Jie Zhang +1
By the use of homotopy perturbation method-Padé (HPM-Padé) technique, a new analytical approximation of luminosity distance in the flat universe is proposed, which has the advantag…
Computing the luminosity distance via optimal homotopy perturbation method
Bo Yu, Zi-Hua Wang, De-Zi Liu +1
We propose a new algorithm for computing the luminosity distance in the flat universe with a cosmological constant based on Shchigolev's homotopy perturbation method, where the opt…
New Constraints on Anisotropic Rotation of CMB Polarization
Mingzhe Li, Bo Yu
The coupling of a scalar field to electromagnetic field via the Chern-Simons term will rotate the polarization directions of the cosmic microwave background radiation. The rotation…
Gamma-ray Burst Luminosity Relations: Two-dimensional versus Three-dimensional Correlations
Bo Yu, Shi Qi, Tan Lu
The large scatters of luminosity relations of gamma-ray bursts (GRBs) have been one of the most important reasons that prevent the extensive applications of GRBs in cosmology. In t…
Standardization, Distance, Host Galaxy Extinction of Type Ia Supernova and Hubble Diagram from the Flux Ratio Method
Bo Yu, Gui-Lin Yang, Tan Lu
In this paper we generalize the flux ratio method Bailey et al. (2009) to the case of two luminosity indicators and search the optimal luminosity-flux ratio relations on a set of s…
