Testing cosmic opacity from SNe Ia and Hubble parameter through three cosmological-model-independent methods
Kai Liao, Zhengxiang Li, Jing Ming +1
We use the newly published 28 observational Hubble parameter data () and current largest SNe Ia samples (Union2.1) to test whether the universe is transparent. Three cosmolog…
A unification of RDE model and XCDM model
Kai Liao, Zong-Hong Zhu
In this Letter, we propose a new generalized Ricci dark energy (NGR) model to unify Ricci dark energy (RDE) and XCDM. Our model can distinguish between RDE and XCDM by introducing…
A multi-wavelength study of the gravitational lens COSMOS J095930+023427
Shuo Cao, Giovanni Covone, Maurizio Paolillo +1
We present a multi-wavelength study of the gravitational lens COSMOS J095930+023427 (z=0.89), together with the associated galaxy group located at along the line of sigh…
Metal Abundance and Kinematical Properties of M81 Globular Cluster System
Jun Ma, Zhenyu Wu, Tianmeng Zhang +7
In this paper, we presented metal abundance properties of 144 M81 globular clusters. These globulars consist of the largest globular cluster sample in M81 till now. Our main result…
Testing the interaction model with cosmological data and gamma-ray bursts
Yu Pan, Shuo Cao, Yungui Gong +2
We use the new gamma-ray bursts (GRBs) data, combined with the baryon acoustic oscillation(BAO) observation from the spectroscopic Sloan Digital Sky Survey (SDSS) data release, the…
Observational constraints on cosmic neutrinos and dark energy revisited
Xin Wang, Xiao-Lei Meng, Tong-Jie Zhang +5
Using several cosmological observations, i.e. the cosmic microwave background anisotropies (WMAP), the weak gravitational lensing (CFHTLS), the measurements of baryon acoustic osci…
