An anti-correlation between barycentre offsets and velocity dispersion for highest overdensity subhalos in cosmological simulations
Ming-Hua Li, Hai-Nan Lin
In this paper, we use two hydrodynamic simulations to study the barycentre offsets between the entire halo and the gas or dark matter subhalo with largest overdensity…
New constraints on the distance duality relation from the local data
Hai-Nan Lin, Ming-Hua Li, Xin Li
The cosmic distance duality relation (DDR), which connects the angular diameter distance and luminosity distance through a simple formula , is an impor…
Correlation between centre offsets and gas velocity dispersion of galaxy clusters in cosmological simulations
Ming-Hua Li, Weishan Zhu, Dong Zhao
The gas is the dominant component of baryonic matter in most galaxy groups and clusters. The spatial offsets of gas centre from the halo centre could be an indicator of the dynamic…
Testing the homogeneity of the Universe using gamma-ray bursts
Ming-Hua Li, Hai-Nan Lin
In this paper, we study the homogeneity of the GRB distribution using a subsample of the Greiner GRB catalogue, which contains 314 objects with redshift (244 of them disc…
The Two-Point Correlation Function of Gamma-ray Bursts
Ming-Hua Li, Hai-Nan Lin
In this paper, we examine the spacial distribution of gamma-ray bursts (GRBs) using a sample of 373 objects. We subdivide the GRB data into two redshift intervals over the redshift…
Inflation in de Sitter spacetime and CMB large scales anomaly
Dong Zhao, Ming-Hua Li, Ping Wang +1
The influence of cosmological constant type dark energy in the early universe is investigated. This is accommodated by a new dispersion relation in de Sitter spacetime. We perform…
Investigation of homogeneity and matter distribution on large scales using large quasar groups
Ming-Hua Li, Zhi-Bing Li
We use 12 large quasar group (LQG) samples to investigate the homogeneity of Universe ( denotes the redshift). We calculate the bias factor and th…
CosmoMC Installation and Running Guidelines
Ming-Hua Li, Ping Wang, Zhe Chang +1
CosmoMC is a Fortran 95 Markov-Chain Monte-Carlo (MCMC) engine to explore the cosmological parameter space, plus a Python suite for plotting and presenting results (see http://cosm…
Constraints on Bose-Einstein-condensed Axion Dark Matter from The HI Nearby Galaxy Survey data
Ming-Hua Li, Zhi-Bing Li
One of the leading candidates for dark matter is axion or axion-like particle in a form of Bose-Einstein condensate (BEC). In this paper, we present an analysis of 17 high-resoluti…
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…
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.…
Finsler geometric perspective on the bulk flow in the universe
Zhe Chang, Ming-Hua Li, Sai Wang
Astronomical observations showed that there may exist a bulk flow with peculiar velocities in the universe, which contradicts with the (Λ)CDM model. The bulk flow reveals that the…
Cosmological model with local symmetry of very special relativity and constraints on it from supernovae
Zhe Chang, Ming-Hua Li, Xin Li +1
Based on Cohen \& Glashow's very special relativity [A. G. Cohen and S. L. Glashow, Phys. Rev. Lett. {\bf 97} (2006) 021601], we propose an anisotropic modification to the Friedman…
Galaxies Rotation Curves in the Grumiller's Modified Gravity
Hai-Nan Lin, Ming-Hua Li, Xin Li +1
The effective potential in the Grumiller's modified gravity [D. Grumiller, Phys. Rev. Lett {\bf 105}, 211303 (2010)] includes the Newtonian potential and a Rindler term. The fittin…
Finslerian MOND vs. observations of Bullet Cluster 1E0657-558
Xin Li, Ming-Hua Li, Hai-Nan Lin +1
It is known that theory of MOND with spherical symmetry cannot account for the convergence -map of Bullet Cluster 1E0657-558. In this paper, we try to set up a Finslerian MOND,…
Generalization of Rindler Potential at Cluster Scales in Randers-Finslerian Spacetime: a Possible Explanation of the Bullet Cluster 1E0657-558?
Zhe Chang, Ming-Hua Li, Hai-Nan Lin +1
The data of the Bullet Cluster 1E0657-558 released on November 15, 2006 reveal that the strong and weak gravitational lensing convergence -map has an offset from the -ma…
An Inflationary Scenario Taking into Account of Possible Dark Energy Effects in the Early Universe
Zhe Chang, Ming-Hua Li, Sai Wang +1
We investigate the possible effect of cosmological-constant type dark energy during the inflation period of the early universe. This is accommodated by a new dispersion relation in…
Constraints from Type IA Supernovae on λ-CDM Model in Randers-Finsler Space
