Cosmological Tests Using the Angular Size of Galaxy Clusters
Jun-Jie Wei, Xue-Feng Wu, Fulvio Melia
We use measurements of the galaxy-cluster angular size versus redshift to test and compare the standard model (LCDM) and the R_h=ct Universe. We show that the latter fits the data…
A Comparison of Cosmological Models Using Strong Gravitational Lensing Galaxies
Fulvio Melia, Jun-Jie Wei, Xue-Feng Wu
Strongly gravitationally lensed quasar-galaxy systems allow us to compare competing cosmologies as long as one can be reasonably sure of the mass distribution within the intervenin…
Distributions of Gamma-Ray Bursts and Blazars in the Plane and Possible Implications for their Radiation Physics
Fen Lyu, En-Wei Liang, Yun-Feng Liang +5
We present a spectral analysis for a sample of redshift known GRBs observed with {\em Fermi}/GBM. Together with the results derived from our systematical spectral energy distributi…
A Comparison of Cosmological Models Using Time Delay Lenses
Jun-Jie Wei, Xue-Feng Wu, Fulvio Melia
The use of time-delay gravitational lenses to examine the cosmological expansion introduces a new standard ruler with which to test theoretical models. The sample suitable for this…
Variability of the giant X-ray bump in GRB 121027A and possible origin
Shu-Jin Hou, He Gao, Tong Liu +7
The particular giant X-ray bump of GRB 121027A triggered by \emph{Swift} is quite different from the typical X-ray flares in gamma-ray bursts. There exhibit four parts of the obser…
Time evolution of flares in GRB 130925A: jet precession in black hole accretion system
Shu-Jin Hou, Tong Liu, Wei-Min Gu +4
GRB 130925A, composed of three gamma-ray emission episodes and a series of orderly flares, has been detected by , Fermi, Konus-, and . If the third weakest g…
