A New Test of Lorentz Invariance Violation: the Spectral Lag Transition of GRB 160625B
Jun-Jie Wei, Bin-Bin Zhang, Lang Shao +2
Possible violations of Lorentz invariance (LIV) have been investigated for a long time using the observed spectral lags of gamma-ray bursts (GRBs). However, these generally have re…
Impact of a locally measured H_0 on the interpretation of cosmic chronometer data
Jun-Jie Wei, Fulvio Melia, Xue-Feng Wu
Whereas many measurements in cosmology depend on the use of integrated distances or time, galaxies evolving passively on a time scale much longer than their age difference allow us…
An Improved Method to Measure the Cosmic Curvature
Jun-Jie Wei, Xue-Feng Wu
In this paper, we propose an improved model-independent method to constrain the cosmic curvature by combining the most recent Hubble parameter and supernovae Ia (SNe Ia) dat…
The HII Galaxy Hubble Diagram Strongly Favors over CDM
Jun-Jie Wei, Xue-Feng Wu, Fulvio Melia
We continue to build support for the proposal to use HII galaxies (HIIGx) and giant extragalactic HII regions (GEHR) as standard candles to construct the Hubble diagram at redshift…
New Limits on the Photon Mass with Radio Pulsars in the Magellanic Clouds
Jun-Jie Wei, Er-Kang Zhang, Song-Bo Zhang +1
A conservative constraint on the rest mass of the photon can be estimated under the assumption that the frequency dependence of dispersion from astronomical sources is mainly contr…
Gamma-ray burst cosmology: Hubble diagram and star formation history
Jun-Jie Wei, Xue-Feng Wu
We briefly introduce the disadvantages for Type Ia supernovae (SNe Ia) as standard candles to measure the Universe, and suggest Gamma-ray bursts (GRBs) can serve as a powerful tool…
