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…
Interactions in Dark Energy Models
Yi Zhang, Hui Li, Yungui Gong +1
We perform a full dynamical analysis by considering the interactions between dark energy and radiation, and dark energy and dark matter. We find that the interaction helps alleviat…
A quantitative criteria for the coincidence problem
Hongsheng Zhang, Heng Yu, Zong-Hong Zhu +1
The cosmic coincidence problem is a serious challenge to dark energy model. We suggest a quantitative criteria for judging the severity of the coincidence problem. Applying this cr…
Growth factor parametrization in curved space
Yungui Gong, Mustapha Ishak, Anzhong Wang
The growth rate of matter perturbation and the expansion rate of the Universe can be used to distinguish modified gravity and dark energy models in explaining cosmic acceleration.…
