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…

The Unified First law in "Cosmic Triad" Vector Field Scenario

Yi Zhang, Yungui Gong, Zong-Hong Zhu

In this letter, we try to apply the unified first law to the "cosmic triad" vector field scenario both in the minimal coupling case and in the non-minimalcoupling case. After trans…

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…
