Gaussian processes reconstruction of dark energy from observational data
Ming-Jian Zhang, Hong Li
In the present paper, we investigate the dark energy equation of state using the Gaussian processes analysis method, without confining a particular parametrization. The reconstruct…
Physical condition for the slowing down of cosmic acceleration
Ming-Jian Zhang, Jun-Qing Xia
The possible slowing down of cosmic acceleration was widely studied. However, the imposition of dark energy parametrization brought some tensions. In our recent paper, we test this…
Testing dark energy models with data
Jing-Zhao Qi, Ming-Jian Zhang, Wen-Biao Liu
is a diagnostic approach to distinguish dark energy models. However, there are few articles to discuss what is the distinguishing criterion. In this paper, firstly we smoot…
What do we know about cosmography
Ming-Jian Zhang, Hong Li, Jun-Qing Xia
In the present paper, we investigate the cosmographic problem using the bias-variance trade-off. We find that both the z-redshift and the -redshift can present a small b…
Dynamical evolution of quintessence cosmology in a physical phase space
Jing-Zhao Qi, Ming-Jian Zhang, Wen-Biao Liu
The phase space analysis of cosmological parameters and is given. Based on this, the well-known quintessence cosmology is studied with an exponential potential $V(ϕ)=V_…
Observational constraint on the varying speed of light theory
Jing-Zhao Qi, Ming-Jian Zhang, Wen-Biao Liu
The varying speed of light (VSL) theory is controversial. It succeeds in explaining some cosmological problems, but on the other hand it is excluded by mainstream physics because i…
Transient acceleration in gravity
Jing-Zhao Qi, Rong-Jia Yang, Ming-Jian Zhang +1
Recently a gravity based on the modification of the teleparallel gravity was proposed to explain the accelerated expansion of the universe without the need of dark energy. W…
Observational constraint on the interacting dark energy models including the Sandage-Loeb test
Ming-Jian Zhang, Wen-Biao Liu
Two types of interacting dark energy models are investigated using the type Ia supernova (SNIa), observational data (OHD), cosmic microwave background (CMB) shift parameter…
Power of the redshift drift on cosmological models and expansion history
Ming-Jian Zhang, Wen-Biao Liu
We investigate the power of the velocity drift () on cosmological parameters and expansion history with observational Hubble data (OHD), type Ia supernova (SNIa). We estimate t…
Reconstruction and constraining of the jerk parameter from OHD and SNe Ia observations
Zhong-Xu Zhai, Ming-Jian Zhang, Zhi-Song Zhang +2
Compared with the plentiful researches of the Hubble parameter and deceleration factor, the third time derivative of the scale factor in the FRW cosmology, namely, the jerk…
Cosmological constraints on holographic dark energy models under the energy conditions
Ming-Jian Zhang, Cong Ma, Zhi-Song Zhang +2
We study the holographic and agegraphic dark energy models without interaction using the latest observational Hubble parameter data (OHD), the Union2.1 compilation of type Ia super…
