A Non-parametric Reconstruction of the Hubble Parameter Based on Radial Basis Function Neural Networks
Jian-Chen Zhang, Yu Hu, Kang Jiao +5
Accurately measuring the Hubble parameter is vital for understanding the expansion history and properties of the universe. In this paper, we propose a new method that supplements t…
Sensitive Multi-beam Targeted SETI Observations towards 33 Exoplanet Systems with FAST
Zhen-Zhao Tao, Hai-Chen Zhao, Tong-Jie Zhang +19
As a major approach to looking for life beyond the Earth, the search for extraterrestrial intelligence (SETI) is committed to detecting technosignatures such as engineered radio si…
Model-independent reconstruction of the cosmological scale factor as a function of lookback time
Jian-Chen Zhang, Jing Zheng, Tong-Jie Zhang
We present a model-independent method of reconstructing scale factor against lookback time from the Observational Hubble parameter Data (OHD). The reconstruction method is independ…
A new analytical approximation of luminosity distance by optimal HPM-Padé technique
Bo Yu, Jian-Chen Zhang, Tong-Jie Zhang +1
By the use of homotopy perturbation method-Padé (HPM-Padé) technique, a new analytical approximation of luminosity distance in the flat universe is proposed, which has the advantag…
Model-independent measurement of the Hubble Constant and the absolute magnitude of Type Ia Supernovae
Jian-Chen Zhang, Kang Jiao, Tong-Jie Zhang
In this work, we propose a cosmological model-independent and non-local method to constrain the Hubble Constant . Inspired by the quasi cosmological model-independent and $H_0…
