SETI at FAST in China
Tong-Jie Zhang, Bo-Lun Huang, Jian-Kang Li +4
Since the commencement of the first SETI observation in 2019, China's Search for Extraterrestrial Intelligence program has garnered momentum through domestic support and internatio…
A Search for Extraterrestrial Technosignatures in Archival FAST Survey Data Using a New Procedure
Yu-Chen Wang, Zhen-Zhao Tao, Zhi-Song Zhang +4
The "search for extraterrestrial intelligence" (SETI) commensal surveys aim to scan the sky to find possible technosignatures from the extraterrestrial intelligence (ETI). The miti…
SETI strategy with FAST fractality
Yi-Xuan Chen, Wen-Fei Liu, Zhi-Song Zhang +1
We applied the Koch snowflake fractal antenna in planning calibration of the Five-hundred-meter Aperture Spherical radio Telescope (FAST), hypothesizing second-order fractal primar…
First SETI Observations with China's Five-hundred-meter Aperture Spherical radio Telescope (FAST)
Zhi-Song Zhang, Dan Werthimer, Tong-Jie Zhang +16
The Search for Extraterrestrial Intelligence (SETI) attempts to address the possibility of the presence of technological civilizations beyond the Earth. Benefiting from high sensit…
Opportunities to Search for Extra-Terrestrial Intelligence with the Five-hundred-meter Aperture Spherical radio Telescope
Di Li, Vishal Gajjar, Pei Wang +31
The discovery of ubiquitous habitable extrasolar planets, combined with revolutionary advances in instrumentation and observational capabilities, has ushered in a renaissance in th…
Unit panel nodes detection by CNN on FAST reflector
Zhi-Song Zhang, Li-Chun Zhu, Wei Tang +1
The 500-meter Aperture Spherical Radio Telescope(FAST) has an active reflector. During the observation, the reflector will be deformed into a paraboloid of 300-meters. To improve i…
Fluctuation of the Hubble parameter
Xi-Bin Li, Hao-Feng Qin, Zhi-Song Zhang +1
We study the Hubble parameter in perturbed Friedmann universe and obtain an expression of the perturbed Hubble parameter . We derive the Hubble parameter po…
An improved method to test the Distance--Duality relation
Xi Yang, Hao-Ran Yu, Zhi-Song Zhang +1
Many researchers have performed cosmological-model-independent tests for the distance duality (DD) relation. Theoretical work has been conducted based on the results of these tests…
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…
Testing the Copernican Principle with Hubble Parameter
Zhi-Song Zhang, Tong-Jie Zhang, Hao Wang +1
Using the longitudinal expression of Hubble expansion rate for the general Lemaître-Tolman-Bondi (LTB) metric as a function of cosmic time, we examine the scale on which the Copern…
Estimations of the cosmological parameters from the observational variation of the fine structure constant
Zhong-Xu Zhai, Xian-Ming Liu, Zhi-Song Zhang +1
We present the constraints on the Quintessence scalar field model from the observational data of the variation of the fine structure constant obtained from Keck and VLT telescopes.…
