Periodic Radio Technosignature Search toward 3I/ATLAS with FAST
Jian-Kang Li, Zhen-Zhao Tao, Tong-Jie Zhang +1
3I/ATLAS, the third confirmed interstellar object discovered in the Solar System, provides a unique opportunity for targeted technosignature searches. We report a periodic radio te…
First Lunar Farside SETI Observations for Periodic Signals with the Low-frequency Radio Spectrometer of Chang'E-4 Mission
Jian-Kang Li, Zhen-Zhao Tao, Bo-Lun Huang +6
Chang'E-4 (CE4), the first mission to soft-land on the lunar farside, provides a unique opportunity for astronomical observations from an environment shielded from terrestrial radi…
A Wavelet-Integrated Search Pipeline for Narrowband Technosignatures in FAST Observations of 33 Exoplanet Systems
Zi-Qi Li, Jian-Kang Li, Zhe-Wei Luo +14
Building on prior FAST targeted and blind SETI campaigns toward 33 exoplanet systems, we introduce a wavelet-integrated search pipeline for narrowband technosignature candidates in…
Narrowband Radio Technosignature Search toward 3I/ATLAS with FAST
Jian-Kang Li, Zhen-Zhao Tao, Tong-Jie Zhang
3I/ATLAS is the third confirmed interstellar object passing through the Solar System. In this work, we conduct narrowband radio technosignature search toward 3I/ATLAS using the Fiv…
An Improved Machine Learning Approach for Radio Frequency Interference Mitigation in FAST-SETI Survey Archival Data
Li-Li Zhao, Xiao-Hang Luan, Xin Chao +6
The search for extraterrestrial intelligence (SETI) commensal surveys aim to scan the sky to detect technosignatures from extraterrestrial life. A major challenge in SETI is the ef…
Dual-Backend Multibeam Position Switching Targeted SETI Observations toward Nearby Active Planet-Hosting Systems with FAST
Jian-Kang Li, Zhen-Zhao Tao, Pei Wang +1
The Five-hundred-meter Aperture Spherical Telescope (FAST), the world's largest single-dish radio telescope, lists the search for extraterrestrial intelligence (SETI) as one of its…
Polarization Properties of the Electromagnetic Response to High-frequency Gravitational Wave
Jian-Kang Li, Wei Hong, Tong-Jie Zhang
Electromagnetic waves (EMWs) can be generated by gravitational waves (GWs) within a magnetic field via the Gertsenshtein effect. The conversion probability between GWs and EMWs can…
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…
The most sensitive SETI observations toward Barnard's star with FAST
Zhen-Zhao Tao, Bo-Lun Huang, Xiao-Hang Luan +4
Search for extraterrestrial intelligence (SETI) has been mainly focused on nearby stars and their planets in recent years. Barnard's star is the second closest star system to the s…
Polarization Criterion in Targeted SETI Observation
Jian-Kang Li, Yu Chen, Zhen-Zhao Tao +5
In this paper, we propose a novel method for distinguishing extraterrestrial intelligence (ETI) signals from radio frequency interference (RFI) by leveraging polarization features.…
Drift Rates of Narrowband Signals in Long-term SETI Observations for Exoplanets
Jian-Kang Li, Haichen Zhao, Zhenzhao Tao +2
The Doppler shift of a radio signal is caused by the relative motion between the transmitter and receiver. The change in frequency of the signal over time is called drift rate. In…
