Gaia DR3 Limits on Stellar Engine Technosignatures in Nearby Stars
Bo-Lun Huang, Zhen-Zhao Tao, Tong-Jie Zhang +1
An operating stellar engine that transfers momentum to its host star could produce an approximately persistent transverse acceleration during the Gaia Data Release 3 (DR3) observin…
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…
A Calibrated Bayesian Search for Potential Chemical Technosignatures in Polluted White Dwarf
Bo-Lun Huang, Zhen-Zhao Tao, Tong-Jie Zhang
We present a meteorite-calibrated Bayesian framework for searching archival abundance records for chemical technosignatures--operationally, compositional patterns better explained…
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…
Phase-Space Crystallization in Galactic Globular Clusters: A Gaia-Based Metric and Implications for Technosignature Searches
Bo-Lun Huang, Zhen-Zhao Tao, Tong-Jie Zhang
We develop a model-independent framework to quantify phase-space "crystallization", the degree of ordered radial and kinematic substructure, in 79 Galactic globular clusters using…
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…
SETI Observations of k-Hz Periodic Radio Signals from Five Nearby Stars with FAST at L Band
Yu Hu, Bo-Lun Huang, Vishal Gajjar +3
We report a radio SETI search for periodic, kHz-wide signals from five of the nearest stars observable with the Five-hundred-meter Aperture Spherical radio Telescope (FAST). Using…
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…
WISE/CatWISE Constraints on Dysonian Waste-Heat Technosignatures in Nearby Galaxies
Bo-Lun Huang, Zhen-Zhao Tao, Tong-Jie Zhang
We search for galaxy-scale (Dysonian) waste heat in the mid-infrared using WISE. Starting from the 2MASS Redshift Survey (2MRS), we cross-match to CatWISE2020 and AllWISE, apply st…
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…
A Deep SETI Search for Technosignatures in the TRAPPIST-1 System with FAST
Guang-Yuan Song, Zhen-Zhao Tao, Bo-Lun Huang +3
The Five-hundred-meter Aperture Spherical Telescope (FAST) is the world's largest single-dish radio telescope, and the search for extraterrestrial intelligence (SETI) is one of its…
Multibeam SETI Observations toward Nearby M dwarfs with FAST
Xiao-Hang Luan, Bo-Lun Huang, Zhen-Zhao Tao +3
The search for extraterrestrial intelligence (SETI) targeted searches aim to observe specific areas and objects to find possible technosignatures. Many SETI researches have focused…
