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…
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…
The FAST-SETI Milky Way Globular Cluster Survey I: A Pilot Multibeam On-the-Fly Search of Five Globular Clusters at L-Band
Bo-Lun Huang, Zhen-Zhao Tao, Tong-Jie Zhang +1
We report a narrowband technosignature search toward five Milky Way globular clusters (NGC 6171, NGC 6218, NGC 6254, NGC 6838, and IC 1276) using the Five-hundred-meter Aperture Sp…
The optimal Padé polynomial for reconstruction of luminosity distance based on 10-fold cross-validation
Bo Yu, Wenhu Liu, XiaoFeng Yang +2
The cosmography known as the Padé polynomials has been widely used in the reconstruction of luminosity distance, and the orders of Padé polynomials influence the reconstructed re…
Constraints on Baryon Density from the Effective Optical Depth of High-Redshift Quasars
Wen-Fei Liu, Yuan-Bo Xie, Zhi-E Liu +4
We present constraints on the baryonic matter density parameter, , within the framework of the CDM model. Our analysis utilizes observational data on the effective optica…
