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…
Recalibration of the Landolt UBVRI Standard Stars and the Generation of 5.4 Million New UBVRI Standard Stars using LAMOST and Gaia
Bowen Huang, Haibo Yuan, Kai Xiao +1
We present an independent validation and recalibration of the Landolt 2013 (celestial equator and ) and 2016 () standard stars in the Johnson $U…
A Comprehensive All-Sky Catalog of 3345 Molecular Clouds from Three-dimensional Dust Extinction
Tao Wang, Haibo Yuan, Bingqiu Chen +4
Understanding the distribution and properties of molecular clouds is crucial for tracing the structure and evolution of the interstellar medium and the large-scale morphology of th…
An all-sky 3D dust map Based on Gaia and LAMOST
Tao Wang, Haibo Yuan, Bingqiu Chen +6
We present a comprehensive 3D dust reddening map covering the entire Milky Way, constructed by combining reddening estimates based on LAMOST low-resolution spectra (E(BV)$_{\rm…
Additional Evidence for the Existence of a Primordial Disk System
Shuai Xu, Haibo Yuan, Bowen Huang +7
The origin of very metal-poor (VMP; [Fe/H] ) stars on planar orbits has been the subject of great attention since their first discovery. However, prior to the release of…
