The Extinction Distance of Supernova Remnants in Combination with the CO Line Measurements
Zhe Zhang, Jun Li, Biwei Jiang +2
Accurate distance measurements to supernova remnants (SNRs) are crucial for understanding their physical properties and evolution. We present a novel method that combines CO line o…
An Enhanced Sample of Galactic Red Supergiants Reveals Spiral Structures
Zehao Zhang, Biwei Jiang, Yi Ren
Red supergiants (RSGs), representing a kind of massive young stellar population, have rarely been used to probe the structure of the Milky Way, mainly due to the long-standing scar…
The structural and kinematical properties of NGC 5634, a globular cluster associated with the Sagittarius dwarf galaxy?
Shouzhi Wang, Jundan Nie, Biwei Jiang +3
We investigate the origin of NGC 5634 through a comprehensive analysis of its morphology, kinematics and dynamics. Utilizing data from the DESI Legacy Survey, we refined its fundam…
Massive Acquisition of Ultraviolet Color Excess Information from GALEX and UVOT Bands
Dongliang Yang, Mingxu Sun, Biwei Jiang +4
This study employs stellar parameters from spectroscopic surveys and Zhang et al. based on Gaia XP spectra, along with photometric data from GALEX, UVOT, and Gaia, to obtain extens…
The Multi-wavelength Extinction Law and its Variation in the Coalsack Molecular Cloud Based on the Gaia, APASS, SMSS, 2MASS, GLIMPSE, and WISE Surveys
Juan Deng, Shu Wang, Biwei Jiang +1
Accurate interpretation of observations relies on the interstellar dust extinction law, which also serves as a powerful diagnostic for probing dust properties. In this study, we in…
A New Approach to Identifying Red Supergiant Stars in Metal-poor Galaxies: A Case Study of NGC 6822
Zhiwen Li, Ming Yang, Biwei Jiang +1
A complete sample of red supergiant stars (RSGs) is important for studying their properties. Identifying RSGs in extragalatic field first requires removing the Galactic foreground…
