Extinction Distributions in Nearby Star-resolved Galaxies. II. M33
Yuxi Wang, Yi Ren, Jian Gao +2
Extinction maps are essential for tracing interstellar dust and enabling accurate stellar population studies in galaxies. Here, a high-resolution extinction distribution of nearby…
The Spectroscopic and Photometric Study of a Star Cluster Sample in Andromeda Halo
Hongrui Gu, Zhou Fan, Bingqiu Chen +18
Halo star clusters serve as vital tracers for the formation and evolution of the Andromeda galaxy. In this work, we present physical parameters for 29 M31 halo star clusters, deriv…
A Tale of Two Dust Disks in Our Milky Way
Ruoyi Zhang, Haibo Yuan, Bingqiu Chen +4
Cosmic dust plays a vital role in stellar and galactic formation and evolution, but its three-dimensional structure in the Milky Way has remained unclear due to insufficient precis…
Variation of the 2175 Ã extinction feature in Andromeda galaxy
Bing Yan, Shu Wang, Jian Gao +2
Extinction curves contain key information on interstellar dust composition and size distribution, with the 2175 Ã bump being the most prominent feature. We analyze 20 sightlines to…
Observational Evidence of Dust Evolution in Supernova Remnants: Size Redistribution Toward Larger Grains in Early Sedov Phase
He Zhao, Bingqiu Chen, Jun Li
Recent observations have revealed that dust is widespread and abundant in galaxies up to , significantly influencing their appearance and spectral properties. I…
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…
