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…
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…
Exploring the Wolf Approach to Constraining NIR Extinction Laws in the Corona Australis Molecular Cloud
Botao Jiang, Jun Li, Xi Chen
The viability of the star count (Wolf) method is assessed as a means of constraining the near-infrared (NIR) extinction law toward the Corona Australis molecular cloud. Using deep…
The Flattest Infrared Extinction Curve in Four Isolated Dense Molecular Cloud Cores
Jun Li, Bingqiu Chen, Biwei Jiang +3
The extinction curve of interstellar dust in the dense molecular cloud cores is crucial for understanding dust properties, particularly size distribution and composition. We invest…
The Ultraviolet Extinction Map and Dust Property at High Galactic Latitude
Mingxu Sun, Biwei Jiang, Haibo Yuan +1
Extinction in ultraviolet is much more significant than in optical or infrared, which can be very informative to precisely measure the extinction and understand the dust properties…
