GSED: The Galactic Stellar Extinction Database
Baisong Zhang, Bingqiu Chen, Dongwei Fan +9
Reliable extinction correction is essential for nearly all astrophysical studies within the Galaxy. We present the Galactic Stellar Extinction Database (GSED, https://nadc.china-vo…
SN 2024aecx: A double-peaked rapidly evolving Type IIb supernova at 11 Mpc
Xingzhu Zou, Brajesh Kumar, Rishabh Singh Teja +28
We present the results of low-resolution spectroscopic and densely sampled multi-band photometric follow-up of supernova (SN) 2024aecx. The SN was discovered in the spiral galaxy N…
The Milky Way is a less massive galaxy--new estimates of the Milky Way's local and global stellar masses
Jianhui Lian, Tao Wang, Qikang Feng +2
Stellar mass is the most fundamental property of a galaxy. While it has been robustly measured for millions of external galaxies, it remains poorly constrained for the Milky Way be…
Multiwavelength Analysis of GRB 250101A: From Gamma-ray Prompt Emission to Optical Afterglow
Guowang Du, Yehao Cheng, Yuan-Pei Yang +15
The interaction between the relativistic jet and the circumburst medium produces a multiwavelength afterglow of a gamma-ray burst (GRBs). In this work, we present multiwavelength p…
Identification of Star Clusters in M31 from PAndAS Images Based on Deep Learning
Baisong Zhang, Bingqiu Chen, Haibo Yuan +5
The identification of star clusters holds significant importance in studying galaxy formation and evolution history. However, the task of swiftly and accurately identifying star cl…
Simultaneous Multiband Photometry of the Early Optical Afterglow of GRB 240825A with Mephisto
Yehao Cheng, Yu Pan, Yuan-Pei Yang +19
Gamma-ray bursts (GRBs) are the most luminous transients in the universe. The interaction of the relativistic jet with the circumburst medium produces an afterglow and generates mu…
