Segmentation and Celestial Mapping of Unobservable Regions in Nighttime All-sky Images for the Mephisto Observations
Jian Cui, Guo-Wang Du, Xin-Zhong Er +5
Accurate identification of unobservable regions in nighttime is essential for autonomous scheduling and data quality control in observations.Traditional methods-such as infrared se…
GRB 240825A: Early Reverse Shock and Its Physical Implications
Chao Wu, Yun Wang, Hua-Li Li +84
Early multiwavelength observations offer crucial insights into the nature of the relativistic jets responsible for gamma-ray bursts and their interaction with the surrounding mediu…
SN 2024gy: Multi-epoch Spectroscopic Features Suggestive of Delayed Detonation in a Type Ia Supernova
Liping Li, Zhenyu Wang, Jialian Liu +28
We present photometric and spectroscopic observations of SN 2024gy, a Type Ia supernova (SN Ia) exhibiting high-velocity features (HVFs) in its early-time spectra. This SN reaches…
The Kinematic Signature of the Warp and Waves in the Milky Way Disk
Weixiang Sun, Han Shen, Biwei Jiang +1
Using over 170,000 red clump (RC) stars selected from LAMOST and APOGEE, we conduct a detailed analysis of the stellar as a function of (or ) across differen…
Photometric metallicities of 0.8 million KiDS stars
Bao-Kun Sun, Bing-Qiu Chen, Xiao-Wei Liu
Accurate determinations of metallicity for large, complete stellar samples are essential for advancing various studies of the Milky Way. In this paper, we present a data-driven alg…
The Age-velocity Dispersion Relations of the Galactic Disk as Revealed by the LAMOST-Gaia Red Clump Stars
Weixiang Sun, Han Shen, Biwei Jiang +1
Using nearly 230,000 red clump (RC) stars selected from LAMOST and Gaia, we conduct a comprehensive analysis of the stellar age-velocity dispersion relations (AVRs) for various dis…
