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…
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…
Unveiling a young thick disk in the Milky Way
Jianhui Lian, Min Du, Shuai Lu +5
The thickness of a galaxy's disk provides a valuable probe of its formation and evolution history. Observations of the Milky Way and local galaxies have revealed an ubiquitous disk…
The Stellar Disk Structure Rrevealed by the Mono-age Populations of the LAMOST Red Clump Sample
Zheng Yu, Bingqiu Chen, Jianhui Lian +2
Understanding the structure of the Galactic disk is crucial for understanding the formation and evolutionary history of the Milky Way. This study examines the structure of the Gala…
