Tate cohomology of unipotent cuspidal representations of finite groups of Lie type
Sabyasachi Dhar
Let be a prime and be an algebraic closure of the finite field with elements. Let be a connected reductive algebraic group over , and let be a…
Identifying and Determining Atmospheric Parameters of BHB Stars Based on LAMOST DR11
Xiao-Long Wang, Wen-Yuan Cui, Jie Ju +4
Large catalogs of blue horizontal-branch (BHB) stars are essential for studying substructures and kinematics of the Galactic halo. And accurate determination of atmospheric paramet…
Investigation of projected rotational velocities of Be-type stars in LAMOST DR7
Zhicun Liu, Jiao Li, Jiaming Liu +3
Stellar rotation plays a key role in the transfer of angular momentum, and a large sample of Be-type stars with reliable projected rotational velocities is crucial for understandin…
Radial Distributions of Star Formation and Gas-phase Metallicity in Spiral-Elliptical Galaxy Pairs
Cailu Shi, Shuai Feng, Shiyin Shen +3
Using integral field spectroscopy from SDSS-IV MaNGA, we investigate the radial distributions of star formation rate (SFR) and gas-phase metallicity in spiral galaxies that reside…
Identification of OB associations using the LAMOST-Gaia OB star sample
Zhicun Liu, Xiao-Long Wang, Wenyuan Cui +7
OB associations, as an intermediate stage between Galactic clusters and field stars, play an important role in understanding the star formation process, early stellar evolution, an…
Identification of BHB stars using Synthetic SkyMapper colors from Gaia XP spectra
Guozhen Hu, Yang Huang, Wenyuan Cui +9
Blue horizontal-branch (BHB) stars are ideal tracers for mapping the structure of Galactic stellar halo. Traditionally, BHB sample stars are built from large-scale spectroscopic su…
Investigating lower limit of metallicity for Galactic thin disk
Guozhen Hu, Zhengyi Shao, Erbil Gugercinoglu +1
We explore the metal-poor regime of the Galactic disk on the distribution of stars in the [/M]- plane, to identify the most metal-poor thin disk (MPTnD) stars belonging to…
Diffuse Ionized Gas in the Anti-center of the Milky Way
Shiming Wen, Wei Zhang, Lin Ma +10
Using data from the LAMOST Medium-Resolution Spectroscopic Survey of Nebulae, we create a sample of 17,821 diffuse ionized gas (DIG) spectra in the anti-center region of the Milky…
The Value-added Catalog of OB Stars in LAMOST DR7
Zhicun Liu, Wenyuan Cui, Jiajia Gu +4
In this work, we update the catalog of OB stars based on the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) data release 7 and modified the OB stars selection c…
