Scalable Stellar Parameter Inference Using Python-based LASP: From CPU Optimization to GPU Acceleration
Jun-Chao Liang, Yin-Bi Li, A-Li Luo +13
To enhance the efficiency, scalability, and cross-survey applicability of stellar parameter inference in large spectroscopic datasets, we present a modular, parallelized Python fra…
Systematic search for blue hyper-velocity stars from LAMOST survey
Yongkang Sun, Yang Huang, Jifeng Liu +6
Hypervelocity stars (HVSs) represent a unique class of objects capable of escaping the gravitational pull of the Milky Way due to extreme acceleration events, such as close encount…
Ionized gas metallicity of the strong [OIII]λ emission-line compact galaxies in the LAMOST survey
Siqi Liu, A-Li Luo, Wei Zhang +2
This article reports a sample of 1830 strong [O III] λ5007 emission-line compact galaxies discovered with the LAMOST spectroscopic survey and the photometric catalog of SDSS. We ne…
The HI gas fraction scaling relation of the Green Pea galaxies
Siqi Liu, A-Li Luo, Wei Zhang +3
Green Pea galaxies are compact galaxies with high star formation rates. However, limited samples of Green Pea galaxies have HI 21 cm measurements. Whether the HI gas fraction f_{HI…
Estimation of stellar atmospheric parameters from LAMOST DR8 low-resolution spectra with 20SNR30
Xiangru Li, Zhu Wang, Si Zeng +4
The accuracy of the estimated stellar atmospheric parameter decreases evidently with the decreasing of spectral signal-to-noise ratio (SNR) and there are a huge amount of this kind…
The First Data Release (DR1) of the LAMOST general survey
A. -L. Luo, Y. -H. Zhao, G. Zhao +140
The Large sky Area Multi-Object Spectroscopic Telescope (LAMOST) General Survey is a spectroscopic survey that will eventually cover approximately half of the celestial sphere and…
