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…
Bivariate Luminosity Function of Galaxy Pairs
Shuai Feng, Shi-Yin Shen, Fang-Ting Yuan +8
We measure the bivariate luminosity function (BLF) of galaxy pairs and use it to probe and characterize the galaxy-galaxy interaction between pair members. The galaxy pair sample i…
The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) Quasar Survey: the 4th and 5th Data Release
Su Yao, Xue-Bing Wu, Y. L. Ai +15
We present the Data Release 4&5 quasar catalog from the quasar survey by Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), which includes quasars observed between…
Double-peaked Narrow Emission-line Galaxies in LAMOST Survey
M. X. Wang, A. L. Luo, Y. H. Song +10
We outline a full-scale search for galaxies exhibiting double-peaked profiles of promi- nent narrow emission lines, motivated by the prospect of finding objects related to merging…
Spectroscopic Identification and Chemical Distribution of HII Regions in the Galactic Anti-center Area from LAMOST
Li-Li Wang, A-Li Luo, Wen Hou +4
We spectroscopically identify 101 Galactic HII regions using spectra from the Large Sky Area Multi- Object Fiber Spectroscopic Telescope (LAMOST) survey, cross-matched with an HII…
Spectral classification and composites of galaxies in LAMOST DR4
Li-Li Wang, A-Li Luo, Shi-Yin Shen +10
We study the classification and composite spectra of galaxy in the fourth data release (DR4) of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST). We select 40…
An Efficient Method for Rare Spectra Retrieval in Astronomical Databases
Changde Du, Ali Luo, Haifeng Yang +2
One of important aims of astronomical data mining is to systematically search for specific rare objects in a massive spectral dataset, given a small fraction of identified samples…
A Sample of E+A Galaxy Candidates in LAMOST Data Released 2
Haifeng Yang, Ali Luo, Xiaoyan Chen +14
A sample of 70 E+A galaxies are selected from 37, 206 galaxies in the second data release (DR2) of Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) according to t…
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…
A Search for Spectral Galaxy Pairs of Overlapping Galaxies based on Fuzzy Recognition
Haifeng Yang, Ali Luo, Xiaoyan Chen +7
The Spectral Galaxy Pairs (SGPs) are defined as the composite galaxy spectra which contain two independent redshift systems. These spectra are useful for studying dust properties o…
