PhotoRedshift-MML: a multimodal machine learning method for estimating photometric redshifts of quasars
Shuxin Hong, Zhiqiang Zou, A-Li Luo +3
We propose a Multimodal Machine Learning method for estimating the Photometric Redshifts of quasars (PhotoRedshift-MML for short), which has long been the subject of many investiga…
Estimating Atmospheric Parameters from LAMOST Low-Resolution Spectra with Low SNR
Xiangru Li, Si Zeng, Zhu Wang +3
Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) acquired tens of millions of low-resolution stellar spectra. The large amount of the spectra result in the urgenc…
Ultracool dwarfs identified using spectra in LAMOST DR7
You-Fen Wang, A-Li Luo, Wen-Ping Chen +7
In this work, we identify 734 ultracool dwarfs with a spectral type of M6 or later, including one L0. Of this sample, 625 were studied spectroscopically for the first time. All of…
Strong [OIII]λ5007 emission line compact galaxies in LAMOST DR9: Blueberries, Green Peas and Purple Grapes
Siqi Liu, A-Li Luo, Huan Yang +8
Green Pea and Blueberry galaxies are well-known for their compact size, low mass, strong emission lines and analogs to high-z Lyα emitting galaxies. In this study, 1547 strong [OII…
Identification of White Dwarf from Gaia EDR3 via Spectra from LAMOST DR7
Xiao Kong, A-Li Luo
We cross-matched 1.3 million white dwarf (WD) candidates from Gaia EDR3 with spectral data from LAMOST DR7 within 3 arcsec. Applying machine learning described in our previous work…
A new moving group in the Local Arm
Xilong Liang, Jingkun Zhao, Yuqin Chen +5
We present a new moving group clustered in kinematics, spatial position and elemental abundances. Its spatial position is around the center of the Local Arm of the Milky Way. A con…
