A More Complex Than Expected Formation History of the Milky Way's Last Major Merger
Hai-Feng Wang, Guan-Yu Wang, Giovanni Carraro +3
The GaiaSausageEnceladus (GSE) structure, widely recognized as the most recent major accretion event experienced by our Galaxy, is traditionally interpreted as the remnant of…
The Average Age Map of the Galactic Bulge
Jialu Nie, Martín López-Corredoira, Chao Liu +2
The Galactic Bulge, as the center of the Galaxy, is the closest laboratory for studying galaxy formation and evolution. However, its study faces significant challenges due to heavy…
Towards Understanding the Milky Way's Matter Field and Dynamical Accretion History based on AI-GS3 Hunter
Hai-Feng Wang, Guan-Yu Wang, Giovanni Carraro +5
We present GS3 Hunter (Galactic-Seismology Substructures and Streams Hunter), a novel deep-learning method that combines Siamese Neural Networks and K-means clustering to identify…
Towards Unveiling the Origins of the Milky Way Bulge through Multi-band-Messenger Sky Surveys
Hai-Feng Wang, Xiao Han, Giovanni Carraro +3
We analyze the structure and chemo-dynamical properties of the Galactic bulge using ab-type RR Lyrae stars (RRabs) from OGLE-IV and giant stars from APOGEE and Gaia. Orbital integr…
The Structure, Populations and Kinematics of the Milky Way central and inner Bulge with OGLE, APOGEE and Gaia data
Xiao Han, Hai-Feng Wang, Giovanni Carraro +4
We present an analysis of the structure, kinematics, and chemo-dynamical properties of the Milky Way bulge using RR Lyrae stars from OGLE, and giant stars from APOGEE and Gaia that…
The Wide-field Spectroscopic Telescope (WST) Science White Paper
Vincenzo Mainieri, Richard I. Anderson, Jarle Brinchmann +214
The Wide-field Spectroscopic Telescope (WST) is proposed as a new facility dedicated to the efficient delivery of spectroscopic surveys. This white paper summarises the initial con…
Galactic-Seismology Substructures and Streams Hunter with LAMOST and Gaia. I. Methodology and Local Halo Results
Guan-Yu Wang, Hai-Feng Wang, Yang-Ping Luo +4
We present a novel, deep-learning based method -- dubbed Galactic-Seismology Substructures and Streams Hunter, or GS Hunter for short, to search for substructures and streams…
Age Determination of LAMOST Red Giant Branch stars based on the Gradient Boosting Decision Tree method
Hai-Feng Wang, Giovanni Carraro, Xin Li +5
In this study we estimate the stellar ages of LAMOST DR8 Red Giant Branch (RGB) stars based on the Gradient Boosting Decision Tree algorithm (GBDT). We used 2,643 RGB stars extract…
Asymmetric Drift Map of the Milky Way disk Populations between 816 kpc with LAMOST and Gaia datasets
Xin Li, Peng Yang, Hai-Feng Wang +4
The application of asymmetric drift (AD) tomography across different populations provides valuable insights into the kinematics, dynamics, and rotation curves of the Galactic disk.…
