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…
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…
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…
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…
