Revealing the structure and internal rotation of the Sagittarius dwarf spheroidal galaxy with gaia and machine learning

We present a detailed study of the internal structure and kinematics of the core of the Sagittarius dwarf spheroidal galaxy (Sgr). Using machine-learning techniques, we have combined the information provided by 3300 RR Lyrae stars, more than 2000 spectroscopically observed stars, and the Gaia second...
