Optimized HDBSCAN clustering for reconstructing the merger history of the Milky Way: applications and limitations

Andrea Sante, Andreea S. Font, Dharmesh Mistry +2

Clustering algorithms can help reconstruct the assembly history of the Milky Way by identifying groups of stars sharing similar properties in a kinematical or chemical abundance sp…

Applying machine learning to Galactic Archaeology: how well can we recover the origin of stars in Milky Way-like galaxies?

Andrea Sante, Andreea S. Font, Sandra Ortega-Martorell +2

We present several machine learning (ML) models developed to efficiently separate stars formed in-situ in Milky Way-type galaxies from those that were formed externally and later a…
