Identifying Galactic Substructures in 5D Space Using All-sky RR Lyrae Stars in Gaia DR3

Identifying Galactic Substructures in 5D Space Using All-sky RR Lyrae Stars in Gaia DR3

Motivated by the vast gap between photometric and spectroscopic data volumes, there is great potential in using 5D kinematic information to identify and study substructures of the Milky Way. We identify substructures in the Galactic halo using 46,575 RR Lyrae stars (RRLs) from Gaia Data Release 3, w...
