A clustering-based search for substructures in the Galactic plane and bulge using RR Lyrae stars as tracers
N. Cristi-Cambiaso, C. Navarrete, M. Catelan +2
Although many globular clusters (GCs) have been identified in the Galaxy, their population is estimated to be incomplete, especially in regions with strong crowding and interstella…
New kinematic map of the Milky Way bulge
Carlos Quezada, Manuela Zoccali, Elena Valenti +7
The kinematics of the Milky Way bulge is known to be complex, reflecting the presence of multiple stellar components with distinct chemical and spatial properties. In particular, t…
VVV catalog of ab-type RR Lyrae in the inner Galactic bulge
M. Zoccali, C. Quezada, R. Contreras Ramos +7
Context. Observational evidence has accumulated in the past years, showing that the Galactic bulge includes two populations, a metal poor and a metal rich one that, in addition to…
Comparing bulge RR Lyrae stars with bulge giants -- Insight from 3D kinematics
J. Olivares Carvajal, M. Zoccali, M. De Leo +6
The structure and kinematics of the old component of the Galactic bulge are still a matter of debate. The bulk of the bulge as traced by red clump stars includes two main component…
