Abstract: Gaia recently revealed a two-armed spiral pattern in the vertical phase-space distribution of the inner Galactic disk (guiding radius Rg ∼ 6.2 kpc), indicating that some non-adiabatic perturbation symmetric about the mid-plane is driving the inner… read more here.

Abstract: While the number of stars in the Galactic bulge with detailed chemical abundance measurements is increasing rapidly, the inner Galactic bulge (|b| +0.6 dex. The Galactic Centre field reveals in contrast a mainly metal-rich population… read more here.
