ARGOS II: The Galactic Bulge Survey
K. Freeman, M. Ness, E. Wylie de Boer +8
We describe the motivation, field locations and stellar selection for the ARGOS spectroscopic survey of 28,000 stars in the bulge and inner disk of the Milky Way galaxy across lati…
ARGOS III: Stellar Populations in the Galactic Bulge of the Milky Way
M. Ness, K. Freeman, E. Athanassoula +7
We present the metallicity results from the ARGOS spectroscopic survey of the Galactic bulge. Our aim is to understand the formation of the Galactic bulge: did it form via mergers,…
Manifold-driven spirals in N-body barred galaxy simulations
E. Athanassoula
We discuss the properties of spiral arms in a N-body simulation of a barred galaxy and present evidence that these are manifold-driven. The strongest evidence comes from following…
The origin of the split red clump in the Galactic bulge of the Milky Way
M. Ness, K. Freeman, E. Athanassoula +8
Near the minor axis of the Galactic bulge, at latitudes b < -5 degrees, the red giant clump stars are split into two components along the line of sight. We investigate this split u…
