• Our Milky Way As A Pure-Disk Galaxy-A Challenge for Galaxy Formation 

      Shen, Juntai T.; Rich, R. Michael; Kormendy, John; Howard, Christian D.; De Propris, Roberto; Kunder, Andrea (2010-09)
      Bulges are commonly believed to form in the dynamical violence of galaxy collisions and mergers. Here, we model the stellar kinematics of the Bulge Radial Velocity Assay ( BRAVA) and find no sign that the Milky Way contains ...

(2013-04)
      Despite its importance for understanding the nature of early stellar generations and for constraining Galactic bulge Formation models, at present little is known about the metal-poor stellar content of the central Milky ...
