From BRAVA to BAaDE: A New Kinematic Survey of the Bulge AGB
  We consider interesting results on the kinematics of the bulge, beginning
with Mould's (1983) measurement of the velocity dispersion of the late M giants
in the bulge, and carrying the discussion on to the present day, to discuss the
largest survey ever undertaken of luminous SiO maser AGB stars. This SiO maser
population of AGB stars is too luminous to have evolved from the oldest
globular cluster age stellar population, yet has a velocity dispersion
consistent with the oldest populations (the red clump stars) in the bulge. We
identify two groups of maser stars by their kinematics; the subgroup with
kinematics similar to the bulge has the highest bolometric luminosities with
some giants reaching $M_{bol}<-6$. In a new result, we find that the most
luminous maser stars with bulge kinematics are concentrated to the Galactic
plane with the most luminous maers being found at $b<\mid 1.5^\circ \mid$;
while the disk maser population shows no such difference. This mirrors a
similar concentration to the Galactic Center found for long period Miras, noted
in earlier studies. We conclude that the maser population represents another
facet of the growing tension between evidence supporting a bulge population
dominated by old stars, and a significant fraction of intermediate age stars.
