We present the first results from the BAaDE ( Bulge Asymmetries and Dynamic Evolution ) survey .
Though only a subset of the complete survey ( \sim 2700 out of \sim 20000 final sources ) , our data comprise the largest radio kinematic survey to date of stellar SiO masers observed toward the Galactic bulge and plane from -15 ^ { \circ } < l < +12 ^ { \circ } and -6 ^ { \circ } < b < +6 ^ { \circ } .
Our sources include a substantial number of line-of-sight ( LoS ) velocities in high extinction regions within \pm 1 ^ { \circ } of the Galactic plane .
When matched with 2MASS The Two Micron All Sky Survey , Skrutskie et al .
( 2006 ) photometry , our radio-detected sample lies significantly brighter than and red-ward of the first red giant branch tip , reaching extremes of ( J - Ks ) _ { 0 } > 8 , colors consistent with Mira variables and mass losing AGB stars .
We see a clean division into two kinematic populations : a kinematically cold ( \sigma \sim 50 km sec ^ { -1 } ) population that we propose is in the foreground disk , consisting of giants with 2MASS Ks < 5.5 , and a kinematically hot ( \sigma \sim 100 km sec ^ { -1 } ) candidate bulge/bar population for most giants with Ks > 5.5 .
Only the kinematically hot giants with Ks > 5.5 include the reddest stars .
Adopting 8.3 kpc to the Galactic Center , and correcting for foreground extinction , we find that most of the sources have M _ { bol } \sim - 5 , consistent with their being luminous , and possibly intermediate age , AGB stars .
We note some tension between the possibly intermediate age of the kinematically hot population , and its high velocity dispersion compared to the disk .
