The Metallicity Distribution of the Milky Way Bulge
M. Ness, K. Freeman
The Galactic bulge of the Milky Way is made up of stars with a broad range of metallicity, -3.0 < [Fe/H] < 1 dex. The mean of the Metallicity Distribution Function (MDF) decreases…
The Influence of a Kinematically Cold Young Component on Disc-Halo Decompositions in Spiral Galaxies: Insights from Solar Neighbourhood K-giants
S. Aniyan, K. C. Freeman, O. E. Gerhard +2
In decomposing the HI rotation curves of disc galaxies, it is necessary to break a degeneracy between the gravitational fields of the disc and the dark halo by estimating the disc…
Identification of Globular Cluster Stars in RAVE data I: Application to Stellar Parameter Calibration
B. Anguiano, D. B. Zucker, R. -D. Scholz +22
We present the identification of potential members of nearby Galactic globular clusters using radial velocities from the RAdial Velocity Experiment Data Release 4 (RAVE-DR4) survey…
The Parent Populations of 6 groups identified from Chemical Tagging in the Solar neighborhood
Alice C. Quillen, Borja Anguiano, Gayandhi De Silva +4
We estimate the size and distribution of the parent populations for the 6 largest (at least 20 stars in the Solar neighborhood) chemical groups identified in the Chemical Tagging e…
The GALAH Survey: Scientific Motivation
G. M. De Silva, K. C. Freeman, J. Bland-Hawthorn +44
The GALAH survey is a large high-resolution spectroscopic survey using the newly commissioned HERMES spectrograph on the Anglo-Australian Telescope. The HERMES spectrograph provide…
