Models of Bars with Exponential Density Profiles
D. P. McGough, N. W. Evans, J. L. Sanders
We present a new model for galactic bars with exponentially falling major axis luminosity profiles and Gaussian cross-sections. This is based on the linear superposition of Gaussia…
Age Demographics of the Milky Way Disk and Bulge
J. Grady, V. Belokurov, N. W. Evans
We use the extensive Data Release 2 set of Long Period Variables to select a sample of Oxygen-rich Miras throughout the Milky Way disk and bulge for study. Exploiting the re…
Dynamical Relics of the Ancient Galactic Halo
Zhen Yuan, G. C. Myeong, Timothy C. Beers +11
We search for dynamical substructures in the LAMOST DR3 very metal-poor (VMP) star catalog. After cross-matching with Gaia DR2, there are 3300 VMP stars with available high-quality…
Spectroscopy of the Young Stellar Association Price-Whelan 1: Origin in the Magellanic Leading Arm and Constraints on the Milky Way Hot Halo
David L. Nidever, Adrian M. Price-Whelan, Yumi Choi +7
We report spectroscopic measurements of stars in the recently discovered young stellar association Price-Whelan 1 (PW 1), which was found in the vicinity of the Leading Arm (LA) of…
The Biggest Splash
Vasily Belokurov, Jason L. Sanders, Azadeh Fattahi +4
Using a large sample of bright nearby stars with accurate Gaia Data Release 2 astrometry and auxiliary spectroscopy we map out the properties of the principle Galactic components s…
Dark Shards: velocity substructure from Gaia and direct searches for dark matter
Ciaran A. J. O'Hare, N. Wyn Evans, Christopher McCabe +2
Data from the Gaia satellite show that the solar neighbourhood of the Milky Way's stellar halo is imprinted with substructure from several accretion events. Evidence of these event…
