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…
The total stellar halo mass of the Milky Way
Alis J. Deason, Vasily Belokurov, Jason L. Sanders
We measure the total stellar halo luminosity using red giant branch (RGB) stars selected from Gaia data release 2. Using slices in magnitude, colour and location on the sky, we dec…
The Inside-out Growth of the Galactic Disk
Neige Frankel, Jason Sanders, Hans-Walter Rix +2
We quantify the inside-out growth of the Milky Way's low-alpha stellar disk, modelling the ages, metallicities and Galactocentric radii of APOGEE red clump stars with 6 < R < 13 kp…
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…
Transverse kinematics of the Galactic bar-bulge from VVV and Gaia
Jason L. Sanders, Leigh Smith, N. Wyn Evans +1
We analyse the kinematics of the Galactic bar-bulge using proper motions from the ESO public survey Vista Variables in the Via Lactea (VVV) and the second Gaia data release. Gaia h…
The pattern speed of the Milky Way bar from transverse velocities
Jason L. Sanders, Leigh Smith, N. Wyn Evans
We use the continuity equation to derive a method for measuring the pattern speed of the Milky Way's bar/bulge from proper motion data. The method has minimal assumptions but requi…
Lessons from the curious case of the `fastest' star in Gaia DR2
Douglas Boubert, Jay Strader, David Aguado +6
Gaia DR2 5932173855446728064 was recently proposed to be unbound from the Milky Way based on the median radial velocity given in Gaia D…
