VIRAC2: NIR Astrometry and Time Series Photometry for 500M+ Stars from the VVV and VVVX Surveys
Leigh C. Smith, Philip W. Lucas, Sergey E. Koposov +11
We present VIRAC2, a catalogue of positions, proper motions, parallaxes and , , , , and near-infrared photometric time series of 545 346 537 unique stars. The cat…
Models of Distorted and Evolving Dark Matter Halos
J. L. Sanders, E. J. Lilley, E. Vasiliev +2
We investigate the ability of basis function expansions to reproduce the evolution of a Milky Way-like dark matter halo, extracted from a cosmological zoom-in simulation. For each…
The Early Merger that Made the Galaxy's Stellar Halo
N. W. Evans
The last two years have seen widespread acceptance of the idea that the Milky Way halo was largely created in an early (8-10 Gyr ago) and massive () merger. The…
A hypervelocity star with a Magellanic origin
Denis Erkal, Douglas Boubert, Alessia Gualandris +2
Using proper motion measurements from Gaia DR2, we probe the origin of 26 previously known hypervelocity stars (HVSs) around the Milky Way. We find that a significant fraction of t…
