The Proper Motion of Pyxis: the first use of Adaptive Optics in tandem with HST on a faint halo object
Tobias K. Fritz, Sean T. Linden, Paul Zivick +13
We present a proper motion measurement for the halo globular cluster Pyxis, using HST/ACS data as the first epoch, and GeMS/GSAOI Adaptive Optics data as the second, separated by a…
Detection of a dearth of stars with zero angular momentum in the solar neighbourhood
Jason A. S. Hunt, Jo Bovy, Raymond G. Carlberg
We report on the detection in the combined -DR1/RAVE data of a lack of disk stars in the solar neighbourhood with velocities close to zero angular momentum. We propose that t…
Galactic rotation in Gaia DR1
Jo Bovy
The spatial variations of the velocity field of local stars provide direct evidence of Galactic differential rotation. The local divergence, shear, and vorticity of the velocity fi…
The shape of the inner Milky Way halo from observations of the Pal 5 and GD-1 stellar streams
Jo Bovy, Anita Bahmanyar, Tobias K. Fritz +1
We constrain the shape of the Milky Way's halo by dynamical modeling of the observed phase-space tracks of the Pal 5 and GD-1 tidal streams. We find that the only information about…
The Sloan Digital Sky Survey Quasar Catalog: twelfth data release
Isabelle Pâris, Patrick Petitjean, Nicholas P. Ross +43
We present the Data Release 12 Quasar catalog (DR12Q) from the Baryon Oscillation Spectroscopic Survey (BOSS) of the SDSS-III. This catalog includes all SDSS-III/BOSS objects that…
The number and size of subhalo-induced gaps in stellar streams
Denis Erkal, Vasily Belokurov, Jo Bovy +1
Ample observational capabilities exist today to detect the small density perturbations that low-mass dark matter subhaloes impart on stellar streams from disrupting Galactic satell…
