ABSTRACT A key event in the history of the Milky Way is the formation of the bar. This event
affects the subsequent structural and dynamical evolution of the entire Galaxy. When the bar …

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 …

We present a new volume-limited sample of L0–T8 dwarfs out to 25 pc defined entirely by
parallaxes, using our recent measurements from UKIRT/WFCAM along with Gaia DR2 and …

Using Gaia DR2 data, we present an up-to-date sample of white dwarfs within 20 pc of the
Sun. In total we identified 139 systems in Gaia DR2, nine of which are new detections, with …

Abstract We present∼ 120,000 Spitzer/IRAC candidate young stellar objects (YSOs) based
on surveys of the Galactic midplane between ℓ∼ 255 and 110, including the GLIMPSE I, II …

We compare distance resolved, absolute proper motions in the Milky Way bar/bulge region
to a grid of made-to-measure dynamical models with well-defined pattern speeds. The data …

We present the most precise constraints to date for the mass and age distributions of single
ultracool dwarfs in the solar neighborhood, based on an updated volume-limited sample of …

The properties of the Milky Way's nuclear stellar disc give crucial information on the epoch of
bar formation. Mira variables are promising bright candidates to study the nuclear stellar …

We have derived absolute proper motions of the entire Galactic bulge region from VVV
Infrared Astrometric Catalogue (VIRAC) and Gaia. We present these both as integrated on …

Context. The ESO public survey VISTA Variables in the Vía Láctea (VVV) surveyed the inner
Galactic bulge and the adjacent southern Galactic disk from 2009–2015. Upon its …
