We investigate the kinematic-chemical distribution of red-giant branch stars from the LAMOST survey crossed matched with Gaia DR2 proper motions, and present time tagging for the well-known ridge structures (diagonal distributions for V _R in the R , V ...

Star Formation in the Milky Way and Nearby Galaxies [PDF]
We review progress over the past decade in observations of large-scale star formation, with a focus on the interface between extragalactic and Galactic studies.

Building an Acceleration Ladder with Tidal Streams and Pulsar Timing
We analyse stellar streams in action-angle coordinates combined with recent local direct acceleration measurements to provide joint constraints on the potential of our galaxy.

Trigonometric Parallaxes of High-mass Star-forming Regions: Our View of the Milky Way [PDF]
We compile and analyze approximately 200 trigonometric parallaxes and proper motions of molecular masers associated with very young high-mass stars. Most of the measurements come from the BeSSeL Survey using the VLBA and the Japanese VERA project.

Milky Way Cepheid Standards for Measuring Cosmic Distances and Application to Gaia DR2: Implications for the Hubble Constant [PDF]
We present Hubble Space Telescope (HST) photometry of a selected sample of 50 long-period, low-extinction Milky Way Cepheids measured on the same WFC3 F555W-, F814W-, and F160W-band photometric system as extragalactic Cepheids in Type Ia supernova host ...

Charlie Walker, Ben Shaw and colleagues give an overview of how the sensitivity, superb resolution and lack of obscuration in e-MERLIN data is changing what we know about our home galaxy and the lifecycles of its stars.

A Gaia DR2 view of the open cluster population in the Milky Way [PDF]
Context. Open clusters are convenient probes of the structure and history of the Galactic disk. They are also fundamental to stellar evolution studies.

Modelling the chemical evolution of the Milky Way [PDF]
In this review, I will discuss the comparison between model results and observational data for the Milky Way, the predictive power of such models as well as their limits.

The Milky Way’s plane of satellites is consistent with ΛCDM
The Milky Way is surrounded by 11 ‘classical’ satellite galaxies in a remarkable configuration: a thin plane that is possibly rotationally supported. Such a structure is thought to be highly unlikely to arise in the standard ( Λ CDM) cosmological model (
