TL;DR: In this article, the authors combined the precise parallaxes and optical photometry delivered by Gaia's second data release with the photometric catalogues of Pan-STARRS1, 2MASS, and AllWISE, and derived Bayesian stellar parameters, distances, and extinctions for 265 million of the 285 million objects brighter than G ǫ = 18.

TL;DR: In this article, a semi-empirical, largely model-independent approach for estimating Galactic birth radii, r_birth, for Milky Way disk stars is presented, which relies on the justifiable assumption that a negative radial metallicity gradient in the interstellar medium (ISM) existed for most of the disk lifetime.

TL;DR: In this paper, the authors measured the escape speed curve of the Milky Way based on the analysis of the velocity distribution of counter-rotating halo stars from the Gaia DR2.

TL;DR: In this paper, the authors combine the precise parallaxes and optical photometry delivered by Gaia's second data release (Gaia DR2) with the photometric catalogues of PanSTARRS-1, 2MASS, and AllWISE, and derive Bayesian stellar parameters, distances, and extinctions for 265 million stars brighter than G=18.
