Identifying stellar streams in Gaia DR2 with data mining techniques
TL;DR: In this paper, the integrals of motion for 31 234 stars, to a distance of 4 kpc from the Sun, were calculated using a combination of data mining, numerical, and statistical techniques.

TL;DR: In this article, the authors measured the mass of the Large Magellanic Cloud (LMC) by fitting dynamical models to five streams in the Southern Galactic hemisphere, combining observations from the Southern Stellar Stream Spectroscopic Survey ($S}^5$), Gaia EDR3, and the Dark Energy Survey (DES).

TL;DR: In this article, the authors combined spectral parameters from the GALAH survey with the Gaia DR2 catalogue to study the dynamics and chemistry of five old sparse high-latitude clusters in more detail.
