\v{Z}eljko Ivezi\'c, Steven M. Kahn, Patricia Eliason
TL;DR
This paper explores how Gaia and LSST surveys complement each other in studying the Milky Way, with LSST extending Gaia's measurements to fainter stars and enhancing data analysis capabilities.
Contribution
It highlights the synergy between Gaia and LSST, emphasizing how LSST's deeper observations complement Gaia's data and discussing opportunities for international collaboration.
Findings
LSST extends Gaia's measurements to five magnitudes fainter.
Gaia and LSST provide similar uncertainties at Gaia's faint end.
The paper details how users can participate in LSST data analysis.
Abstract
We discuss the synergy of Gaia and the Large Synoptic Survey Telescope (LSST) in the context of Milky Way studies. LSST can be thought of as Gaia's deep complement because the two surveys will deliver trigonometric parallax, proper-motion, and photometric measurements with similar uncertainties at Gaia's faint end at , and LSST will extend these measurements to a limit about five magnitudes fainter. We also point out that users of Gaia data will have developed data analysis skills required to benefit from LSST data, and provide detailed information about how international participants can join LSST.
