Symposium S10
29 - 30 June 2020
Gaia: The (two) billion star galaxy census: The promise of (E)DR3 and ground-based synergies
Aims and scope
The first ESA Gaia Billion Star Census of the Milky Way, was released in April 2018 as the Gaia Data Release 2 (Gaia DR2). This release contained full five parameter astrometry for ~1.3 billion sources, along with a wealth of associated data (such as magnitudes, colours, mean radial velocities for brighter objects - see https://www.cosmos.esa.int/web/gaia/data-release-2 for details). This marked a major milestone in the Gaia mission, following on from the Gaia Data Release 1 (Gaia DR1) in September 2016. Gaia is revolutionizing our understanding of the formation history of the Milky Way, and is having a significant impact on many other areas of astronomy ranging from solar system science to quasars. The impact of Gaia is set to increase through the impact of existing and planned large spectroscopic surveys.
The key goals of this symposium will be for the Gaia/GREAT community (and especially early stage researchers) to present and discuss their science highlights resulting from the two current releases of Gaia data and in anticipation of the Gaia DR3. In addition a discussion of the synergies with spectroscopic surveys such as RAVE, LAMOST, GALAH, APOGEE, Gaia-ESO will be discussed both through presentations of science highlights and discussions of new opportunities (4MOST, WEAVE, MOONS, SDSS-V). Finally, this symposium will allow the Gaia project to update the science community with the latest scientific and technical performance of Gaia, looking ahead to the release of Gaia (E)DR3.
In addition a lunchtime session will be organized to discuss future space astrometry and photometric/spectroscopic survey options.
GREAT (an initiative of the ESA Gaia Project, Gaia Science Team and Data Processing and Analysis Consortium (DPAC) Executive) is a pan-European research network involving over 1000 researchers in 20+ countries with a common interest in maximising the science potential of Gaia (http://www.great-esf.eu). GREAT, in the form of the MW-Gaia COST Action (https://www.cost.eu/actions/CA18104) is currently financially supporting networking activities across Europe.
GREAT plenary meetings have run since 2009, allowing members of the GREAT and
wider community to participate in a dynamic fashion. They are structured
around Gaia updates, presentations from related organisations (e.g. ESO),
reports from new initiatives, and new science results from the network
activities.
This will be the 13th GREAT plenary (which since 2012 have been organised within the high impact EAS EWASS).
