Gaia-CU9

Lead Research Organisation: University of Bristol
Department Name: Physics

Abstract

Gaia is the cornerstone ESA mission which will provide the first astrometric census of the sky. One billion sources will be surveyed; allowing major advances in Galactic structure and evolution, stellar evolution, solar system dynamics, exo-planetary systems, cosmology and fundamental physics. Gaia is scheduled for launch in autumn 2013. Its huge data set will revolutionise much of astrophysics, provided astronomers can access and understand the data. This proposal is to support the UK leadership roles in Gaia data delivery to users, especially in archive design, science requirements specification, documentation, and support for public-access interface software.

Collaboration G (2017) Gaia Data Release 1. Testing parallaxes with local Cepheids and RR Lyrae stars in Astronomy and Astrophysics

 
Description The software tools developed are the principal means by which astronomers (and the public, in future) access the Gaia database, and so can examine the positions and motions of stars in the Galaxy. The plotting and remote data access methods are generic, and widely applicable.
Exploitation Route The data access and plotting methods are widely applicable for any users with distributed datasets which need combining and/or comparing.
Sectors Aerospace, Defence and Marine,Electronics,Financial Services, and Management Consultancy

 
Description The software developed under this grant provides user interface to the Gaia dataset, and the results from the first extractions from that dataset, performed usually with these tools, have been the subject of extensive press releases about the distribution of stars in the Galaxy.
