AG meeting 2017
Splinter Meeting Euclid
The Euclid space mission
Time: Wednesday September 20, 14:00-16:30 and 17:00-19:00
Organizers: Tim Schrabback, Knud Jahnke
Euclid is an ESA medium class astronomy and astrophysics space mission with a planned launch in 2020. Using a 1.2m telescope Euclid will survey 15000 square degrees of the extragalactic sky in its Wide Survey, simultaneously obtaining optical imaging with 0.2" resolution (>24.5 AB mag in the broad VIS filter at 10 sigma) and NIR slitless spectroscopy, as well as NIR photometry (24.0 AB mag in YJH at 5 sigma). Observations that are deeper by ~2mag will be obtained in the 40 square degree Euclid Deep Survey.
Measuring galaxy shapes for weak gravitational lensing as well as galaxy redshifts, Euclid will probe the evolution of cosmic structures and the distance-redshift relationship, yielding unprecedented constraints on cosmological parameters, in particular regarding the nature of dark energy. Additionally, the Euclid data will provide a tremendous legacy for studies ranging from the identification of brown dwarfs and nearby dwarf galaxies via the evolution of galaxies and galaxy clusters to the search for QSOs at redshifts z>8.
The Euclid Consortium consists of about 1400 researchers and engineers from 14 European countries, the USA, and Canada. It is responsible for the building and operation of the scientific instruments for Euclid, the pipeline development, and the scientific analysis of the Euclid data and complementary observations, e.g. ground-based survey data for photometric redshift estimation.
Germany provides major contributions within the Euclid Consortium, especially regarding the building of the NIR instrument NISP, the analysis of complementary ground-based survey data and the catalogue generation, the weak gravitational lensing measurements, and several Euclid Science Working groups, including e.g. theory and galaxy clusters.
It is the goal of this splinter to provide an overview of the Euclid Mission and the preparatory work conducted within Germany to the broader community. This is timely not only because of the approaching launch, but also given that the yearly Euclid Mission Conference will be held in Germany in 2018 (June 11-15, Bonn-Bad Godesberg). This splinter will be open to both current members and non-members of the Euclid Consortium (note that applications for membership can still be submitted as explained at https://www.euclid-ec.org/?page_id=1101). In addition to broader overview presentations we encourage the submission of abstracts for more focused contributed talks.
