Euclid-France Days 2013

5-6 December 2013, at the IAP (Institut d'Astrophysique de Paris)

New players completed the team for the Euclid project in 2013, with the selection of Thales as satellite prime contractor and Astrium to build the telescope.

It was also an important year for the Consortium, with ESA reviews in the spring and autumn.

And with the go-ahead in July for France’s contribution to Euclid from CNES’s Board of Directors, the way is now clear to pursue the mission up to launch with the full support of agencies and our overseeing ministries. This is a unique privilege with respect to our Consortium partners.

This Euclid France meeting at year’s end was therefore an opportunity to review the project’s progress and underline the broad range of French science actions undertaken in readiness for the mission, both in the SWGs and the OUs.

Unlike in previous years, it was decided to spread the Euclid-France meeting over two days to leave more time for discussion and allow us to examine certain points in more depth.

This year’s Euclid France days were held at the IAS astrophysics institute in Paris, which is celebrating its 75th anniversary.
