EuclidConsortiumObjectives Euclid space mission

• Understand the origin of the Universe’s accelerating

expansion

• Use weak gravitational lensing and galaxy clustering

probes to investigate the properties and the nature of

– dark energy,

– dark matter,

– gravity

Track their observational signatures on the

– geometry of the universe and

– cosmic history of structure formation

EuclidConsortiumStrength of the Euclid machine

Euclid Meeting Bologna, Sept. 7, 2011

A space mission:

• Deep NIR photometry (unfeasible from the ground)

• Superb and very table image quality (only feasible in space)

• Stable data: homogeneous data set (unfeasible from the

ground)

Stability: Systematics are small, understood and

controlled

Homogeneity : Selection function perfectly controlled

Deep NIR data for galaxies:

• Photo-z very well measured in the whole range

0.2<z<2.0 (tomography, intrinsic alignement)

• Unique Legacy value

EuclidConsortiumThe Euclid mission

Euclid Meeting Bologna, Sept. 7, 2011

• An M-class mission with constraints:

– Launcher : soyouz

– Maximum duration:7 years

• A Telescope

• 2 channels (Vis, NIR), 3 instruments (VIS, (NIS+NIP)=NISP)

• A mission: Euclid in L2, 2 surveys: Euclid Wide and Deep

• A (very important) ground segment

• An important external visible data set

• A strong core science and science team

• A collaboration between industry, ESA and the « Euclid

Mission Consortium
