Beside the primary science of Euclid, the wide survey covering 15,000 deg2 down to ABVIS=24.5 and ABYJH=24.0 will provide several billion galaxies and therefore additional cosmology probes for free, complementing weak lensing and galaxy clustering. Likewise, the Deep fields covering 40 deg2 down to ABVIS=26.5 and ABYJH=26.0 will provide several million sources that will be most unique samples for extragalactic and stellar astronomy.
Both wide and deep surveys will be gold mines of targets for ALMA, JWST,E-ELT and TMT and will trigger synergy science with LSST, GAIA, e-ROSITA or SKA.
The Euclid Consortium set several Science Working Groups that focus on the following “Legacy” or “Additional” science projects:
- Clusters of galaxies
- CMB Euclid galaxy survey cross-correlations
- Strong lensing statistics
- Galaxy-galaxy lensing
- Cool brown dwarfs
- Large streams and merger history of galaxies
- Study of resolved stellar populations in the Galaxy and the universe nearby
- Galaxy evolution: galaxies, AGNs, highly magnified high redshift galaxies, study of the primeval universe
- High-z Lyman Break Galaxies
- Supernovae and transients
Examples of expected number of targets Euclid may find are listed in the table below.
