Other science

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
  • Exo-planets

Examples of expected number of targets Euclid may find are listed in the table below.
