The Science Case against which we evaluate the project resides on three pillars:

- contemporary science cases (DRM, instrument teams, DRSP, ...)

- synergy with other facilities (8m-class telescopes, interferometry, ALMA, JWST, LSST/surveys, SKA, ...)

- discovery potential (open unique parameter space, be prepared for the unexpected, ...)

Synergy with Large Facilities


The main synergy is expected with:

•The 8-10m class Telescopes (VLT/I, ...)•The JWST•ALMA•LSST•SKA / SKA Pathfinders•...


JWST key science

•The End of the Dark Ages: First Light and Reionization •Assembly of Galaxies➱ optical/NIR sensitive multi-object spectrographs

The Birth of Stars and Protoplanetary SystemsPlanetary Systems and the Origins of Life

➱mid-IR instrument (high spatial/spectral resolution at 3-15 μm)➱ planet-finder (incl. low-resolution spectroscopy and polarimetry)


ALMA key science

•Detect spectral line emission from CO or CII in a normal galaxy like the Milky Way at a redshift of z = 3, in less than 24 hours of observation. ➱ NIR sensitive integral spectrograph and imager

•Image the gas kinematics in protostars and in protoplanetary disks around young Sun-like stars at a distance of the nearest star-forming clouds.➱ NIR and mid-IR high-spectral resolution instruments

•Provide precise images at an angular resolution of 0.1 arcsec.


The Unknown


Enabling discovery is achieved by opening parameter space (see Martin Harwit: “Cosmic Discovery”)

The E-ELT excels - in collecting power and - in spatial resolution.

These should not be compromised and pushed into a range unattained previously.
