Multi-object spectroscopy with the European ELT: scientific synergies between EAGLE and EVE

摘要

The EAGLE and EVE Phase A studies for instruments for the European Extremely Large Telescope (E-ELT) originatedfrom related top-level scientific questions, but employed different (yet complementary) methods to deliver the requiredobservations. We re-examine the motivations for a multi-object spectrograph (MOS) on the E-ELT and present a unifiedset of requirements for a versatile instrument. Such a MOS would exploit the excellent spatial resolution in the near-infrared envisaged for EAGLE, combined with aspects of the spectral coverage and large multiplex of EVE. We brieflydiscuss the top-level systems which could satisfy these requirements in a single instrument at one of the Nasmyth foci ofthe E-ELT.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
