MOSAIC: A Multi-Object Spectrograph for the E-ELT

The development of the European Extremely Large Telescope (E-ELT) with a 39m-size primary mirror is the major priority for the European ground-based astronomical infrastructure in the coming years. AIP is a partner in the development of an E-ELT Multi-Object Spectrograph (MOSAIC), which has been selected for a phase-A study by the European Southern Observatory (ESO).

MOSAIC combines both imaging and multi-object spectroscopy to enable the observation of a large number of extended objects. The science cases range from the most distant galaxies, galaxy clusters and assembly, resolved stellar populations to planetary formation studies.

Given AIP's experience and interest, we participate in the work-package called "Science Optical Signal Transport (SOST)", which essentially encompasses the fibre-link between telescope focal plane to the VIS and NIR spectrograph systems. A further area of engagement is with respect to the Data Reduction Software for this instrument, based on AIP's expertise with MUSE. The MOSAIC concept is proposed by a European-wide consortium, led by the Observatoire de Paris (GEPI). The phase-A studies commences in spring 2016, with a foreseen duration of two years. AIP's contributions are supported by a grant from the BMBF-Verbundforschung,
