Resumo

With its 39m primary mirror, the ESO Extremely Large Telescope (E-ELT) will be the largest optical/nearinfrared telescope ever built. MOSAIC (Multi-Object Spectrograph for Astrophysics, Inter-galactic medium studies and Cosmology) is expected to become the E-ELT´s workhorse instrument for astrophysics, intergalactic medium studies and cosmology in the coming decades. MOSAIC will fully explore the large aperture and superb spatial resolution of the biggest eye on the sky. Key science cases involve searching for extra-galactic planets, resolving stellar populations in thousands of nearby galaxies, and studying highredshift galaxies at the edge of the visible universe. MOSAIC is a fiber-fed spectrograph, covering the telescope´s full field of view with several hundred fibers and a dozen integral field units with adaptive optics capability delivering milli-arcsec spatial resolution, providing spectra ranging from the ultraviolet to the near infrared (380 – 2500 nm) at intermediate spectral resolution. The MOSAIC consortium includes scientists from Brazil, France, The Netherlands, and the United Kingdom, as main partners. Another 6 European countries are associated with the consortium at different levels. The Netherlands will be involved in designing and building the MOSAIC spectrographs; Brazil will contribute to its fiber system and spectrograph slit assembly. This proposal aims to study and develop the fibers to spectrograph interface by producing a prototype slit assemblies for MOSAIC, exchanging expertise between Brazilian and Dutch technicians and industry, and to scientifically explore state-of-art MOS observations to optimize the scientific and technical requirements for MOSAIC.
