MEGARA (Multi-Espectrógrafo en GTC de Alta Resolución para Astronomía) is a facility instrument designed for the 10.4m GTC telescope in La Palma (Spain). Once installed at GTC by the end of 2016, will offer two different observing modes to the community, the Large Compact Bundle (LCB) mode, an Integral Field Unit (IFU) covering 12.5” x 11.3” on the sky with a spaxel size of 0.62” and a Multi-Object Spectroscopy (MOS) mode that will allow observing 100 objects in a region of 3.5’ x 3.5’ around the LCB IFU. Eight of these bundles will be devoted to the determination of the sky during the observation with the LCB. Each of the MEGARA MOS positioners can place a mini-bundle of 7 fibers (0.62”/fiber) with an absolute positioning requirement of 25 micron, covering an approximately circular area of 1.6" in diameter on the sky. Both the LCB IFU and MOS capabilities of MEGARA will provide intermediate-to-high spectral resolutions (R~6000, 11000 and 18700).
In this webpage you can find information on the detailed design and construction status of the MEGARA instrument for the 10.4m GTC telescope along with its scientific drivers as put together by our Science Team. MEGARA will arrive to GTC before the end of 2016 with a planned first light on April 2017.
The MEGARA consortium is responsible for the design and construction of the instrument and includes the Universidad Complutense de Madrid (UCM, Spain), the Instituto Nacional de Astrofísica, Óptica y Electrónica (INAOE, México), the Instituto de Astrofísica de Andalucía (IAA-CSIC, Spain), and the Universidad Politécnica de Madrid (UPM, Spain). Main private contractors are FRACTAL (Spain) and AVS (Spain). Other contractors include SEDI (France), Wasatch Photonics (USA), AMUS (Germany), GMV (Spain) and Hellma Materials GmbH.
The PI (Armando Gil de Paz) and the Science Group at UCM belong to GUAIX, the UCM group of Extragalactic Astrophysics and Astronomical Instrumentation, part of the "Departamento de Astrofísica y CC. de la Atmósfera".
