Seminário do DF - Abstract: MOONS will be the next Multi-Object Optical and Near-infrared Spectrograph for the Very Large Telescope, able to simultaneously observe 1000 targets, feeding a bunch of optical fibres which can be placed at user-specified locations on the Nasmyth focal plane using individual robotic positioners.The sub-fields thus selected are then driven by the fibres into two identical cryogenic spectrographs mounted on the Nasmyth platform of one of the ESO VLT 8 m telescopes. Such a facility will allow a veritable host of Galactic, Extragalactic and Cosmological questions to be addressed. In this seminar we will describe the instrument and its current status of development, detailing the Portuguese contribution. Speaker: Alexandre Cabral (Instituto de Astrofísica e Ciências do Espaço e Laboratório de Óptica Lasers e Sistemas – Dep. Física, Faculdade de Ciências da Universidade de Lisboa)
