The mission will investigate the distance-redshift relationship and the evolution of cosmic structures. It achieves this by measuring shapes and redshifts of galaxies and clusters of galaxies out to redshifts ~2, or equivalently to a lookback time of 10 billion years. It will therefore cover the entire period over which dark energy played a significant role in accelerating the expansion. The Near IR Spectrometer Photometer (NISP) role is to measure the galaxies' redshift. The baseline for NISP is an Infrared instrument allowing observation in slit less "spectrometry" mode thanks to several Grisms, or in "Photometry" mode using several filters. The NISP instrument is provided by the EUCLID consortium, led by the Laboratoire d'Astrophysique de Marseille (LAM).ELETTRONICOenResearch reportFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation::PE9_17 Instrumentation – telescopes, detectors and techniques
