NIRSpec Multi-Object Spectroscopy of Distant Galaxies Pierre Ferruit (ESA) The study of the formation and evolution of galaxies is at the core of the JWST NIRSpec Guaranteed Time Observer (GTO) program. More than 80% of the NIRSpec GTO time allocation is allocated to a spectroscopic survey mixing multiobject and integral-field spectroscopy (MOS and IFS) and focusing on the physics of galaxy assembly. In this talk, I will focus on the deep and medium parts of the MOS survey that are conducted in collaboration with the NIRCam GTO team. I will describe their scientific goals, main characteristics and how they were constructed, trying to highlight the key elements of the preparation of a NIRSpec MOS proposal. The Near-Infrared Spectrograph (NIRSpec) is one of the four instruments on the James Webb Space Telescope (JWST), scheduled for launch in 2018. NIRSpec has been designed and built by the European Space Agency (ESA) with Airbus Defence and Space Germany as prime contractor and contributions from NASA. The instrument covers the wavelength range from 0.6 to 5.3 micron and features a multi-object spectroscopy (MOS) mode, an integral field unit (IFU) and a suite of slits for high contrast spectroscopy of individual objects. In this talk, I will give an overview of NIRSpec capabilities and performances with a strong focus on information useful for future observers.
