Summary
The Near Infrared Spectrograph (NIRSpec) on board of the James Webb Space Telescope (JWST) will be equipped with an Integral Field Unit (IFU) which will allow the two-dimensional spectral characterization of astronomical objects with unprecedented depths, especially in the 2-5 micron wavelength range. In particular, NIRSpec-IFU observations of high-z galaxy populations will permit the capture of their often complex two-dimensional physical and kinematical structure, a pre-requisite for carrying out a number of studies. These types of observations will also help to understand possible observational biases of large 1D (i.e. slit) surveys to be carried out in multi-object mode. Here we describe the main characteristics of the NIRSpec-IFU, as well as its expected sensitivity and performance for observations of high-z galaxy populations.
