PRIMA: PRIMAger, a Hyperspectral and Polarimetric Instrument

The PRobe far-Infrared Mission for Astrophysics (PRIMA) is a cryogenically-cooled, infrared observatory for the community for the next decade. PRIMAger will provide to the observers a coverage of mid-infrared to far-infrared wavelengths from about 25 to 260 micrometer. Imaging can be obtained with 12 medium-band filters (R ~ 10) covering the wavelength ranges from 25 to 80 micrometer, and 4 broad-band filters (R = 4) with polarimetric capabilities, covering the wavelength ranges from 80 to 260 micrometer.

PRIMAger’s science will allow to study the evolution of small dust grains over a wide range of redshift, assess the effect of the magnetic field in various environments, and open a vast discovery space with its versatile imaging capability.

PRIMAger is presently studied through a collaboration between the Laboratoire d’Astrophysique de Marseille (LAM) with the Centre National d’Etudes Spatiales (CNES), the Department d’Astrophysique of CEA/IRFU, the Netherlands Institute for Space Reseach (SRON) European, and the Jet Propulsion Laboratory (JPL).
