4.4 Mid/Far-IR

The Mid-Infrared Instrument (MIRI)

The Mid-Infrared Instrument (MIRI) on JWST will provide direct imaging and medium resolution spectroscopy (R~3000) over the wavelength range 5-28.3 micron. Coronagraphic imaging at 10.65, 11.4, 15.5 and 23 micron, and low resolution spectroscopy (R~100) over the wavelength range 5-10 micron. "MIRI" is expected to make significant contributions to all four of the primary science themes for JWST:

  1. Discovery of the "first light".
  2. Assembly of galaxies: history of star formation, growth of black holes, production of heavy elements.
  3. How stars and planetary systems form,
  4. Evolution of planetary systems and conditions for life.

MIRI will use the Lyman break technique to identify objects at increasing redshifts up to z = 30 or higher. More detailed follow-ups are being planned for the brightest first light source candidates by MIRI.

MIRI will use near-infrared spectroscopy at R = 100 will be needed to verify the photometric redshifts and will observe spectroscopic follow up at R = 1000 aimed at measuring the Balmer line intensities will provide star formation rates and estimates of the dust content. It's being planned to obtain high signal-to-noise, R = 1000, near-infrared spectra of QSOs or bright galaxies identified in other surveys.

MIRI Science-Requirements

What can be done with DAG
  • The DAG can study detect bright far objects or QSOs in a dedicated deep or ultra-deep survey and this can be provide a basis for MIRI.
  • The DAG telescope can make spectroscopic follow-up observations in greater resolutions, if DAG has a high-resolution spectroscopic instrument in near-infrared.
