The Millimeter-Wave Bolometric Interferometer (MBI):




  The MBI-4 demonstrator, and a future space-based version of MBI, will be capable of performing the following scientific observations:
  • Search for primordial B-mode polarization in the cosmic microwave background (CMB).
  • Search for intracluster magnetic fields via Faraday rotation.
  • Map magnetic fields near the core of our galaxy.
With the MBI-4 demonstrator and a future spaced-based MBI we expect to achieve the following scientific goals:
  • Characterize the polarization of the CMB. MBI will measure simultaneously the temperature and polarization anisotropy of the CMB at angular scales from 30' to 40''
  • Characterize clustering in the far-infrared background (FIRB).
  • Measure and map magnetic fields near the center of the galaxy by measuring the Faraday rotation of synchrotron radiation.
  • Measure the wavelength dependent properties of dust polarization.

  Other possible science goals include the following:
  • Image the Sunyaev-Zeldovich (SZ) effect in clusters of galaxies.
  • Spectrally separate the kinetic and thermal SZ effects. Search for CMB and SZ point source foregrounds.
