Properties of Galactic cirrus clouds observed by BOOMERanG

Understand

The physical properties of galactic cirrus emission are not well characterized.

• BOOMERanG is a balloon-borne experiment designed to study the cosmic microwave background at high angular resolution in the millimeter range.
• The BOOMERanG 245 and 345GHz channels are sensitive to interstellar signals, in a spectral range intermediate between FIR and microwave frequencies.
• We look for physical characteristics of cirrus structures in a region at high galactic latitudes (b~-40{\deg}) where BOOMERanG performed its deepest integration, combining the BOOMERanG data with other available datasets at different wavelengths.
