BLAST-Pol: The Balloon-borne Large Aperture Sub-millimeter Telescope for Polarimetry
The BLAST-Pol collaboration
The Balloon-borne Large Aperture Sub-millimeter Telescope for Polarimetry (BLAST-Pol) is a 1.8 meter stratospheric telescope designed to study the role played by magnetic fields in the star formation process. BLAST-Pol images the sky onto a focal plane that consist of 270 feed-horn coupled bolometric detectors at 250, 350 and 500 microns with a diffraction limited resolution of 30" at the shorts wavelength, sufficient to trace fields into cloud cores and dense filaments in nearby giant molecular clouds in the Milky Way. BLAST-Pol successfully observed 8 molecular clouds in a 9.5 day flight over Antarctica.
I will present instrument characteristics and the importance of the data set collected for the study of polarized dust emission in Galactic star-forming regions.
