Description
Using polarimetry, at both visible and submillimeter wavelengths, we
propose to study the role and to compare the structure of the magnetic
fields within and near filamentary molecular clouds. The optical
polarization data obtained at Mont Mégantic and from the Heiles
catalog constrain the large scale topology of magnetic fields in the
near environment of the clouds. Submillimeter data probe the structure
of the field at smaller scale within the clouds. The aim of this
research is to put constraints on the way the magnetic field threading
the filaments connects to larger structures in the ISM. This should help
to illuminate the large scale topology of the field, which is crucial to
understanding the formation of filaments and the role of magnetic fields
within these structures. Two different regions have been selected for
this project, OMC where star formation actively occurs and CL04/CL21
which is a cold molecular filament in the earliest stages of stellar
formation.
