Magnetic fields influence many processes in the ISM strongly. In the primordial ISM they are usually not considered, as they are assumed not to be dynamically important yet. In the presence of turbulence, however, the small-scale dynamo can amplify weak seed fields by randomly stretching, twisting and folding the field lines. The details of this process depend on the nature of turbulence, i.e....

We present first wide-field deep near-infrared imaging polarimetry (15'x60') of the Orion A Integral Shape Filament obtained with SIRPOL, simultaneous JHKs imaging polarimeter on the IRSF telescope. Most derived magnetic field orientations from aperture polarimetry are perpendicular to the elongation of the ISF. The extended H-band polarization pattern confirms the hourglass shaped structure...
