The Anisotropy in Interstellar Media

Hua-bai Li


Very recent observations have begun to reveal that density fragmentation and turbulent velocity in ISM may be highly filamentary. At the same time, Galactic B-fields have been found to be strong enough to imprint their orientations in many molecular clouds. These kinds of observations can place crucial constraints on competing ISM scenarios, because not all of them predict the observed anisotropy. We have developed novel methods to probes the relations of B fields and ISM anisotropy.
