Magnetic Fields towards High-Latitude Molecular Clouds

More than 100 molecular clouds detected in CO(1­0) emission are at high Galactic latitudes. We have searched the latest GALFA data cubes to find HI envelopes coincident with 6 of these molecular clouds. We propose to use 130 hours of Arecibo time in an attempt to detect Zeeman splitting of the 21-cm line in the HI envelopes around these 6 high-latitude molecular clouds. While this is a significant investment of time, detections of fields around these molecular clouds would be a ma jor observational step in constraining our understanding of the role magnetic fields play in the transition from atomic to molecular clouds. A reliable upper limit would also be extremely important in restricting the role of magnetic support in cloud evolution.
