| Abstract: |
GPIPS, the Galactic Plane Infrared Polarization Survey, is collecting new data
to answer key questions concerning the Galactic magnetic field. GPIPS uses
the Mimir instrument in wide-field (10×10 arcmin FOV, with 0.6 arcsec pixels) imaging
polarimetric mode on the 1.8 m Perkins telescope near Flagstaff, AZ. GPIPS consists
of observations of over 3,200 overlapping 9×9 arcmin field centers covering 76 square
degrees of the first Galactic quadrant. In each field, H-band (1.6 μm) linear
polarimetry is used to reveal the sky projection of the magnetic field traced by
unpolarized background stars. For each field, useful polarimetric data are obtained
down to H=12 mag, resulting in about 100-140 magnetic field direction per FOV.
Fields already observed include all stellar clusters, MAGPIS sources, many GLIMPSE
bubbles, most pulsar directions, as well as dark clouds and massive molecular clouds. |
