The Galactic Plane Infrared Polarization Survey (GPIPS) has completed its initial season of H-band (1.6 microns) data collection using the Mimir near-infrared instrument in linear imaging polarimetry mode on the 1.8m Perkins Telescope outside Flagstaff, Arizona. This key project for the Perking Telescope seeks to answer key questions about the nature of the magnetic field and the aligned dust grains used to trace the field for small-scale star-forming regions, medium scale molecular and atomic cloud regions, and large-scale spiral arm and interarm regions. The GPIPS survey goals are to survey about 48 square degrees of the northern galactic disk to H=12th magnitude with polarimetric sensitivity to 0.1-0.2 percent, and create publically available polarimetric and photometric catalogs from the survey data. GPIPS observations were conducted during the June/July and September months of 2006. These first observations covered about 150 of the 3,200 9x9 arcmin spaced grid of field centers slated for polarimetry using the 10x10 arcmin FOV of the Mimir instrument. The field centers were chosen to cover all known inner galaxy stellar clusters within 1 degree latitude of the midplane as well as a couple of nearby molecular clouds already surveyed in 13CO by the Galactic Ring Survey. A sampling of the images and polarimetry drawn from these initial observations will be highlighted in this poster.
GPIPS is partially supported by a grant from the NSF (AST 06-07500) and by Boston University's continuing partnership agreement with Lowell Observatory.
