Galactic Plane Infrared Polarization Survey
The Galactic Plane Infrared Polarization Survey was a near-infrared astronomical program that mapped polarized starlight across the Milky Way to probe interstellar magnetic fields, dust, and star-forming regions. The project linked observational efforts from institutions such as the University of Florida, Lowell Observatory, and the National Optical Astronomy Observatory with instrumentation developed for the Perkins Telescope and the Mimir instrument. It complements surveys like the Two Micron All Sky Survey, the Spitzer Space Telescope programs, and the Planck polarization maps while informing studies by teams at the Harvard–Smithsonian Center for Astrophysics, the Max Planck Institute for Astronomy, and the Space Telescope Science Institute.
GPIPS targeted the inner Galactic plane to measure linear polarization of background starlight in the near-infrared, enabling inference of magnetic field orientation and magnetic strength in regions of high extinction. The survey strategy built on legacy work from the Cerro Tololo Inter-American Observatory, the Kitt Peak National Observatory, and the Anglo-Australian Observatory, and it interfaced with catalogs from the Sloan Digital Sky Survey, the Gaia mission, and the Two Micron All Sky Survey to provide astrometric, photometric, and polarimetric cross-matching. GPIPS also related to theoretical studies developed at the Princeton University, the California Institute of Technology, and the University of Cambridge on magnetohydrodynamic turbulence and star formation in regions studied by the Herschel Space Observatory and the James Clerk Maxwell Telescope.
The survey used the Mimir near-infrared polarimeter mounted on the Perkins 1.8-meter telescope operated by the Lowell Observatory at the Andrews Observatory site, with hardware contributions from teams at the University of Massachusetts Amherst and the University of Arizona. The observing plan optimized coverage along the Galactic midplane in fields coordinated with the Very Large Array maps, the FCRAO molecular line surveys, and the Arecibo Observatory legacy data to enable multiwavelength comparison. Instrument calibration referenced standard stars from lists maintained by the European Southern Observatory and procedures developed at the Royal Observatory, Edinburgh and the National Radio Astronomy Observatory. Project management involved collaborations with personnel associated with the National Science Foundation and the NASA Goddard Space Flight Center.
Observations were acquired in H-band near 1.6 microns across hundreds of fields, employing polarimetric cycles and dithering strategies informed by methodology from the Hubble Space Telescope instrument teams and the Subaru Telescope polarimetry efforts. Data reduction pipelines used software frameworks and algorithms paralleled in projects at the Max Planck Institute for Radio Astronomy, the Jet Propulsion Laboratory, and the Lawrence Berkeley National Laboratory for background subtraction, flat-fielding, and polarization vector estimation. Cross-identification and astrometry used catalogs from Gaia, the Two Micron All Sky Survey, and the Wide-field Infrared Survey Explorer, while spectral energy distribution matching leveraged results from the Spitzer Space Telescope and the Herschel Space Observatory. Quality assurance and systematic-error analysis referenced techniques developed at the European Space Agency and the Institute of Astronomy, Cambridge.
GPIPS produced polarimetric catalogs and maps revealing coherent magnetic field orientations across molecular clouds, infrared dark clouds, and star-forming complexes associated with objects cataloged by the Arecibo Observatory, the FCRAO, and surveys of the Galactic Ring Survey. The survey provided new insights into magnetic field alignment relative to filamentary structures identified in Herschel Space Observatory images and regions previously studied by the Spitzer Space Telescope Galactic plane programs. GPIPS data supported measurements of the Chandrasekhar–Fermi method in molecular clouds analyzed by research groups at the Max Planck Institute for Astronomy, the University of Colorado Boulder, and the Princeton University Observatory, and informed targeted follow-up with the Atacama Large Millimeter/submillimeter Array and the Very Large Telescope. The catalogs enabled cross-studies with stellar populations from Gaia and the photometric databases of the Two Micron All Sky Survey and the United Kingdom Infrared Telescope.
The survey constrained the role of magnetic fields in regulating star formation efficiency and the morphology of interstellar structures, supporting theoretical frameworks advanced at the Harvard–Smithsonian Center for Astrophysics, the University of Cambridge, and the California Institute of Technology. GPIPS results influenced models of magnetohydrodynamic turbulence produced by research groups at the Max Planck Institute for Astrophysics, the Princeton Plasma Physics Laboratory, and the Kavli Institute for Theoretical Physics. Comparisons with polarization measurements from the Planck mission and extinction mapping from the Two Micron All Sky Survey refined estimates of dust grain alignment mechanisms developed by teams at the NASA Ames Research Center and the Jet Propulsion Laboratory. The dataset contributed to interpretations of feedback processes in regions observed by the Chandra X-ray Observatory and the Fermi Gamma-ray Space Telescope.
GPIPS released calibrated polarization catalogs, vector maps, and image mosaics that have been archived and served to the community through data centers associated with the National Optical Astronomy Observatory, the Infrared Science Archive, and institutional repositories at the University of Florida and the Lowell Observatory. Legacy products have been used in subsequent surveys and analyses by groups at the Max Planck Institute for Astronomy, the Space Telescope Science Institute, and the European Southern Observatory, and have been cited in studies leveraging data from ALMA, the Very Large Telescope, and the James Webb Space Telescope. The GPIPS legacy continues to inform observational programs funded by the National Science Foundation and the National Aeronautics and Space Administration.
