A Lack of Resolved Near-Infrared Polarization Across the Face of M51

arXiv:1211.4248 · doi:10.1088/2041-8205/761/2/L28

Abstract

The galaxy M51 was observed using the Mimir instrument on the Perkins telescope to constrain the resolved H-band (1.6 m) polarization across the galaxy. These observations place an upper limit of on the -band polarization across the face of M51, at 0.6 arcsecond pixel sampling. Even with smoothing to coarser angular resolutions, to reduce polarization uncertainty, the -band polarization remains undetected. The polarization upper limit at -band, when combined with previous resolved optical polarimetry, rules out a Serkowski-like polarization dependence on wavelength. Other polarization mechanisms cannot account for the observed polarization ratio () across the face of M51.
