Spatial Correlation Between H-Alpha Emission and Infrared Cirrus
A. Kogut
Abstract
Cross-correlation of the DIRBE 100 micron survey with previously published H-alpha maps tests correlations between far-infrared dust and the warm ionized interstellar medium in different regions of the sky. A 10 x 12 deg patch at Galactic latitude b = -21 shows a correlation slope a0 = 0.85 +/- 0.44 Rayleighs / MJy sr significant at 97% confidence. A set of H-alpha images over the north celestial polar cap yields a weaker correlation slope a0 = 0.34 +/- 0.33 Rayleighs / MJy sr. Combined with observations from microwave anisotropy experiments, the data show roughly similar correlations on angular scales 0.7 deg to 90 deg. Microwave experiments may observe more emission per unit dust emission than are traced by the same structures observed in H-alpha.
