Phys. Rev. D 76, 087301 (2007) [4 pages]Correlation between galactic HI and the cosmic microwave backgroundReceived 13 June 2007; revised 9 August 2007; published 17 October 2007 We revisit the issue of a correlation between the atomic hydrogen gas in our local galaxy and the cosmic microwave background, a detection of which has been claimed in some literature. We cross correlate the 21-cm emission of galactic atomic hydrogen as traced by the Leiden/Argentine/Bonn Galactic Hi survey with the 3-year cosmic microwave background data from the Wilkinson microwave anisotropy probe. We consider a number of angular scales, masks, and Hi velocity slices and find no statistically significant correlation. © 2007 The American Physical Society URL:
