astro-ph/0704.1125 High Galactic latitude interstellar neutral hydrogen (HI) structure and associated acoustic-scale WMAP hot spots

Authors: Gerrit L. Verschuur

Associations have been found between interstellar neutral hydrogen (HI) emission morphology and small-scale structure observed by the Wilkinson Microwave Anisotropy Probe (WMAP) in a Target Area bounded by l = 60 deg & 180 deg, b = 30 deg & 70 deg. ...

Is some part of the angular power spectrum at about a degree (first "Doppler peak") due to interacting/colliding HI clouds around our Galaxy?
