Sprial galaxies - Are the axes of rotation of the purely random? This article: http://adsabs.harvard.edu/abs/2005astro.ph.11680T suggests the axes are preferentially aligned with cosmic voids. precis: Disk galaxies' axes should be highly inclined relative to the plane boundary of the nearby large-scale structure - or cosmic void. This is an 'expected consequence' of the formation of anglular momentum of disk galaxies. They show a good statistical fit of the hypothesis against galaxy redshift survey data - 2 sets. Does someone have either an explanation or a link to something that explains the 'expected consqeuence' part of the formation of angular mometum in a disk galaxy?
