Main Question or Discussion Point

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?
