On the propagation of bulges and buckles
Webthat B/PS bulges could be due to the thickening of bars in the disks of spiral galaxies. They showed that soon after a bar develops through the usual bar instability, it buckles, thickens, and settles with a larger velocity dispersion and thickness. When highly inclined, the bar then appears peanut-shaped WebAs long as the external pressure is less than the propagation pressure threshold, a buckle cannot propagate. A number of empirical relationships have been published for …

Destructive civic activity may be most likely when a youth bulge is accompanied by depressed economic conditions (Huntington, 1996; Urdal, 2002), because poor
