Bending instabilities at the origin of persistent warps
Y. Revaz, D. Pfenniger
Based on N-body simulations, we show that realistic galactic disks are subject to bending instabilities of fire-hose type when the disks are substantially self-gravitating, that is…

N-body simulations of warped galaxies
Yves Revaz, Daniel Pfenniger
Two methods generating warped galaxies with N-body simulations are presented. One uses an external potential as a disturber while the other is based on material accretion. The resu…
