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…
The Baryonic Tully-Fisher relation revisited
D. Pfenniger, Y. Revaz
The Baryonic Tully-Fisher relation (BTF) can be substantially improved when considering that the galactic baryonic mass is likely to consist not only from the detected baryons, sta…
A Unified Picture of Disk Galaxies where Bars, Spirals and Warps Result from the Same Fundamental Causes
Daniel Pfenniger, Yves Revaz
Bars and spiral arms have played an important role as constraints on the dynamics and on the distribution of dark matter in the optical parts of disk galaxies. Dynamics linked to t…
Bending instabilities at the origin of persistent warps: a new constraint on dark matter halos
Yves Revaz, Daniel Pfenniger
A substantial fraction of the warps in spiral galaxies may result from bending instabilities if the disks are essentially self-gravitating. With N-body simulations, we show that ga…
