Accretion-Ejection Instability and a "Magnetic Flood" scenario for GRS 1915+105
Michel Tagger
We present an instability, occurring in the inner region of magnetized accretion disks, which seems to be a good candidate to explain the low-frequency QPO observed in many X-ray b…
On the role of self-organised criticality in accretion systems
R. O. Dendy, P. Helander, M. Tagger
Self-organised criticality (SOC) has been suggested as a potentially powerful unifying paradigm for interpreting the structure of, and signals from, accretion systems. After review…
Dynamics of the asymmetries at galactic centers
F. Masset, M. Tagger
We propose a new dynamical mechanism to account for the bar off-centering observed in many barred galaxies. It is based on the presence of a m=1 density wave, non-linearly excited…
Non-linear generation of warps by spiral waves in galactic disks
F. Masset, M. Tagger
We present a new mechanism to explain the frequently observed and thus certainly permanent warping of spiral galaxies. We consider the possibility of non-linear coupling between th…
Propagation of warps in moderately thick disks
F. Masset, M. Tagger
We show that the propagation of warps in gaseous disks can be strongly affected by compressional effects, when the thickness of the disk is taken into account. The physical reason…
