The torquing of circumnuclear accretion disks by stars and the evolution of massive black holes
Michal Bregman, Tal Alexander
An accreting massive black hole (MBH) in a galactic nucleus is surrounded by a dense stellar cluster. We analyze and simulate numerically the evolution of a thin accretion disk due…
Accretion disk warping by resonant relaxation: The case of maser disk NGC4258
Michal Bregman, Tal Alexander
The maser disk around the massive black hole (MBH) in active galaxy NGC 4258 exhibits an O(10 deg) warp on the O(0.1 pc) scale. The physics driving the warp are still debated. Sugg…
On the Self-Affine Roughness of a Crack Front in Heterogeneous Media
Eran Bouchbinder, Michal Bregman, Itamar Procaccia
The long-ranged elastic model, which is believed to describe the evolution of a self-affine rough crack-front, is analyzed to linear and non-linear orders. It is shown that the non…
Diffusion induced mode switching in avalanching systems
Michal Bregman
Most avalanching systems in nature should involve diffusive processes as well which can change the behavior of such systems and should be taken into account. We examine the effects…
