Accretion disk warping by resonant relaxation: the case of maser disk NGC 4258.
BREGMAN M. and ALEXANDER T.
Abstract (from CDS):
The maser disk around the massive black hole (MBH) in active galaxy NGC 4258 exhibits an O(10°) warp on the O(0.1 pc) scale. The physics driving the warp is still debated. Suggested mechanisms include torquing by relativistic frame dragging or by radiation pressure. We propose here a new warping mechanism: resonant torquing of the disk by stars in the dense cusp around the MBH. We show that resonant torquing can induce such a warp over a wide range of observed and deduced physical parameters of the maser disk.
