We perform general-relativistic simulations of self-gravitating black hole disks in which the spin is significantly tilted (45\ifmmode^\circ\else\textdegree\fi{} and 90\ifmmode^\circ\else\textdegree\fi{}) with respect to angular momentum disk disk--to--black mass ratio 16--28%. The holes are rapidly spinning dimensionless spins up $\ensuremath{\sim}0.97$. These first self-consistent hydrodynami...

Abstract We study neutrinos gravitationally scattered off a rotating supermassive black hole which is surrounded by thin accretion disk with realistic magnetic field. Neutrinos are supposed to be Dirac particles having nonzero moment. move along arbitrary trajectories, the incoming flux being parallel equatorial plane. exactly account for influence of both gravity and field on neutrino motion i...
