Binary AGNs simulations with radiation pressure reveal a new duty cycle, and a reduction of gravitational torque, through 'minitori' structures
Binary AGNs simulations with radiation pressure reveal a new duty cycle, and a reduction of gravitational torque, through 'minitori' structures
We produce the first set of radiation hydrodynamics simulations of
binary active galactic nuclei (AGNs) at parsec-scale separation in
scale-model simulations. We use SPH for hydrodynamics, and raytracing to
calculate optical depths and radiation pressure from the two AGNs. We
confirm that, without radiation pressure, the sign of gravitational
torque is sensitive to the binary parameters, although in one of our two
orbital configurations the binary should coalesce in a time-scale of

Abstract
We produce the first set of radiation hydrodynamics simulations of
binary active galactic nuclei (AGNs) at parsec-scale separation in
scale-model simulations. We use SPH for hydrodynamics, and raytracing to
calculate optical depths and radiation pressure from the two AGNs. We
confirm that, without radiation pressure, the sign of gravitational
torque is sensitive to the binary parameters, although in one of our two
orbital configurations the binary should coalesce in a time-scale of
