3D Moving-mesh Hydrodynamical Simulations of Wind/Jet Driven Ultraluminous X-ray Source Bubbles
Jiahui Huang, Ken Ohsuga, Hua Feng +1
We perform 3 dimensional moving-mesh hydrodynamical simulations of bubble nebulae around ultraluminous X-ray sources, using state-of-the-art software AREPO. We use a Monte-Carlo me…
GR-RMHD Simulations of Super-Eddington Accretion Flows onto a Neutron Star with Dipole and Quadrupole Magnetic Fields
Akihiro Inoue, Ken Ohsuga, Hiroyuki R. Takahashi +2
Although ultraluminous X-ray pulsars (ULXPs) are believed to be powered by super-Eddington accretion onto a magnetized neutron star (NS), the detailed structures of the inflow-outf…
General Relativistic Radiation Magnetohydrodynamics Simulations of Precessing Tilted Super-Eddington Disks
Yuta Asahina, Ken Ohsuga
We perform a three-dimensional general relativistic radiation magnetohydrodynamics simulation of a tilted super-Eddington accretion disk around the spinning black hole (BH). The di…
Radio Images inside Highly Magnetized Jet Funnels Based on Semi-Analytic GRMHD Models
Taiki Ogihara, Tomohisa Kawashima, Ken Ohsuga
By performing general relativistic radiative transfer calculations, we show the radio images of relativistic jets including highly magnetized regions inside jet funnels, based on s…
Three-dimensional radiation hydrodynamics simulations of wandering intermediate-mass black holes considering the anisotropic radiation and dust sublimation
Erika Ogata, Ken Ohsuga, Hajime Fukushima +1
By performing three-dimensional radiation hydrodynamics simulations, we study Bondi-Hoyle-Lyttleton accretion onto intermediate-mass black holes (BHs) wandering in the dusty gas. H…
The High Energy X-ray Probe (HEX-P): Studying Extreme Accretion with Ultraluminous X-ray Sources
Matteo Bachetti, Matthew J. Middleton, Ciro Pinto +25
Ultraluminous X-ray sources (ULXs) represent an extreme class of accreting compact objects: from the identification of some of the accretors as neutron stars to the detection of po…
