Beamed emission from a neutron-star ULX in a GRRMHD simulation.

Abstract (from CDS):

We perform a global 2.5D general-relativistic radiation magnetohydrodynamic simulation of supercritical accretion onto a neutron star with a 2 x 1010 G dipolar magnetic field, as a model of a neutron-star-powered ultraluminous X-ray source (ULX). We compute a lower limit on the total luminosity of ∼2.5 LEdd, and find the radiation to be highly beamed by the accretion disk outflows. The apparent isotropic luminosity, which is a function of the viewing angle, reaches a maximum above 100 LEdd, consistent with the luminosities observed in ULXs.
