Ore is working on relativistic magnetohydrodynamic simulations and analytic models of jets propagation and radiation in the context of gamma-ray bursts in collapsing massive stars and in Neutron star mergers.

X-shaped Radio Galaxy Morphology: 3-dimensional movie of density
When astronomers use radio telescopes to gaze into the night sky, they typically see elliptical-shaped galaxies, with twin jets blasting from either side of their central supermassive black hole. But every once in a while — less than 10% of the time — astronomers might spot something special and rare: An X-shaped radio galaxy, with

X-shaped radio galaxies might form more simply than expected
A still image taken from the 3D simulation of the natural development of an X-shaped jet. The gas (bright red) falls into the black hole, which launches a pair of relativistic jets (light blue). The jets propagate vertically and shock the ambient gas (dark red). The older cavities (dark blue) buoyantly rise at an angle
