How frequent are close supermassive binary black holes in powerful jet sources?
(2019-01-01)
Supermassive black hole binariesmay be detectable by an upcoming suite of gravitationalwave experiments. Their binary nature can also be revealed by radio jets via a short-period precession driven by the orbital motion as ...
A New Solution to the Plasma Starved Event Horizon Magnetosphere: Application to the Forked Jet in M87
(2018-06-22)
Very Long Baseline Interferometry observations at 86 GHz reveal an almost hollow jet in M87 with a forked morphology. The detailed analysis presented here indicates that the spectral luminosity of the central spine of the ...
Disks and Jets : Gravity, Rotation and Magnetic Fields
(2015-10)
Magnetic fields are fundamental to the dynamics of both accretion disks and the jets that they often drive. We review the basic physics of these phenomena, the past and current efforts to model them numerically with an ...
