Radio jets in NGC 4151: where eMERLIN meets HST
D. R. A. Williams, I. M. McHardy, R. D. Baldi +11
We present high-sensitivity eMERLIN radio images of the Seyfert galaxy NGC 4151 at 1.5 GHz. We compare the new eMERLIN images to those from archival MERLIN observations in 1993 to…

Measuring Black Hole Spin in OJ287
M. Valtonen, S. Mikkola, H. J. Lehto +8
We model the binary black hole system OJ287 as a spinning primary and a non-spinning secondary. It is assumed that the primary has an accretion disk which is impacted by the second…

Measuring the spin of the primary black hole in OJ287
M. J. Valtonen, S. Mikkola, D. Merritt +7
The compact binary system in OJ287 is modelled to contain a spinning primary black hole with an accretion disk and a non-spinning secondary black hole. Using Post Newtonian (PN) ac…
