Testing black hole no-hair theorem with OJ287
M. J. Valtonen, S. Mikkola, H. J. Lehto +3
We examine the ability to test the black hole no-hair theorem at the 10% level in this decade using the binary black hole in OJ287. In the test we constrain the value of the dimens…

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…
