We continue to explore the dynamics of a heavy quark in strongly coupled rotating quark-gluon plasma within holographic framework. use 5d Kerr-AdS black hole with two arbitrary parameters describe plasma. present relations for drag force acting on both rotating- and static-at-infinity frames choice rotational parameters. also calculate thermal mass static different show that at high-$T$ limit d...

We present some features of Kerr black hole horizons that are replicated on orbits accessible to outside observers. use the concepts horizon confinement and replicas show outer there exist photon whose frequencies contain information about inner can, in principle, be detected through emission spectra holes. It is shown such close rotation axis geometry. argue these results could used recognize ...

We consider the Blandford-Znajek process of electromagnetic extraction energy from a general axially symmetric asymptotically flat slowly rotating black hole. Using parametrization black-hole spacetime we construct formulas for flux magnetic field and rate extraction, which are valid not only Kerr spacetime, but also its arbitrary deformations. show that in dominant order these quantities depen...

We conduct an analysis of the quasi-normal modes for generic spin perturbations Kerr black hole using isomonodromic method. The strategy consists solving Riemann-Hilbert map relating accessory parameters differential equations involved to monodromy properties solutions, $\tau$-function Painlev\'e V transcendent. show good accordance method with literature rotation parameter $a<M$. In extremal l...

The occurrence of chaos for test particles moving around a slowly rotating black hole with a dipolar halo is studied using Poincaré sections. We find a novel effect, particles with angular momentum opposite to the black hole rotation have larger chaotic regions in phase space than particles initially moving in the same direction. 04.20.Jb, 04.70.Bw, 05.45.+b.
