TLDR
In this article, the relativistic effects acting on both the reflection continuum and the iron line from accretion discs around rotating black holes were investigated in Kerr space-time, and it was shown that the observed EW of the lines is substantially enlarged when the black hole rotates rapidly and/or the source of illumination is near above the hole.Abstract:
ABSTRA C T We performed detailed calculations of the relativistic effects acting on both the reflection continuum and the iron line from accretion discs around rotating black holes. Fully relativistic transfer of both illuminating and reprocessed photons has been considered in Kerr space‐time. We calculated overall spectra, line profiles and integral quantities, and present their dependences on the black hole angular momentum. We show that the observed EW of the lines is substantially enlarged when the black hole rotates rapidly and/or the source of illumination is near above the hole. Therefore, such calculations provide a way to distinguish between different models of the central source.read more

General relativistic boson stars
TL;DR: In this article, the authors focus on the possibilities of detecting the various subtypes of (excited) BSs: possible signals include gravitational redshift and (micro-)lensing, emission of gravitational waves, or, in the case of a giant BS, its dark matter contribution to the rotation curves of galactic halos.

Broad Iron Lines in Active Galactic Nuclei
TL;DR: The fluorescent line in the X-ray band at 6.4-6.9 keV is the strongest such line and is seen in the spectrum of many active galactic nuclei and, in particular, Seyfert galaxies.

A light bending model for the X-ray temporal and spectral properties of accreting black holes
TL;DR: In this article, the authors explore a light bending model in which they assume a primary source of X-rays located close to a central, maximally rotating Kerr black hole and illuminating both the observer at infinity and the accretion disc.

TL;DR: In this paper, a detailed, general relativistic approach to model this irradiation for different geometries of the primary X-ray source is presented, including the standard point source on the rotational axis as well as more jet-like sources, which are radially elongated and accelerating.

The Mathematical Theory of Black Holes
TL;DR: In a course of lectures on the underlying mathematical structures of classical gravitation theory given in 1978, Brandon Carter as discussed by the authors began with the statement ‘If I had been asked five years ago to prepare a course for recent developments in classical gravity theory, I would not have hesitated on the classical theory of black holes as a central topic of discussion. But I am grateful to them for their courtesy in assigning to me this privilege.
