Iron K line of boson stars
Zheng Cao, Alejandro Cardenas-Avendano, Menglei Zhou +3
The present paper is a sequel to our previous work [Y. Ni et al., JCAP 1607, 049 (2016)] in which we studied the iron K line expected in the reflection spectrum of Kerr black ho…
Iron K line of Kerr black holes with scalar hair
Yueying Ni, Menglei Zhou, Alejandro Cardenas-Avendano +3
Recently, a family of hairy black holes in 4-dimensional Einstein gravity minimally coupled to a complex, massive scalar field was discovered~\cite{hbh}. Besides the mass and s…
Search for astrophysical rotating Ellis wormholes with X-ray reflection spectroscopy
Menglei Zhou, Alejandro Cardenas-Avendano, Cosimo Bambi +2
Recently, two of us have found numerically rotating Ellis wormholes as solutions of 4-dimensional Einstein gravity coupled to a phantom field. In this paper, we investigate possibl…
Testing the Kerr black hole hypothesis: comparison between the gravitational wave and the iron line approaches
Alejandro Cardenas-Avendano, Jiachen Jiang, Cosimo Bambi
The recent announcement of the detection of gravitational waves by the LIGO/Virgo collaboration has opened a new window to test the nature of astrophysical black holes. Konoplya &…
