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…
Testing the Kerr black hole hypothesis using X-ray reflection spectroscopy
Cosimo Bambi, Alejandro Cardenas-Avendano, Thomas Dauser +2
We present the first X-ray reflection model for testing the assumption that the metric of astrophysical black holes is described by the Kerr solution. We employ the formalism of th…
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…
