Ejection-accretion connection in NLS1 AGN 1H 1934-063
Yerong Xu, Ciro Pinto, Erin Kara +7
Accretion and ejection of matter in active galactic nuclei (AGN) are tightly connected phenomena and represent fundamental mechanisms regulating the growth of the central supermass…
Wind-luminosity evolution in NLS1 AGN 1H 0707-495
Yerong Xu, Ciro Pinto, Stefano Bianchi +7
Ultra-fast outflows (UFOs) have been detected in the high-quality X-ray spectra of a number of active galactic nuclei (AGN) with fairly high accretion rates and are thought to sign…
The Nature of Soft Excess in ESO 362-G18 Revealed by XMM-Newton and NuSTAR Spectroscopy
Yerong Xu, Javier A. García, Dominic J. Walton +3
We present a detailed spectral analysis of the joint XMM-Newton and NuSTAR observations of the active galactic nuclei (AGN) in the Seyfert 1.5 Galaxy ESO 362-G18. The broadband ($0…
Singularity-free black holes in conformal gravity: new observational constraints
Menglei Zhou, Askar B. Abdikamalov, Dimitry Ayzenberg +4
We consider the family of singularity-free rotating black hole solutions in Einstein's conformal gravity found in Bambi, Modesto & Rachwal (2017) and we constrain the value of the…
Testing general relativity with supermassive black holes using X-ray reflection spectroscopy
Askar B. Abdikamalov, Dimitry Ayzenberg, Cosimo Bambi +7
In this paper, we review our current efforts to test General Relativity in the strong field regime by studying the reflection spectrum of supermassive black holes. So far we have a…
A study of the strong gravity region of the black hole in GS 1354-645
Yerong Xu, Sourabh Nampalliwar, Askar B. Abdikamalov +5
It is thought that the spacetime metric around astrophysical black holes is well described by the Kerr solution of Einstein's gravity. However, a robust observational evidence of t…
