Lyman edges in supermassive black hole binaries

open access: yes, 2014
We propose a new spectral signature for supermassive black hole binaries (SMBHBs) with circumbinary gas disks: a sharp drop in flux blueward of the Lyman limit. A prominent edge is produced if the gas dominating the emission in the Lyman continuum region

Supermassive black holes with stellar companions

open access: yesAIP Conference Proceedings, 1994
Low‐mass stars in close orbits around supermassive black holes in active galactic nuclei (AGN) may provide an important signature for testing the existence of supermassive black holes. Here we discuss how such systems can form by being ‘‘ground down’’ by their interaction with an AGN accretion disk and discuss the peculiarities of such binaries with ...

Strong field gravitational lensing by a charged Galileon black hole

open access: yes, 2016
Strong field gravitational lensings are dramatically disparate from those in the weak field by representing relativistic images due to light winds one to infinity loops around a lens before escaping.
