Method for detecting a boson star at Sgr A* through gravitational lensing
Amitai Y. Bin-Nun
Observations of the Sgr A* region in the galactic center confirm the presence of a large amount of matter in a small volume, leading to the consensus that a black hole exists there…
Strong Gravitational Lensing by Sgr A*
Amitai Y. Bin-Nun
In recent years, there has been increasing recognition of the potential of the galactic center as a probe of general relativity in the strong field. There is almost certainly a bla…
Lensing By Sgr A* as a Probe of Modified Gravity
Amitai Y. Bin-Nun
We show that a possible astrophysical experiment, detection of lensed images of stars orbiting close to Sgr A*, can provide insight into the form of the metric around a black hole.…
Relativistic Images in Randall-Sundrum II Braneworld Lensing
Amitai Y. Bin-Nun
In this paper, we explore the properties of gravitational lensing by black holes in the Randall-Sundrum II braneworld. We use numerical techniques to calculate lensing observables…
