Toward a realistic test of black-hole movie correlations as a probe of extreme lensing
Barbora Bezděková, Shahar Hadar
In an optically thin setting, gravitational lensing around a black hole creates multiple delayed images of any localized source, appearing at different positions on the observer's…
Light deflection in axially symmetric stationary spacetimes filled with a moving medium
Christian Pfeifer, Barbora Bezděková, Oleg Yu. Tsupko
The deflection of light rays near gravitating objects can be influenced not only by gravity itself but also by the surrounding medium. Analytical studies of such effects are possib…
Extreme-Lensing Signatures Revealed by Correlations of Simulated Black-Hole Movies
Barbora Bezděková, Shahar Hadar, George Wong +1
A black hole's gravitational pull can deflect light rays to an arbitrary degree. As a result, any source fluctuation near the black hole creates multiple lagged images on an observ…
Deflection of light rays in a moving medium around a spherically symmetric gravitating object
Barbora Bezděková, Oleg Yu. Tsupko, Christian Pfeifer
In most analytical studies of light ray propagation in curved spacetimes around a gravitating object surrounded by a medium, it is assumed that the medium is a cold nonmagnetized p…
Radiation in the black hole - plasma system: propagation in equatorial plane
Vladimír Balek, Barbora Bezděková, Jiří Bičák
Effect of cold plasma on the form of rays propagating in the equatorial plane of a rotating black hole is investigated. Two kinds of regions in the radius-impact parameter plane al…
Light Deflection in Plasma in the Hartle-Thorne Metric and in Other Axisymmetric Spacetimes with a Quadrupole Moment
Barbora Bezdekova, Jiri Bicak
The light propagation in plasma medium around stationary gravitating objects is studied in the geometrical optics limit. Static metrics with quadrupole moments are considered, howe…
