Synthetic gravitational lens image of the Sagittarius A black hole with a thin disk model
Ezequiel F. Boero, Osvaldo M. Moreschi
The images of Sagittarius A published by the Event Horizon Telescope (ETH) Collaboration in 2022 present features that were associated with an emission ring consistent with w…

Strong gravitational lens image of the M87 black hole with a simple accreting matter model
Ezequiel F. Boero, Osvaldo M. Moreschi
We study simulated images generated from an accretion disk surrounding the supermassive black hole hosted in the nearby galaxy M87. We approach the problem employing very simple ac…

Efficient gravitational lens optical scalars calculation of black holes with angular momentum
Ezequiel F. Boero, Osvaldo M. Moreschi
We provide new very simple and compact expressions for the efficient calculation of gravitational lens optical scalars for Kerr spacetime which are exact along any null geodesic. T…
