Resumen:
We study simulated images generated from an accretion disk surroundingthe supermassive black hole hosted in the nearby galaxy M87.We approach the problem employing very simple accreting models inspired frommagnetohydrodynamical simulations and introducing a new recipe for dealing with the combined integration of the geodesic and geodesic deviation equations in Kerr spacetime,which allows for a convenient and efficient way to manage the system of equations.The geometry of the basic emission model is given by a two temperature thin disk in the equatorial plane of the black hole supplemented by an asymmetric bar structure.We show that this configuration permits to generate the most salient features appearingin the EHT Collaboration images of M87with impressive fidelity.
