Hi All, As you may have heard in the news, the Event Horizon Telescope collaboration will release tomorrow the very first observed image of the close vicinity of a black hole: https://eventhorizontelescope.org/blog/media-advisory-first-results-event-horizon-telescope-be-presented-april-10th
In connection with this event, you may find a simulated black hole image, entirely computed with SageMath by Florentin Jaffredo, at https://sagemanifolds.obspm.fr/gallery.html The Jupyter notebook generating the image is https://nbviewer.jupyter.org/github/sagemanifolds/SageManifolds/blob/master/Notebooks/SM_black_hole_rendering.ipynb The computation relies on the integration of lightlike geodesics in a Lorentzian manifold that has been implemented in SageMath by Karim Van Aeslt and Florentin Jaffredo: http://doc.sagemath.org/html/en/reference/manifolds/sage/manifolds/differentiable/integrated_curve.html As a side note, the notebook runs well with both Python2 and Python3 versions of SageMath (>= 8.5).
