Black hole image computed with Sage

[Eric Gourgoulhon]

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:

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).

Best wishes,

Eric.

Very cool! Thank you for pointing it out.

They should re-post that to social media... I'm pretty sure everyone
else ignored the "photo of a black hole" announcement on April 1st just
like I did.

Very cool! Thank you for pointing it out.
