Dear Einstein-Toolkit community,
my name is Mario Imbrogno and I am a Ph.D. student at the University of Calabria (UniCal, Cosenza, Italy) under the supervision of prof. Sergio Servidio.
Our research group had developed a spectral code to solve the Einstein equations via a pseudo-spectral technique [Meringolo C, Servidio S, and Veltri P "A spectral method algorithm for numerical simulations of gravitational fields." Classical and Quantum Gravity 38.7 (2021): 075027], and I am studying different cases of merging two and more black holes, in vacuum conditions.
Now I have to compute the apparent horizons (AHs) just for our initial conditions, and I have read that the Einstein Toolkit implements the AHFinderDirect, a code that can detect the AHs.
My questions are: is there a way to compute such AHs by, just uploading our 3D cartesian BSSN fields and using the AHFinderDirect code?
Who is(are) the user(s) that mainly use(s) such code? Who can I ask?
Where can I find a detailed guide in which I can learn how to upload my data using the AHFinderDirect code?
If someone will help us, there is no problem for us to include as a co-author of our paper.
Best regards,
Mario Imbrogno
