Virgo: Scalable Unsupervised Classification of Cosmological Shock Waves. (arXiv:2208.06859v3 [astro-ph.IM] UPDATED)

Cosmological shock waves are essential to understanding the formation of
cosmological structures. To study them, scientists run computationally
expensive high-resolution 3D hydrodynamic simulations. Interpreting the
simulation results is challenging because the resulting data sets are enormous,
and the shock wave surfaces are hard to separate and classify due to their
complex morphologies and multiple shock fronts intersecting. We introduce a
novel pipeline, Virgo, combining physical motivation, scalability, and
probabilistic robustness to tackle this unsolved unsupervised classification
problem. To this end, …
