We are releasing the code for our recent paper on Fourier Neural Operators (FNOs) applied to magnetohydrodynamic turbulence. The repository contains a PyTorch implementation of a FNO trained to act as a surrogate for 2D MHD simulations of the Orszag–Tang vortex, a canonical plasma physics benchmark. Given a short initial window of simulation frames plus two physical parameters (kinematic viscosity…
This has been a long time coming, and I am thrilled that we are finally making this codebase public! Our group is releasing GPUmonty: a GPU-accelerated Monte Carlo radiative transfer code that simulates the appearance of hot gas falling onto a black hole. The big news is that our code is the first to solve this problem using GPUs, and it is over ten times faster than previous solutions. The entire…
Nature asked me to write a News & Views article on a recent hot result on little red dots. N&V articles explain the results of new research paper in a way that is accessible to a broad community of scientists outside the specific field, while giving the author’s opinion on the work. LRDs are the hottest thing in astronomy right now, and nobody really knows their nature (no pun intended). As you…
I was invited to give a review talk about relativistic jets from AGN in the ”AGN redemption" conference . The venue was at beautiful, humid Zihuatanejo. I haven't been in such a excruciatingly hot place since I lived in Porto Alegre, or when I visited Rio during summer. So if you are wondering if Zihuatanejo is warm at the end of October: yes sir! Very much so. Anyway, the organizers asked me to…
