Join a seminar about inverting observations to understand the Sun

October 24, 2025

On Wednesday, November 5, from 2:00 pm to 3:00 pm MT, join NSF NCAR’s High Altitude Observatory (HAO) for a colloquium. The talk is entitled "Invert Everything Everywhere All at Once."

Christoph Keller, of the National Solar Observatory (NSO), will discuss how physics-informed neural networks can be used for extreme inversion problems, such as deriving velocities, densities, and temperatures from continuum images. This approach aims to create physically self-consistent models of the Sun without explicitly solving physics equations, even predicting its evolution.

This is a hybrid event. In-person participants can join at NSF NCAR’s Center Green Campus (CG1), room 3131, at 3085 Center Green Drive, Boulder, CO 80301. Virtual participants can join here. 

For more information, see the event page or contact organizers.
