Information Field Theory with JAX infers Air Shower Electric Currents from Antenna Signal Traces
Maximilian Straub, Torsten Enßlin, Martin Erdmann +2
Direct imaging of cosmic-ray-induced particle showers during daylight is a long-standing challenge in astroparticle physics. A promising avenue for capturing images of these shower…

Electric Field Reconstruction with Information Field Theory
Simon Strähnz, Tim Huege, Philipp Frank +1
Reconstructing the electric field from the measured voltages in an antenna, unfolding the antenna response, comes with several problems. Due to the noisiness of the signal it is of…

Towards a Field Based Bayesian Evidence Inference from Nested Sampling Data
Margret Westerkamp, Jakob Roth, Philipp Frank +2
Nested sampling (NS) is a stochastic method for computing the log-evidence of a Bayesian problem. It relies on stochastic estimates of prior volumes enclosed by likelihood contours…
