tomography

This paper introduces CoroNeRF for joint reconstruction of 3D electron density and temperature fields from multiview solar observations, highlighting that image fidelity does not guarantee physical field fidelity and proposing seed-based error localization methods.

AION-1, an astronomical foundation model, is biased by survey detection channels and catalogue metadata, leading to significant errors in tomographic mean redshifts. The study quantifies these biases through causal interventions and proposes withholding the detection channel to mitigate the issue.
