Context. High-resolution 3D maps of interstellar dust are critical for probing the underlying
physics shaping the structure of the interstellar medium, and for foreground correction of …

Context. Self-calibration methods with the CLEAN algorithm have been widely employed in
very long baseline interferometry (VLBI) data processing in order to correct antenna-based …

We present the GPry algorithm for fast Bayesian inference of general (non-Gaussian)
posteriors with a moderate number of parameters. GPry does not need any pre-training …

Context. Ultra-high-energy cosmic rays (UHECRs) are highly energetic charged particles
with energies exceeding 10 18 eV. These energies are far greater than those achieved in …

Context. Radio interferometers measure frequency components of the sky brightness,
modulated by the gains of the individual radio antennas. Due to atmospheric turbulence and …

Strong gravitational lensing, a phenomenon rooted in the principles of general relativity,
grants us a unique window into the distant cosmos by offering a direct probe into dark matter …

Forward modeling approaches in cosmology have made it possible to reconstruct the initial
conditions at the beginning of the Universe from the observed survey data. However the …

Context. Magnetic fields permeate the diffuse interstellar medium (ISM) of the Milky Way,
and are essential to explain the dynamical evolution and current shape of the Galaxy …

Context. The spatial distribution of the gaseous components of the Milky Way is of great
importance for a number of different fields, for example, Galactic structure, star formation …

Information field theory (IFT), the information theory for fields, is a mathematical framework
for signal reconstruction and non-parametric inverse problems. Artificial intelligence (AI) and …
