Observational evidence points to a red supergiant (RSG) progenitor for SN 2023ixf. The
progenitor candidate has been detected in archival images at wavelengths (≥ 0.6 μm) …

The sky at MeV energies is currently poorly explored. Here we present an innovative
mission concept that builds upon the heritage of past and current missions improving the …

In this white paper we introduce the IMAGINE Consortium and its scientific background,
goals and structure. The purpose of the consortium is to coordinate and facilitate the efforts …

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. 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. 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 …

Solving Bayesian inference problems approximately with variational approaches can
provide fast and accurate results. Capturing correlation within the approximation requires an …

The 21 cm emission from atomic hydrogen (HI) is one of the most important tracers of the
structure and dynamics of the interstellar medium. Thanks to Galactic rotation, the line is …

With the development of modern radio interferometers, wide-field continuum surveys have
been planned and undertaken, for which accurate wide-field imaging methods are essential …

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 …
