We review numerical methods for simulations of cosmic ray (CR) propagation on galactic
and larger scales. We present the development of algorithms designed for …

This is a review of the status of efforts to model the large-scale Galactic magnetic field
(GMF). Though important for a variety of astrophysical processes, the GMF remains poorly …

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 …

Primordial magnetic fields (PMFs) could explain the large-scale magnetic fields present in
the universe. Inflation and phase transitions in the early universe could give rise to such …

Cosmic rays (CRs) are a dynamically important component of the interstellar medium (ISM)
of galaxies. The∼ GeV CRs that carry most CR energy and pressure are likely confined by …

The presence of magnetic fields in many astrophysical objects is due to dynamo action,
whereby a part of the kinetic energy is converted into magnetic energy. A turbulent dynamo …

Pulsars can act as an excellent probe of the Milky Way magnetic field. The average strength
of the Galactic magnetic field component parallel to the line of sight can be estimated as …

Magnetic fields in galaxies and galaxy clusters are amplified from a very weak seed value to
the observed G strengths by the turbulent dynamo. The seed magnetic field can be of …

Context. The details of cosmic-ray transport have a strong impact on galaxy evolution. The
peak of the cosmic-ray energy distribution is observable in the radio continuum using the …

High-spatial-resolution H i observations have led to the realization that the nearby (within
few hundreds of parsecs) Galactic atomic filamentary structures are aligned with the ambient …
