Constraining dynamo theories of magnetic field origin by observation is indispensable but
challenging, in part because the basic quantities measured by observers and predicted by …

Radio continuum observations of external galaxies provide us with an excellent outside view
on the distribution of cosmic-ray electrons in the disc and halo. In this review, we summarise …

Context. Cosmic rays and magnetic fields are key ingredients in galaxy evolution, regulating
both stellar feedback and star formation. Their properties can be studied with low-frequency …

Jellyfish galaxies have long tails of gas that is stripped from the disk by ram pressure due to
the motion of galaxies in the intracluster medium in galaxy clusters. Here, we present the …

The physics of Cosmic ray (CR) transport remains a key uncertainty in assessing whether
CRs can produce galaxy-scale outflows consistent with observations. In this paper, we …

Ram pressure stripping is a crucial evolutionary driver for cluster galaxies. It is thought to be
able to accelerate the evolution of their star formation, trigger the activity of their central …

Synchrotron emission is one of few observable tracers of galactic magnetic fields (B) and
cosmic rays (CRs). Much of our understanding of B in galaxies comes from utilizing …

Abstract The Hot Universe Baryon Surveyor (HUBS) is a proposed space-based X-ray
telescope for detecting X-ray emissions from the hot gas content in our universe. With its …

Context. The magnetic field in spiral galaxies is known to have a large-scale spiral structure
along the galactic disk and is observed as X-shaped in the halo of some galaxies. While the …

Molecular gas plays a critical role in explaining the quiescence of star formation (SF) in
massive isolated spiral galaxies, which could be a result of either the low molecular gas …
