Understanding the physical mechanisms that control galaxy formation is a fundamental
challenge in contemporary astrophysics. Recent advances in the field of astrophysical …

The present white paper is submitted as part of the “Snowmass” process to help inform the
long-term plans of the United States Department of Energy and the National Science …

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. The existence of magnetic fields in the circumgalactic medium (CGM) is largely
unconstrained. Their detection is important as magnetic fields can have a significant impact …

Most of the visible matter in the Universe is ionized, so that cosmic magnetic fields are quite
easy to generate and due to the lack of magnetic monopoles hard to destroy. Magnetic fields …

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 …

Molecular gas is believed to be the fuel for star formation and nuclear activity in Seyfert
galaxies. To explore the role of magnetic fields in funneling molecular gas into the nuclear …

In star-forming galaxies, the far-infrared (FIR) and radio-continuum luminosities obey a tight
empirical relation over a large range of star-formation rates (SFR). To understand the …

The phenomenon of Faraday rotation of linearly polarized synchrotron emission in a
magneto-ionized medium has been understood and studied for decades. But since the …

Cosmic rays (CRs) are an important component in the interstellar medium, but their effect on
the dynamics of the disc–halo interface (< 10 kpc from the disc) is still unclear. We study the …
