Low-frequency measurements of synchrotron absorbing HII regions and modeling of observed synchrotron emissivity. (2019)

Keywords : cosmic rays - ISM magnetic fields - HII regions - Galaxy: structure - radio continuum: ISM - catalogs

Abstract:Cosmic rays (CRs) and magnetic fields are dynamically important components in the Galaxy, and their energy densities are comparable to that of the turbulent interstellar gas. The interaction of CRs and Galactic magnetic fields (GMF) produces synchrotron radiation clearly visible in the radio regime. Detailed measurements of synchrotron radiation averaged over the line-of-sight (LOS), so-called synchrotron emissivities, can be used as a tracer of the CR density and GMF strength. Our aim is to model the synchrotron emissivity in the Milky Way using a three-dimensional dataset instead of LOS-integrated intensity maps ...(more)

In this work we have combined existing low-frequency observations of HII regions, from five papers, with known distances in the Milky Way, into one catalog.
