Page 2: Research news on Radio continuum emission

Radio continuum emission as a research area focuses on broadband, non-line emission from astrophysical sources across radio frequencies, excluding narrow spectral lines. It encompasses thermal free–free (bremsstrahlung) emission from ionized gas, non-thermal synchrotron radiation from relativistic electrons in magnetic fields, and, at higher frequencies, thermal dust emission. Studies in this field use continuum observations to infer physical conditions such as magnetic field strengths, cosmic-ray electron populations, ionized gas densities, and star-formation rates in galaxies. It is central to characterizing active galactic nuclei, supernova remnants, H II regions, and the diffuse interstellar and intergalactic media.
