Galactic radio sources as a research area focuses on the detection, characterization, and physical interpretation of radio emission originating within a galaxy, typically the Milky Way. It encompasses studies of synchrotron and thermal bremsstrahlung processes in supernova remnants, H II regions, pulsars, molecular clouds, and the interstellar medium, employing radio continuum and spectral line observations (e.g., HI, CO, recombination lines). This field integrates interferometric imaging, polarization measurements, and spectral modeling to constrain magnetic fields, cosmic-ray populations, ionized gas properties, and star-formation-related feedback, thereby elucidating the structure, dynamics, and energetic processes shaping galactic environments.
Using NASA's Fermi space telescope, Italian astronomers have observed a radio source known as 3C 216. As a result, they detected increased gamma-ray activity from this source, including a strong outburst. The finding is reported ...
Using the MeerKAT telescope, astronomers have discovered a new odd radio circle that appears to be associated with an elliptical galaxy known as WISEA J021912.43–050501.8. The finding, which could help us better understand ...
Researchers at the University of Minnesota Twin Cities College of Science and Engineering have developed a new technique that reconstructs two dimensional (2D) radio images–visual representations created from radio waves–into ...
