B4 – Commission B4 Radio Astronomy


The B4 Commission has the aim to bring together scientists and engineers who carry out observational and theoretical research in radio astronomy and who develop and operate the ground and space-based facilities that are used to explore the Universe at radio wavelengths.

The primary purpose of this Commission will be to coordinate the unique role of Radio Astronomy as part of our global multi-wavelength capability in astronomy, taking in consideration the long-term development in this field at the international level. The importance of results obtained in the radio-band (e.g. magnetic fields, atomic and molecular spectral lines) and this multi-wavelength approach implies that Radio Astronomy need to be adequately represented in global multi-wavelength astronomy.
