Astronomy is being transformed by surveys performed with instruments capable of searching the sky for multi-messenger signals with high speed and sensitivity, while delivering science-read datasets to the community. While radio astronomy is not yet fully participating in this revolution, an instrument following the same philosophy that would finally open the dynamic radio sky for exploration is not only urgent but inevitable.
ARGOS is a concept (TRL2) for a leading-edge, low-cost, sustainable “small-D, big-N” radio interferometer, that will realize this ambition, directly addressing multiple fundamental scientific questions, from the nature of dark matter and dark energy to the origin of fast radio bursts. The project, which funded by the European Commission, is led by Dr. John Antoniadis and is a collaborative effort of IA-FORTH, ICS-FORTH and the Univ. of Piraeus in Greece, CEA Saclay in France and the Max-Planck-Institute for Radio Astronomy in Bonn, Germany.
