• Radio Evidence of a Minor Merger in The Shapley Supercluster

  17.01.2022

  A group of astronomers led by the Italian National Institute of Astrophysics with contributions from the Argelander Institute for Astronomy (AIfA) at the University of Bonn has conducted a multi-frequency and multi-band study of the Shapley Supercluster, where the formation of large structures is ongoing at the present cosmological age. Radio astronomers have discovered a radio emission that acts as a "bridge" between a cluster of galaxies and a group of galaxies. The latter recently collided with the cluster like a giant bullet that triggered the emission. The observations, reported in an Astronomy & Astrophysics article, were carried out with the Australian ASKAP radio telescope, the South African MeerKAT radio telescope, and the Indian Giant Metrewave Radio Telescope (GMRT). Optical data collected with ESO's Vlt Survey Telescope (VST) and X-ray data from ESA's XMM-Newton space telescope completed the study.

  The "NRW-Cluster für datenintensive Radioastronomie: Big Bang to Big Data" (B3D) has set itself the task of combining radio astronomy and data science. AIfA is a member and will participate in the next three years in networking the knowledge of radio astronomers, interested data scientists as well as companies from the industry.

  Using the Far Infrared Field-Imaging Line Spectrometer (FIFI-LS), developed by the University of Stuttgart and installed aboard the flying observatory SOFIA, a team led by Frank Bigiel of the Argelander Institute for Astronomy, or AIfA, at the University of Bonn, Germany, has completed a far-infrared map of the spiral galaxy NGC 6946 revealing the distribution of ionized carbon in this galaxy. These data help to estimate the star-formation rate not only in the nearby universe but also in distant galaxies of the early universe.
