Star nurseries interact with their environment
Using NOEMA and the IRAM 30-m telescope, an international team of astronomers from different laboratories, including the Institut d'Astrophysique Spatiale (IAS-Université Paris-Sud/CNRS), the Laboratoire d’astrophysique de Marseille (Aix-Marseille Université/CNRS) and the Astrophysics Department of CEA-IRfu, just witnessed how the sites of the most intense star formation in the early Universe communicate with their surroundings through rapid gas exchange.

Discovery of a giant blob of ionized hydrogen in a galaxy cluster of the distant Universe
An international team led by researchers from the “Service d'Astrophysique / Laboratoire AIM” of CEA-IRFU has discovered a giant nebula of ionized gas in the central region of the distant galaxy cluster CL J1449+0856. Extending over 300,000 light-years, this nebula was detected from an emission line of hydrogen, arising from a gigantic reservoir of warm gas probably ionized by two luminous quasars of the cluster.
