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.
