A research team led by Andrea Botteon of Italy's National Institute for Astrophysics has published findings explaining the origin of the cosmic structure nicknamed the Treble Clef. [1] The work appears in the journal Astronomy & Astrophysics. The team used observations from NASA's Chandra X-ray Observatory and the German eROSITA telescope. [2] The telescopes detected diffuse, hot gas at the location of the structure. This confirms the Treble Clef is hosted by a galaxy cluster. [3]
