Some years ago something similar was found in the form of Fermi bubbles; a discovery given the Bruno Rossi Prize. The difference is the frequencies that the structures were found and their size. Fermi bubbles were identified by γ-ray imagining and are far more massive (many thousands of light years in size); both put together makes them far more energetic as well. An interesting part with this discovery is the correspondence between radio and X-ray emissions in this bipolar radio structure. The radio bubbles appear to exactly bound…</p><p><a href="https://hackerpaper.kaipfister.de/p/1909.05534/">Paper and discussion history</a>. A mention is not an endorsement.</p>astro-ph.GA
