An article published in the journal “Nature” reports the results of a study on some fast radio bursts linked to persistent emissions that associates that long duration with a bubble of plasma that generates that radiation. A team of researchers led by the Italian National Institute for Astrophysics registered and studied the fast radio burst with the weakest persistent emission detected so far, cataloged as FRB20201124A, and two other similar events with the VLA radio telescope collecting data that provide evidence of the presence of the plasma bubble at the origin of the radio emissions.
