They are also developing (with Dr. Kent Wood of NRL) a model that attempts to account for
the radio bursts as a new type of outburst from a class of sources known as «magnetars.»
«It could be created by a superluminous supernova or a long gamma ray burst, and then later on, as it evolves and its rotation slows down a bit, it produces these fast
radio bursts as well as continuous radio emission powered by that spindown.
«When more - powerful detectors provide us with more observations,» Mészáros said, «we also will be able to use Fast
Radio Bursts as a probe of their host galaxies, of the space between galaxies, of the cosmic - web structure of the universe, and as a test of fundamental physics.»
