There is a massive amount of literature that simply categorizes radio emission in other galaxies in an either/or sense.” ![]() “For decades, astronomers thought there were basically two kinds of radio source that we could see in other galaxies: accreting supermassive black holes and star formation activity. “I am very excited about the implications for having a new class of source out there in the universe,” said Law. To that end, China’s Five-hundred-meter Aperture Spherical radio Telescope (FAST), the largest single-dish telescope on Earth and the facility that spotted FRB 190520, is likely to find many more of these enigmatic bursts in the future. However, we will need to find more of these rare bursts to better understand the mechanisms that produce them, and unravel the full story of FRBs as a whole. Law and his colleagues, who were led by Li Di of the National Astronomical Observatories of the Chinese Academy of Sciences, suggest that FRB 190520 and FRB 121102 might be baby neutron stars that are still surrounded in the messy detritus of the supernovae that made them. ![]() Though FRB 190520 and FRB 121102 seem to erupt at random times, other repeating bursts flash in clear periodic cycles. A handful of sources display repeated bursts, including the newly discovered FRB 190520 and its earlier doppelgänger, FRB 121102. Scientists have found about three dozen FRBs, most of which emit one quick blast of radio light before seemingly disappearing forever. “Now we actually need to explain this double mystery and why FRBs and persistent radio sources are found together sometimes,” he added. Our new discovery is the second FRB with a persistent counterpart (known as FRB 190520), which confirms that the first such example was not a fluke.” “Some thought the first FRB was associated with a radio source by coincidence with some unrelated object in the same galaxy as the FRB. “There are many ideas for what causes FRBs, but the association with a persistent radio source is very helpful in developing and testing models,” Law said in an email. Casey Law, a staff scientist at Caltech who co-authored the new study, said the discovery of the new burst was “a big surprise” because it was such a “a perfect ‘twin’” to another repeating burst, first spotted in 2012, that is also next to a persistent radio source. ![]()
