OREANDA-NEWS. Just a few days after the publication of the article on the first successful finding of the source of a separate fast radio burst FRB 180924, a second such work appeared. In it we are talking about another event FRB 190523, but the rest of the results are very similar — the signal came from a fairly distant and massive galaxy with a moderate rate of star formation, which sharply distinguishes both of these situations from the first (and so far the only) localization of the re-radio burst.

The new work was led by Vikram Ravi (Vikram Ravi) from the California Institute of technology. The team of scientists studied the radio burst FRB 190523, which was recorded on may 23, 2019 by the installation DSA-10 — the initial version of the built array of deep Synoptic Array radio telescopes. The repeated signal was not recorded during the 78 hours of observations during 54 days, distributed about the registration.

One of the main hypotheses proposed to explain fast radio bursts was flashes on magnetars — a subtype of neutron stars with an extremely powerful magnetic field. Such objects should be relatively common in galaxies with a high rate of star formation, as neutron stars are formed from ordinary massive stars as a result of a supernova explosion. This idea was consistent with a re-burst of FRB 121102, which came from a dwarf galaxy where many stars are forming but is not suitable for localized individual stars.
