(first repeating FRB discovered)
FRB121102 was a fast radio burst (FRB) that has since repeated,
i.e., additional FRBs have come from the same direction,
the first such FRB recorded. This has created
much research interest given the opportunities to locate
and study the source and study the repeating FRBs in more
depth. As of 6/2020, hundreds of bursts have been detected
from that location, as well as a persistent radio source,
apparently synchrotron radiation, and
an optical source consisting of a dwarf galaxy
with redshift 0.193.
Also, a 157-day cycle has been discerned, consisting of
some weeks of activity followed by a longer quiescent time.
Theories include some involving
flashes from a neutron star.
