Title : <\/span>Mysterious fast radio bursts and implication from magnetars to their origins

\n<\/span>Abstract :In 2001, the Park observatory detected a mysterious radio spike with milliseconds’
\nduration\u00a0<\/span>from the direction to the Magellanic cloud, which was called “Lorimer Burst” after its
\ndiscoverer. The number of similar radio transients has been gradually and later rapidly
\nincreased, and called “Fast Radio Bursts (FRBs).” The observational characteristics of FRBs
\nindicate the cosmological distance to its unknown sources. Now, the origin or origins of
\nFRBs have been actively studied by many astronomers. In 2020, an FRB event was
\ndiscovered during a bursting activity of a Galactic magnetar SGR 1935+2154. The magnetars
\nare a subgroup of neutron stars with the strongest magnetic field strength of ~1011<\/sup> T on its<\/span>
\nstellar surface. They sometimes exhibit sporadic X-ray and soft gamma-ray burst emission<\/span>
\nreleasing stored magnetic energy. The recently discovered FRB association to SGR<\/span>
\n1935+2154 indicates that magnetars are one promising candidate for FRBs’ origin. At this<\/span>
\ntalk, I will review the story of rapidly developing fields of the FRBs and observational<\/span>
\nimplications from a diversity of neutron stars, especially magnetars, the strongest magnets of<\/span>
\nour Universe.<\/span>
\n<\/span><\/span><\/p>\n

<\/span><\/span><\/p>\n

The colloquium will be held via ZOOM.<\/p>\n
