The latest observations from Insight-HXMT were published online in Nature Astronomy on Feb. 18. Insight-HXMT has discovered the very first X-ray burst associated with a fast radio burst (FRB) and has identified that it originated from soft-gamma repeater (SGR) J1935+2154, which is a magnetar in our Milky Way.

Astronomers spot bizarre, never-before-seen activity from one of the strongest magnets in the universe
Astronomers from the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav) and CSIRO have just observed bizarre, never-seen-before behavior from a radio-loud magnetar—a rare type of neutron star and one of the strongest magnets in the universe.

Astronomers unmask cosmic eruptions in nearby galaxies
A brief burst of high-energy light swept through the solar system on April 15, triggering many space-based instruments, including those aboard NASA and European missions. Now, multiple international science teams conclude that the blast came from a supermagnetized stellar remnant known as a magnetar located in a neighboring galaxy.

This might be the fastest magnetar in the whole galaxy
A rapidly twirling, ultramagnetic 500-year-old infant has been spotted zipping at never-before-seen speeds through the Milky Way. It belongs to a super-rare flavor of super-rare star. Source: https://www.livescience.com/baby-magnetar-pulsar.html
Astronomers find signature of magnetar outbursts in nearby galaxies
Apart from black holes, magnetars may be the most extreme stars in the universe. With a diameter less than the length of Manhattan, they pack more mass than that of our sun, wield the largest magnetic field of any known object—more than 10 trillion times stronger than a refrigerator magnet—and spin on their axes every few seconds.

Observations unveil dynamic magnetosphere of the magnetar Swift J1818.0−1607
Using the Parkes radio telescope, astronomers have investigated a radio-loud magnetar known as Swift J1818.0−1607. Results of these observations, providing more insights into the properties of this magnetar, unveiling its highly active and dynamic magnetosphere. The findings are reported in a paper published November 25 on the arXiv pre-print server. Source: https://phys.org/news/2020-12-unveil-dynamic-magnetosphere-magnetar-swift.html…
Galaxy’s brightest gamma-ray binary system may be powered by a magnetar
A team of researchers led by members of the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) has analyzed previously collected data to infer the true nature of a compact object—found to be a rotating magnetar, a type of neutron star with an extremely strong magnetic field—orbiting within LS 5039, the brightest gamma-ray binary system in the…
X-ray and radio bursts detected from magnetar 1E 1547.0–5408
An international team of astronomers has conducted simultaneous radio and X-ray observations of the magnetar 1E 1547.0–5408 during its period of enhanced activity. In result, new X-ray and radio bursts were detected from this source. The finding is reported in a paper published November 12 on arXiv.org.
