A note on the anti-glitch of magnetar SGR 1935+2154
arXiv:2211.01540 · doi:10.1088/1674-4527/acae70
Abstract
The magnetar SGR 1935+2154 is reported to have an anti-glitch, accompanied by fast radio bursts, and transient pulsed radio emission. In the wind braking model, this triplet event tells people that (1) SGR 1935+2154 does not have a strong particle wind and can be approximated by magnetic dipole braking in the persistent state; (2) Its anti-glitch is due to an enhanced particle wind, similar to the first anti-glitch in magnetars; (3) Its transient pulsed radio emission may be due to a decreasing emission beam during the outburst; (4) The enhanced particle acceleration potential and pulsar death line may not be the dominate factor.
