Abstract

We have witnessed a remarkable advancement in the field of magnetars, neutron stars with extremely strong magnetic fields in recent years. The number of magnetar systems has tripled in less than a decade, and almost all known sources exhibited extraordinary observational characteristics, such as extremely energetic giant flares, various timing anomalies (glitches and anti-glitches), sudden X-ray brightening, etc. The latest two sources appended to the family of magnetars are not shy in disseminating their unique features: 1E 161348-5055 is the longest spin period neutron star system, and PSR J1119-6127 is an energetic rotation powered pulsars. Here, we review some of their unique characteristics; in particular, what binds them to the family of magnetars, which is their energetic bursts.
