A radio-loud magnetar with an identity crisis
Marcus Lower (CSIRO Space & Astronomy)
Abstract: Magnetars are a rare class of highly magnetised neutron star. They are the primary source of local gamma-ray bursts and are speculated to produce a significant fraction of extragalactic fast radio bursts. Studying the local population of magnetars within the Milky Way is therefore key to understanding these highly energetic objects and the role they play in the transient sky. In this talk, I will present the initial results of on-going project to monitor a peculiar radio-loud magnetar, Swift J1818.0-1607, with Murriyang, the Parkes 64-m radio telescope. This includes the unusually pulsar-like properties of this object seen in early observations, and a brief identity crisis in which the neutron star displayed a host of unique behaviour never before seen any other radio pulsar.
