題目:Magnetar Powered Electromagnetic Counterparts of Gravitational Wave
摘要:The successful joint observation of the gravitational wave event GW170817 and its multiwavelength electromagnetic counterparts enabled us to witness a definite merger event of two neutron stars for the first time. The electromagnetic counterparts provide invaluable information on the physics of the merger process. The merger of a neutron star binary may result in the formation of a rapidly spinning magnetar. Prolonged energy injection from a magnetar remnant will produce some potential EM counterparts at different times and at different frequencies. In this talk, I will introduce the properties of EM counterparts driven by magnetar. In addition, I will introduce how to constrain the long-lived remnants of neutron star binary mergers from late-time radio observations of short duration gamma-ray bursts.
