Parkes observations for project P1083 semester 2021APRS_01

The breakthrough observation of two ultra strong millisecond duration radio pulses temporally coincident with a double-peaked hard X-ray burst from the magnetar SGR 1935+2154 has recently lent strong support to the since long proposed model of a connection among the magnetars and the Fast Radio Bursts (FRBs). \r\nWe are mounting a NAPA program aimed to run a series of "simultaneous" observations in the radio and X-ray bands of both magnetars and ordinary pulsars showing a magnetar-like behavior. The trigger will be suitable X-ray observations allocated after the occurrence of an activation (or reactivation) in the high energy bands of the neutron star underlying the targets. The project will address a range of astrophysical questions, among which: (i) the occurrence of a the link among magnetars and FRBs, (ii) the radio emission mechanisms operating in at least a subset of the magnetar population; (iii) the occurrence (if any) of an evolutionary path connecting the magnetars to the ordinary radio pulsar population

近日，科研人员在磁星（magnetar）SGR 1935+2154的双峰值硬X射线暴中，观测到两束与该暴时域重合的超强毫秒级射电脉冲，这一突破性观测结果为长期以来提出的磁星与快速射电暴（Fast Radio Bursts, FRBs）之间存在关联的模型提供了强有力支撑。
我们正在推进一项NAPA项目，旨在对磁星以及表现出类磁星行为的普通脉冲星开展一系列"协同"射电与X射线波段联合观测。该项目的触发机制为：当目标中子星在高能波段出现活动（或再活动）后，调度合适的X射线观测计划。本项目将解决一系列天体物理学问题，其中包括：(i) 磁星与快速射电暴之间是否存在关联；(ii) 至少部分磁星群体所采用的射电辐射机制；(iii) 磁星与普通射电脉冲星群体之间是否存在演化关联路径（若存在的话）。
