【摘要】：旋转射电暂现源是McLauglin等人在2006年采用单脉冲搜寻技术,对Parkes射电望远镜多波束脉冲星巡天数据的处理过程中发现的一类特殊天体。该类天体在绝大多数时间都处于射电宁静状态,偶尔发射特征宽度为毫秒量级的脉冲信号。对其进行长期脉冲到达时间观测发现,其具有类似于脉冲星到达时间特性,但目前还不清楚该天体和脉冲星之间的具体关系。综述了近10年来射电以及其他波段的观测研究和理论模型方面的进展。在射电观测方面,主要介绍观测认证技术(包括零色散滤波、DM搜寻、阈值设定、匹配滤波和效果图检验等)、到达时间以及偏振方面的观测研究进展;在其他波段方面,主要介绍X射线、光学以及近红外波段的观测研究进展。在相关理论模型方面,主要介绍远距离的脉冲星模型,物质与脉冲星磁层相互作用模型以及脉冲星磁层辐射带模型等研究进展。最后将对射电暂现源观测研究进行总结与展望。
[Abstract]:The rotating radio transient source is a special celestial body discovered by McLauglin et al in the course of processing the multi-beam pulsar survey data of Parkes Radio Telescope in 2006 by using monopulse search technique. This kind of celestial body is in the state of radio tranquillity most of the time, and occasionally emits pulse signal with characteristic width of millisecond. It is found that the long term pulse arrival time is similar to that of pulsar, but the relationship between the object and pulsar is not clear. The recent advances in observational studies and theoretical models of radio and other wavebands are reviewed. In the field of radio observation, we mainly introduce the observation authentication technology (including zero dispersion filter DM search, threshold setting, matching filtering and effect diagram checking, etc.), the observation and research progress in arrival time and polarization, and in other wave bands, The progress of X-ray, optical and near-infrared observation is introduced. In terms of theoretical models, the pulsar model, the interaction model between matter and pulsar magnetosphere, and the pulsar magnetospheric radiative zone model are introduced. Finally, the research of radio transient source observation is summarized and prospected.
