Parkes observations for project P1357 semester 2025APRS_12

MeerKAT has already discovered a number of Galactic transients, which are most likely to be Rotating Radio Transients (RRATs). Previous observations of a few of these sources with the Parkes UWL receiver have proven its utility in follow-up timing observations of MeerKAT discoveries.\n MeerKAT has discovered a few more RRATs in its latest observing cycle and more good quality UWL observations of these sources are required to determine the rotational period and period derivative and also to facilitate the study of their emission properties. Therefore, we request follow-up observations of 5 new sources to achieve this and to further enable spectral and polarization studies of these sources. Given the potential link between RRATs, magnetars, and some fast radio bursts (FRBs) suggested by both observations and theories, this study could reveal more similarities between these different classes of transient sources and significantly advance our understanding of their origins.

MeerKAT望远镜已发现多个银河暂现源，它们极有可能是旋转射电暂现源（Rotating Radio Transients, RRATs）。此前使用帕克斯超宽带（UWL）接收机对其中部分源的观测，已证实其在MeerKAT发现源的后续计时观测中的实用性。
MeerKAT在其最新观测周期中又发现了若干RRATs，需要对这些源进行更多高质量的UWL观测，以确定其自转周期和周期导数，并助力研究其辐射特性。因此，我们申请对5个新源进行后续观测，以实现上述目标，并进一步开展这些源的光谱和偏振研究。鉴于观测和理论均表明RRATs、磁星与部分快速射电暴（fast radio bursts, FRBs）之间存在潜在关联，本研究有望揭示这些不同类型暂现源之间更多的相似性，并显著推进我们对其起源的理解。
