Parkes observations for project P1378 semester 2025OCTS_03

We propose to observe 2XMM J104608.7-594306 with the Murriyang UWL receiver. This is a known thermally X-ray emitting neutron star in the Carina Nebula, which was recently discovered to show remarkable bursts of coherent radio emission. This is the first of this class of neutron stars to be seen to emit radio pulses. The primary goal of this proposal is to search for more coherent radio bursts from this object, and study their morphology, spectral features and polarization properties. These aims will provide us with crucial insights into the common emission mechanism operating over a wide range of magnetic field strengths and neutron star ages, which will help to understand the physical link between the different classes of neutron stars and their evolutionary pathways.

本申请拟使用穆里扬（Murriyang）UWL接收机对2XMM J104608.7-594306开展观测。该天体是船底座星云（Carina Nebula）中已知的热X射线发射中子星，近期被发现存在显著的相干射电爆发辐射。这是此类中子星中首个被观测到射电脉冲辐射的天体。本观测申请的核心目标是搜寻该天体的更多相干射电爆发事件，并研究其爆发形态、光谱特征与偏振特性。上述研究将为理解跨广泛磁场强度和中子星年龄范围的通用辐射机制提供关键洞见，有助于阐明不同类别中子星之间的物理关联及其演化路径。
