论文摘要

我们提出了使用Meerkat望远镜观察到35个高旋转能量无线电脉冲星。还提出了极化曲线和相关参数。我们得出几何形状,用于选择显示插孔发射的脉冲星。我们指出,在某些情况下,这些无线电脉冲星也应在$γ$ rays中看到,但是需要改进的无线电时间来帮助高能检测。我们讨论了无线电谱的宽度与其高能检测性之间的关系。最后,我们反思旋转能量与无线电极化分数之间的相关性以及对$γ$ ray发射的影响。

We present observations of 35 high spin-down energy radio pulsars using the MeerKAT telescope. Polarisation profiles and associated parameters are also presented. We derive the geometry for a selection of pulsars which show interpulse emission. We point out that, in several cases, these radio pulsars should also be seen in $γ$-rays but that improved radio timing is required to aid the high-energy detection. We discuss the relationship between the width of the radio profile and its high-energy detectability. Finally, we reflect on the correlation between the spin-down energy and the radio polarisation fraction and the implications this may have for $γ$-ray emission.
