我们报告了 63 毫秒射电脉冲星 PSR J1105-6107 的发现和后续定时观测。这颗脉冲星很年轻，特征年龄仅为 63 kyr，根据其色散测量，估计与太阳的距离约为 7 kpc。我们认为它可能与附近的超新星遗迹 G290.1-0.8 (MSH 11-61A) 有关；协会要求脉冲星的自行运动为远离残余中心的~22 mas yr-1（相当于~650 km s-1，距离为7 kpc），假设特征年龄是真实年龄。脉冲星的自旋光度为2.5×1036 ergs-1，在所有已知脉冲星自旋光度中名列前1%。鉴于其估计距离，PSR J1105-6107 因此很可能在高能量下可观测到。事实上，它与已知的 CGRO/EGRET 源 2EG J1103-6106 一致；我们考虑了可能的关联并得出结论认为这是有可能的。
We report the discovery and follow-up timing observations of the 63 ms radio pulsar, PSR J1105-6107. The pulsar is young, having a characteristic age of only 63 kyr and, from its dispersion measure, is estimated to be at a distance of ~7 kpc from the Sun. We consider its possible association with the nearby supernova remnant G290.1-0.8 (MSH 11-61A); an association requires that the proper motion of the pulsar be ~22 mas yr-1 (corresponding to ~650 km s-1 for a distance of 7 kpc) directed away from the remnant center, assuming that the characteristic age is the true age. The spin-down luminosity of the pulsar, 2.5 × 1036 ergs s-1, is in the top 1% of all known pulsar spin-down luminosities. Given its estimated distance, PSR J1105-6107 is therefore likely to be observable at high energies. Indeed, it is coincident with the known CGRO/EGRET source 2EG J1103-6106; we consider the possible association and conclude that it is likely.
