The Early Gaia Data Release 3 (EDR3) provides precise astrometry for nearly 1.5 billion sources across the entire sky. A few tens of these are associated with neutron stars in the Milky Way and Magellanic Clouds. Here, we report on a search for EDR3 counterparts to known rotation-powered pulsars using the method outlined in Antoniadis. A cross-correlation between EDR3 and the ATNF pulsar catalog identifies 41 close astrometric pairs (≲05 at the reference epoch of the pulsar position). Twenty six of these are related to previously known optical counterparts, while the rest are candidate pairs that require further follow-up. Highlights include the Crab Pulsar (PSR B0531+21), for which EDR3 yields a distance of kpc (or kpc taking into account the dispersion-measure prior; errors indicate 95% confidence limits) and PSR 1638−4608, a pulsar thus-far considered to be isolated that lies within 0056 of a Gaia source.

Early Gaia Data Release 3 (EDR3) 为整个天空中近 15 亿个源提供精确的天体测量。其中几十个与银河系和麦哲伦云中的中子星有关。在这里，我们报告了使用 Antoniadis 中概述的方法搜索已知旋转动力脉冲星的 EDR3 对应物。EDR3 和 ATNF 脉冲星目录之间的互相关确定了 41 个紧密的天体测量对（在脉冲星位置的参考纪元处≲05）。其中 26 个与先前已知的光学对应物有关，其余的是需要进一步跟进的候选对。亮点包括 Crab Pulsar (PSR B0531+21)，EDR3 产生的距离为kpc（或kpc 考虑到分散测量先验；错误表示 95% 的置信限）和 PSR 1638-4608，迄今为止被认为是孤立的脉冲星，位于 Gaia 源的 0056 范围内。
