We report polarization properties for eight narrowband bursts from FRB 121102 that have been re-detected in a high-frequency (4–8 GHz) Breakthrough Listen observation with the Green Bank Telescope, originally taken on 2017 August 26. The bursts were found to exhibit nearly 100% linear polarization, Faraday rotation measures bordering 9.3נ10⁴ rad m⁻², and stable polarization position angles, all of which agree with burst properties previously reported for FRB 121102 at the same epoch. We confirm that these detections are indeed physical bursts with limited spectral occupancies and further support the use of sub-banded search techniques in FRB detection.

我们报告了FRB 121102的八个窄带脉冲串的偏振特性，这些脉冲串最初是在2017年8月26日通过Green Bank望远镜在高频（4-8 GHz）穿透收听观察中检测到的。这些脉冲串显示出法拉第旋转几乎达到100％的线性极化，法拉第旋转测量的边界为9.3 m10 ⁴  rad m ^-2，并且极化位置角稳定，所有这些与先前报道的同一时间FRB 121102的爆发特性一致。我们确认这些检测确实是具有有限频谱占用的物理脉冲，并进一步支持在FRB检测中使用子带搜索技术。
