标题： Noise in pulsar timing arrays

摘要： 为了成功地利用脉冲星计时阵列探测引力波，我们需要全面了解脉冲到达时间噪声的物理起源和统计特性，并识别降低噪声的方法。 本文我们将回顾脉冲星计时预算中的辐射计噪声、相位抖动噪声和定时噪声，并展示各种用于降低这些噪声的努力。 我们将简要讨论北美纳赫兹引力波天文台（NANOGrav）中毫秒脉冲星定时残差的分量和物理原因的整体评估结果。 显示英文摘要

摘要： To successfully detect gravitational waves with pulsar timing arrays, we need to have a comprehensive understanding of the physical origins and statistical characteristics of the noise in pulse arrival times and identify mitigation methods to reduce the noise. In this paper we will review radiometer noise, phase jitter noise and timing noise in the noise budget of pulsar timing and show various efforts used to reduce them. We will briefly discuss the results of an overall assessment of the components and physical causes of the timing residuals for millisecond pulsars in the North American Nanohertz Observatory for Gravitational Waves (NANOGrav).
