在350兆赫绿岸望远镜漂移扫描巡天中发现旋转射电瞬变

Discoveries of Rotating Radio Transients in the 350 MHz Green Bank Telescope Drift-scan Survey

Chen Karako-Argaman, the GBT Drift-scan Collaboration

摘要:

旋转射电瞬变(RRAT)是一类以无线电发射的零星爆发为特征的脉冲星,这使得它们在典型的基于脉冲星搜索的方法中很难被探测到。使用新开发的后处理技术,自动识别单个明亮的天体物理脉冲,如从RRAT发射的脉冲,我们已经发现了大约30个新的RRAT候选人的数据从绿岸望远镜350兆赫漂移扫描调查。其中6个已经得到确认,其余的看起来非常有希望。在这里,我们描述了这些技术,并提出了这些新的RRAT候选人的最新结果。

英文摘要:

Rotating Radio Transients (RRATs) are a class of pulsars characterized by sporadic bursts of radio emission, which make them difficult to detect in typical periodicity-based pulsar searches. Using newly developed post-processing techniques for automatically identifying single bright astrophysical pulses, such as those emitted from RRATs, we have discovered approximately 30 new RRAT candidates in data from the Green Bank Telescope 350 MHz drift-scan survey. A total of 6 of these have already been confirmed and the remainder look extremely promising. Here we describe these techniques and present the most recent results on these new RRAT candidates.
