摘要:

我们报告的脉冲星J1709 $-$ 4429(也被称为B1706 $-$ 44)在定期监测观测与莫隆格洛天文台综合望远镜(UTMOST)的毛刺事件的检测。这个故障是在定时操作中发现的,在定时操作中,我们经常以每天的节奏观察400多个射电暴,同时搜索旋转射电瞬变、射电暴和FRB。由于分数大小为$Δν/ν\approx 52.4 \times10^{-9}$,这里报告的故障是迄今为止该脉冲星已知的最小故障,证明了使用UTMOST进行高节奏故障搜索的有效性。

英文摘要:

We report the detection of a glitch event in the pulsar J1709$-$4429 (also known as B1706$-$44) during regular monitoring observations with the Molonglo Observatory Synthesis Telescope (UTMOST). The glitch was found during timing operations, in which we regularly observe over 400 pulsars with up to daily cadence, while commensally searching for Rotating Radio Transients, pulsars, and FRBs. With a fractional size of $Δν/ν\approx 52.4 \times10^{-9}$, the glitch reported here is by far the smallest known for this pulsar, attesting to the efficacy of glitch searches with high cadence using UTMOST.
