论文摘要
更深，更宽，更快的（DWF）程序在电磁频谱上与望远镜进行观测，从而在毫秒到几天的时间尺度上寻找瞬变。第十dWF观察跑步是在2021年9月的接近实时进行的，由NGC 6744 Galaxy组的连续六天组成，其中包含澳大利亚平方千 /阵列途径摄像机，黑暗X级调制电台和公园台64444的REACTER快速爆发FRB190711的田地。在这项工作中，我们介绍了图像域搜索对瞬态，可变和循环极化源的结果，并在运行之前和之后进行了测试观测和后续观测，并使用观察到的数据以及测试观察结果以及测试观察结果。我们确定了八个可变的无线电源，其中一个由一个脉冲星，六个恒星系统（其中五个显示圆极化的发射）和一个以前未经战役的来源组成。特别令人感兴趣的是从Ultra-Cool Dwarf SCR J1845-6357中检测脉冲，其周期为$ 14.2 \ pm 0.3 $ H 0.3 $ H，与已知的光学旋转期非常吻合，这使其成为发现最慢的旋转旋转的Rotod-Loud-loud Ultra Ultra-fool。
The Deeper, Wider, Faster (DWF) program coordinates observations with telescopes across the electromagnetic spectrum, searching for transients on timescales of milliseconds to days. The tenth DWF observing run was carried out in near real-time during September 2021 and consisted of six consecutive days of observations of the NGC 6744 galaxy group and a field containing the repeating fast radio burst FRB190711 with the Australian Square Kilometre Array Pathfinder, the Dark Energy Camera, the Hard X-ray Modulation Telescope and the Parkes 64m "Murriyang" radio telescope. In this work we present the results of an image-domain search for transient, variable and circularly polarised sources carried out with ASKAP using data from the observing run, along with test observations prior to the run and follow-up observations carried out during and after the run. We identified eight variable radio sources, consisting of one pulsar, six stellar systems (five of which exhibit circularly polarised emission) and one previously uncatalogued source. Of particular interest is the detection of pulses from the ultra-cool dwarf SCR J1845-6357 with a period of $14.2\pm 0.3$ h, in good agreement with the known optical rotation period, making this the slowest rotating radio-loud ultra-cool dwarf discovered.
