论文摘要
奇数无线电圆圈是在〜1 GHz频率下新鉴定出的弥漫性无线电源，具有边缘的近圆形形态，这与超新星残留物非常相似，尽管由于与先前的银河系超新星残留物的物理关联是由于检测到高银河纬度的奇数无线电圈而具有挑战性的。在这里，报道了Lofar 144 MHz图像中新来源的偶然识别，其形态与奇数无线电圆相似。这是第一个以非常低的频率和lofar的方式识别奇数无线电圆圈的标识。
The Odd Radio Circles are newly identified diffuse radio sources at ~1 GHz frequency, with edge-brightened nearly circular morphology, which is remarkably similar to supernova remnants although a physical association with previous population of Galactic supernova remnants is challenging due to detections of the Odd Radio Circles at high Galactic latitudes. Here, a serendipitous identification of a new source in a LOFAR 144 MHz image with similar morphology as that of Odd Radio Circles is reported. This is the first reported identification of an Odd Radio Circle at a very low frequency and with the LOFAR.
