中国天文学家利用FAST望远镜将重复的快速无线电连发与年轻的超新星残余物联系起来。 Chinese astronomers link repeating fast radio bursts to young supernova remnants using the FAST telescope.

使用FAST射电望远镜的中国天文学家发现有力证据表明,一些快速无线电暴发(FRBs)起源于年轻的超新星残留物。 Chinese astronomers using the FAST radio telescope have found strong evidence that some fast radio bursts (FRBs) originate in young supernova remnants. 通过对FRB 20190520B进行为期四年的监测,他们观察到其分散测量值稳步下降,表明信号通过密集、不断扩大的环境传递。 By monitoring FRB 20190520B for four years, they observed a steady decline in its dispersion measure, indicating the signal travels through a dense, expanding environment. 这表明爆破来自一个年轻的磁铁磁铁 位于一个只有10到100年的超新星残余物中 支持这样的理论 大规模恒星爆炸可以产生重复的FRB This suggests the burst comes from a young magnetar in a supernova remnant only 10 to 100 years old, supporting the theory that massive star explosions can produce repeating FRBs. 该发现刊登在《科学公报》上,标志着在了解FRB起源方面的一大进步,并突出了FAST在长期射电天文学中的关键作用。 The discovery, published in Science Bulletin, marks a major advance in understanding FRB origins and highlights FAST’s critical role in long-term radio astronomy.
