The analysis, led by Nanjing University, revealed a striking 909-Hz quasi-periodic oscillation (QPO) lasting just 160 milliseconds. Both the millisecond magnetar and magnetized jet concepts were proposed by Professor Zhang more than a decade ago. “This discovery transforms our understanding of the most extreme explosions in the cosmos,” Professor Zhang emphasized. “As more advanced space observatories come online, we expect to uncover more of these fleeting signals,” Professor Zhang said. Professors Bin-Bin Zhang (Nanjing University) and Shao-Lin Xiong (CAS) are co-corresponding authors alongside HKU’s Professor Bing Zhang.
