Observations detect a new long-period radio transient associated with supernova remnant G22.7-0.2

Using the DAocheng Radio Telescope (DART), Chinese astronomers have detected a long-period transient event. The newfound transient, which received designation DART J1832-0911, has a period of approximately 44 minutes and is associated with a supernova remnant known as G22.7-0.2. The finding was reported Nov. 24 on the pre-print server arXiv.
