X-Ray Emission Linked to Milky Way's Rare 44-Minute Transient
Astronomers at ICRAR and partners have identified ASKAP J1832-0911 as a rare long-period transient that emits radio bursts every 44 minutes and, for the first time, X-rays observed by Chandra. This cross-wavelength detection from a source about 15,000 light-years away in the Milky Way provides crucial clues to the origin of LPTs and could point to new physics or revised stellar evolution models, with possible explanations including a magnetar or a magnetized white-dwarf binary. The discovery underscores the value of simultaneous radio and X-ray observations to find more such objects.
