So, What Is It?
Ultimately, the scientists have not figured out what's causing ASKAP J1832 to feature such changes in its emission intensities. It could be an entirely new version of the objects they've already considered. More observations are needed to pin it down.
Beyond observations with Chandra and SKA, this region of space has also been studied by the SWIFT, the Very Large Array, the Australia Telescope Compact Array, the Giant Metrewave Radio Telescope, MeerKAT, and other facilities. Each of these observations has seen the intensity variations and helped establish baseline timings for the outbursts. For the moment, however, astronomers are still trying to fit what they've seen into models that will help them assign an origin and explanation for the emissions.
