ASKAP J1832−0911 emittiert 2 Minuten lange Radio- und Röntgenpulse mit einer Periode von 44 Minuten:
Detection of X-ray Emission from a Bright Long-Period Radio Transient
Here we report the discovery of an extremely bright LPT (10–20 Jy in radio), ASKAPJ1832−0911, which has coincident radio and X-ray emission, both with a 44.2-minute period. The X-ray and radio luminosities are correlated and vary by several orders of magnitude. These properties are unique amongst known Galactic objects and require a new explanation.
We consider a >0.5 Myr old magnetar with a ≳ 10^13 G crustal field, or an extremely magnetised white dwarf in a binary system with a dwarf companion, to be plausible explanations for ASKAP J1832–0911, although both explanations pose significant challenges to formation and emission theories.

Mystery Object in the Milky Way
Astronomers have found X-rays coming from a strange object that releases regular bursts of radio waves, shedding new light on what that object might be.
