Astronomy and astrophysics are the study of objects and phenomena that are found beyond our solar system. This combines theoretical simulations and observation with both terrestrial and space-craft-borne instruments of the electromagnetic radiation and high-energy particles emitted by celestial bodies.

Linear to circular conversion in the polarized radio emission of a magnetar Radio pulses from a rare, radio-loud magnetar, XTE J1810−197, are seen to have undergone a conversion in their polarization state. This change can be linked to the magnetar’s magnetic field geometry, and has commonalities with an effect also seen in fast radio bursts ..read more

A freely precessing magnetar following an X-ray outburst A radio-loud magnetar, XTE J1810–197, has been observed to precess shortly after an X-ray outburst. The precession decayed over the subsequent few months, which probably rules out freely precessing magnetars as the source of the fast radio bursts ..read more

A model for heating the super-hot corona in solar active regions A state-of-the-art simulation reveals that the long-lasting 10 MK plasma in solar active regions can be heated by magnetic reconnections driven by continuous flux emergence that repeatedly deposit impulsive heating into the coronal plasma ..read more
