  Thermonuclear explosions on neutron stars reveal the speed of their jets

  Relativistic jets observed from transient neutron stars throughout the Universe produce bright flares for minutes after each X-ray burst, helping to determine the role individual system properties have on the speed and revealing the dominant launching mechanism.

  Rapid spin changes around a magnetar fast radio burst

  X-ray observations of two large glitches bracketing a fast radio burst in the active Galactic magnetar SGR 1935+2154 reveal a connection between rapid spin change and radiative behaviours of the magnetar.

  Subsecond periodic radio oscillations in a microquasar

  Two instances of approximately 5-Hz transient periodic oscillation features from the source detected in the 1.05- to 1.45-GHz radio band that occurred in January 2021 and June 2022 are reported.

  A long-period radio transient active for three decades

  The discovery of a long-period radio transient, GPM J1839–10, prompted a search of radio archives, thereby finding that this source has been repeating since at least 1988.

  Interchange reconnection as the source of the fast solar wind within coronal holes

  Measurements of fast solar wind streams from the Parker Solar Probe spacecraft provide strong evidence for the interchange reconnection mechanism being responsible for accelerating the fast solar wind.

  A highly magnetized environment in a pulsar binary system

  The observation of pulsar emission at various orbital phases of a companion star probes the diverse magnetic structure in a binary system, and exhibits varying polarization behavior, akin to that observed in certain fast radio bursts.

  Resolved imaging confirms a radiation belt around an ultracool dwarf

  This study presents high-resolution imaging of the ultracool dwarf LSR J1835 + 3259 at 8.4 GHz, demonstrating that its quiescent radio emission is spatially resolved and traces a double-lobed and axisymmetrical structure with properties consistent with radiation belt observations and modelling.

  Galaxy clusters enveloped by vast volumes of relativistic electrons

  For four galaxy clusters it is shown that the radio halo emission is embedded in a much larger emission that extends over 2–3 Mpc, filling the volume of the clusters.

  Rapid quasi-periodic oscillations in the relativistic jet of BL Lacertae

  Analysis of the optical and γ-ray flux monitoring of the blazar BL Lacertae during its outburst in 2020 shows the existence of quasi-periodic oscillations in the relativistic jet with cycles as short as 13 h.

  A radio transient with unusually slow periodic emission

  Analysis of archival low-frequency radio data from the Murchison Widefield Array reveals a periodic transient with an unusual periodicity of 18.18 min, the source of which is localized to our Galaxy and could be an ultra-long-period magnetar.

  An early transition to magnetic supercriticality in star formation

  An analysis of Zeeman measurements reveals that the reduction of magnetic flux relative to mass, which is necessary for star formation, seems to have occurred earlier than previously thought.

  A highly magnetized and rapidly rotating white dwarf as small as the Moon

  A binary star merger has produced a white dwarf with a spin period of under 7 minutes, a magnetic field of 600 to 900 million gauss and a radius only slightly larger than that of our Moon.

  Jets from MRC 0600-399 bent by magnetic fields in the cluster Abell 3376

  Radio observations of the cluster Abell 3376, combined with numerical modelling, attribute the bent jets associated with the second-brightest galaxy in the cluster to an ordered magnetic field at the discontinuity.
