Pulse Peak Migration during the Outburst Decay of the Magnetar SGR 1830-0645: Crustal Motion and Magnetospheric Untwisting

George Younes et al.

Summary: This study observes the migration of pulse peak and the change of pulse shape in the magnetar SGR 1830-0645, as well as the shrinking of surface hot spots. The possible causes of these phenomena are suggested to be internal heating and twisted magnetosphere, with a combination of field-line motion and evolving surface radiation beaming.

Long term radio and X-ray evolution of the magnetar Swift J1818.0-1607

K. M. Rajwade et al.

Summary: We report on the long term monitoring campaign of magnetar Swift J1818.0-1607 at radio and X-ray wavelengths over a span of one year. The frequency derivative of the magnetar shows systematic variation and is correlated with the change in the radio emission. The X-ray flux decreases over time and is related to the global change in the magnetosphere of the magnetar.

The dynamic magnetosphere of Swift J1818.0-1607

M. E. Lower et al.

Summary: Radio-loud magnetars, like Swift J1818.0-1607, exhibit significant temporal profile evolution, spectrum inversion, and polarization mode variations, possibly due to ongoing reconfiguration of plasma and electric currents within the magnetosphere. Geometric fits suggest that the magnetar is viewed at an angle of 99 degrees from its spin axis, with a misalignment of approximately 112 degrees between its magnetic and rotation axes. This might indicate that the radio emission from this magnetar originates from magnetic field lines associated with two co-located magnetic poles.

Multi-frequency radio observations of the radio-loud magnetar XTE J1810-197

Sujin Eie et al.

Summary: This study presents multi-frequency multi-epoch radio observations of the magnetar XTE J1810-197, revealing variations in its radio spectra at different frequencies. The pulse width of radio pulsations from the magnetar narrows as the observing frequency increases, and the overall spectrum exhibits a double-peaked feature, providing important insights into emission mechanisms and the surrounding environments of radio magnetars.

Simultaneous 2.25/8.60 GHz observations of the newly discovered magnetar - Swift J1818.0-1607

Zhi-Peng Huang et al.

Summary: Swift J1818.0-1607, discovered in early 2020, is the fifth magnetar known with periodic radio pulsations and the fastest rotating one. Observations revealed decreasing short-term fluctuations and a long-term declining trend in its spin-frequency nu, with a derived characteristic age of about 522 years. The flux density of this magnetar increased at both 2.25 and 8.60 GHz, and its radio spectrum became flatter during the observations.
