"Puzzling Radio Signals: Unexplained Behavior of a Reawakened Magnetar"
TL;DR Summary
A magnetar, XTE J1810-197, emitted strange, wobbly radio signals after "waking up" in 2018, puzzling scientists. These signals cannot be explained by known magnetar behavior, suggesting new processes are at play. Researchers believe a region of undulating plasma near the magnetar's magnetic poles acted as a "polarizing filter," wobbling the radio pulses. They aim to study other radio-emitting magnetars to solve the mystery and gain insights into neutron star formation and high-density matter behavior.
