Using four radio telescopes, astronomers from the National Astronomical Observatory of Japan and elsewhere have conducted multi-frequency multi-epoch radio observations of a radio-loud magnetar known as XTE J1810-197. Results ...
Like light waves, magnetic waves move through materials at a fixed maximum velocity. However, at the smallest possible length scale (nanometres) and the shortest possible time scale (femtoseconds), magnetism behaves differently. ...
