Radio properties of the magnetar near Sagittarius A* from observations with the Australia Telescope Compact Array

Radio properties of the magnetar near Sagittarius A* from observations with the Australia Telescope Compact Array

We have carried out observations of the newly-discovered magnetar in the direction of Sagittarius A* using the Australia Telescope Compact Array in four frequency bands from 4.5 to 20 GHz. Radio pulsations are clearly detected at all frequencies. We measure the pulsar's dispersion measure to be 1650 +/- 50 pc/cm^3, …
