Using various ground-based facilities worldwide, an international team of astronomers has carried out long-term multi-frequency radio observations of a galactic magnetar known as SGR J1935+2154. Results of the observational ...
Visible and infrared light can carry more data than radio waves, but has always been confined to a hard-wired, fiber-optic cable. Working with Facebook's Connectivity Lab, a Duke research team has now made a major advance ...
