-Studying the extreme astrophysics of neutron stars, black holes and other exotica is key to understanding fundamental gravitational and particle physics. Extreme astrophysical phenomena are fleeting, however, and it is a major observational challenge to detect such fast "transients". 
  
-DRAGNET extends LOFAR with a high-speedwide-angle radio camera mode that is capable of detecting and localizing fast radio transients in real time. +Studying the extreme astrophysics of neutron starsblack holes and other exotica is key to understanding fundamental gravitational and particle physicsExtreme astrophysical phenomena are fleetinghowever, and it is a major observational challenge to detect such fast "transients".
