 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". Studying the extreme astrophysics of neutron stars, black holes and other exotica is key to understanding fundamental gravitational and particle physics.

-DRAGNET extends LOFAR with a high-speed, wide-angle radio camera mode that is capable of detecting and localizing fast radio transients in real time. +DRAGNET extends LOFAR with a high-speed, wide-angle radio camera mode that is capable of detecting and localizing fast radio transients in real time. We will scan the sky for sub-second bursts coming from previously unpredicted or unobserved astrophysical phenomena, while simultaneously observing hundreds of known radio-emitting neutron stars (pulsars).
