Abstract :
Low-frequency, high-time-resolution radio studies have seen a renaissance in the last years not only because of the new generation of large radio telescopes but perhaps even more importantly because modern computing technology is facilitating high-resolution, wide-field observations. I will present ongoing pulsar and fast transient studies with LOFAR and the GBT at frequencies from 10-400 MHz. I will highlight the scientific successes of these studies, including the discovery of the first pulsar in a stellar triple system, as well as new insights into the magnetospheres of radio pulsars. These projects are pushing the envelope of big data in radio astronomy. For example, our LOFAR survey produces 40Gb/s of data, and the > 1Petabyte of data we have already acquired will take many millions of CPU core hours to reduce. These challenges are being successfully tackled, and are setting us on the path to make another big scientific leap with the Square Kilometer Array (SKA), where virtually all such data will have to be processed in real-time.
