VLA Searches for Fast Radio Transients at 1 TB/hour
Abstract
Millisecond-scale radio transients (e.g., pulsars) have typically been pursued by single-dish telescopes due to their computational simplicity. However, interferometers have larger fields of view, finer spatial resolution and more interference robustness, opening new possibilities in fast radio transients surveys. We have demonstrated this concept by using the VLA to image the sky with a cadence of 5 ms. This observing mode produces 1 TB/hour in images that we search with a parallelized transient detection pipeline. I will describe science applications of this system, including our pursuit of the newly-discovered population of cosmological radio transients, and our plans to extend it to commensally search all VLA data for fast transients in real time.
