"Einstein@Home currently processes PALFA Mock spectrometer data from Arecibo Observatory. This search run is called "BRP4" (short for Binary Radio Pulsar search #4). It uses the computing power donated by volunteers from all over the world to search the Arecibo data for radio pulsars in binary orbits. Thanks to the enormous amount of donated computing power Einstein@Home conducts the search with the highest sensitivity to pulsars in very tight binary systems. This page lists the detections of known and new pulsars identified from this processing. In the tables below you'll find information for each pulsar."
"Einstein@Home uses your computer's idle time to search for weak astrophysical signals from spinning neutron stars (also called pulsars) using data from the LIGO gravitational-wave detectors, the Arecibo radio telescope, and the Fermi gamma-ray satellite."
