Einstein@Home is a volunteer
distributed computing project that searches through data from the
LIGO detectors for evidence of continuous
gravitational-wave sources, which are expected from objects such as rapidly spinning non-axisymmetric
neutron stars. A sister project examines radio telescope data from the
Arecibo Observatory, searching for radio
pulsars. Running on the
Berkeley Open Infrastructure for Network Computing (BOINC) software platform, Einstein@Home is hosted by the
University of Wisconsin–Milwaukee and the
Max Planck Institute for Gravitational Physics (Albert Einstein Institute, Hannover, Germany). Its director is
Bruce Allen. On August 12, 2010, the first discovery by Einstein@Home of a previously undetected radio pulsar
J2007+2722, found in data from the Arecibo Observatory, was published in
Science. The project had discovered 49 pulsars as of December 2014. Einstein@Home is
