About Einstein@HomeEinstein@Home is a World Year of Physics 2005 and an International Year of Astronomy 2009 project. It is supported by the American Physical Society (APS), the US National Science Foundation (NSF), the Max Planck Society (MPG), and a number of international organizations.
Einstein@Home uses your computer's idle time to search for weak astrophysical signals from spinning neutron stars (often called pulsars) using data from the LIGO gravitational-wave detectors, the Arecibo radio telescope, and the Fermi gamma-ray satellite. Einstein@Home volunteers have already discovered about fifty new neutron stars, and we hope to find many more.
Our long-term goal is to make the first direct detections of gravitational-wave emission from spinning neutron stars. Gravitational waves were predicted by Albert Einstein almost a century ago, but have never been directly detected. Such observations would open up a new window on the universe, and usher in a new era in astronomy.
The year 2015 is an exciting one. Five years after the first-generation LIGO detectors were shut down, the upgraded advanced LIGO instruments came online; on September 18'th they began their first 3-month observing run (O1). These advanced detectors can already "see" three to six times as far as initial LIGO, depending upon the source type. Over the coming two years this will increase to a factor of ten, increasing the number of potentially-visible gravitational-wave sources by a factor of a thousand!
