Therefore LIGO Scientific Collaboration researchers from the Albert Einstein Institute, UWM, and the LIGO Laboratory are enlisting the aid of an army of home computer users to analyze the data. Estimates indicate that searching gravitational data with the maximum possible sensitivity would require hundreds of teraflops of computing power or more. This is because the earth's motion as it rotates about its axis and orbits the sun shifts the gravitational wave frequency in a way that depends upon the star's location on the sky. LIGO and GEO600 are now sufficiently sensitive that they might detect these signals if the stars are close enough to earth.įinding such signals in gravitational wave data is computationally intensive. Einstein's theory predicts that if these compact stars are not perfectly spherical, they should continuously emit gravitational waves. The ripples travel through space, carrying information both about their source and about the nature of gravity searches data from the US Laser Interferometer Gravitational wave Observatory (LIGO) and the British/German GEO600 gravitational wave observatory for signals coming from very dense, rapidly rotating compact quark and neutron stars. Longer-lived sources of gravitational waves include rapidly rotating compact stars, and binary systems composed of two orbiting stars. Gravitational waves are ripples in the fabric of space and time produced by violent events in the universe such as black hole collisions and exploding stars (supernovae). It searches for gravitational waves in data collected by US and European gravitational wave detectors.Īlbert Einstein's General Theory of Relativity predicted the existence of gravitational waves in 1916, but only now has technology reached the point that scientists hope to detect them directly. LIGO Laboratory Director Barry Barish of Caltech and Principal Investigator Bruce Allen of the University of Wisconsin-Milwaukee will make the announcement during a press briefing at 11AM, on Saturday, February is a flagship program of the World Year of Physics 2005 celebration of the Centennial of Albert Einstein's miraculous year. The World Community Grid team is set up here in case you're interested.Washington DC, 15 February 2005 - A new, grassroots computing project dubbed which will let anyone with a personal computer contribute to cutting edge astrophysics research, will be officially announced at the annual meeting of the American Association for the Advancement of Science (AAAS) in Washington DC. Details and statistics are available at BOINCStats. We've set up a team in the name of Everything2 Noders at each project we've joined, and many others too. We encourage you to join the Everything2 team at all of your projects. wertperch runs World Community Grid as his main project, and up to ten others as backups. In fact, BOINC personnel recommend running at least two projects, in case the primary project runs out of work. There is a list of BOINC projects by research area for those who want to run more than one project. It supports projects from searching for extraterrestrial intelligence through supporting mathematical research into number theory, to medical research (cancer cures, drug interactions and protein analysis) and environmental research (climate change). Largely it's to gather us together in one place, and possibly to boast about our (or rather, our computers') achievements!īOINC (Berkeley Open Infrastructure for Network Computing) is a project designed to enable computationally demanding scientific research to be carried out by a network of small computers. This group is for anyone who uses BOINC clients (or who wants to use their computer to support research) to share in distributed computing projects. Don't waste those spare CPU cycles - your unused CPU time can do good work for science!ĭownload the BOINC client, then /msg wertperch to join the group
