LISA Pathfinder Takes Major Step In Hunt For Gravity Waves
2011-11-14 10:44:11

Sensors destined for ESA´s LISA Pathfinder mission in 2014 have far exceeded expectations, paving the way for a mission to detect one of the most elusive forces permeating through space — gravity waves. The Optical Metrology Subsystem underwent its first full tests under space-like temperature and vacuum conditions using an almost complete version of the spacecraft. The results exceeded the precision required to detect the enigmatic ripples in the fabric of space and time...

Squeezed Laser Will Bring Gravitational Waves To The Light Of Day

  Measuring at the limits of the laws of nature — this is the challenge which researchers repeatedly take up in their search for gravitational waves. The interferometers they use here measure with such sensitivity that a particular quantum phenomenon of light — shot noise — limits the measuring accuracy. With the "squeezed light" method scientists from the Max Planck Society and the Leibniz University Hannover likewise use quantum physics in a countermove in order to...

The final piece of Einstein's jigsaw Direct evidence of the existence of gravitational waves is something that has long eluded researchers, however new research has suggested that adding just one of the proposed detectors in Japan, Australia and India will drastically increase the expected rate of detection. In a study published today, Friday, 27 May, in IOP Publishing's journal Classical and Quantum Gravity, Professor Bernard Schutz, of the Albert Einstein Institute, Germany, demonstrated...

A team of scientists and engineers at NASA's Jet Propulsion Laboratory has brought the world one step closer to "hearing" gravitational waves -- ripples in space and time predicted by Albert Einstein in the early 20th century. The research, performed in a lab at JPL in Pasadena, Calif., tested a system of lasers that would fly aboard the proposed space mission called Laser Interferometer Space Antenna, or LISA. The mission's goal is to detect the subtle, whisper-like signals of gravitational...

An astrophysics experiment in America has demonstrated how fundamental research in one subject area can have a profound effect on work in another as the instruments used for the Laser Interferometer Gravitational-Wave Observatory (LIGO) pave the way for quantum experiments on a macroscopic scale.The work is reported in a research article published today, Thursday, 16 July, in New Journal of Physics (co-owned by the Institute of Physics and German Physical Society). It can be found at...

New information about the heart of one of the most famous objects in the sky -- the Crab Pulsar in the Crab Nebula -- has been revealed by an international team of scientists searching for gravitational waves. The team's achievement also is the first direct look into the interior of a neutron star.The research team detected signals from the pulsar -- a rapidly spinning neutron star -- with the Laser Interferometer Gravitational-Wave Observatory (LIGO). The analysis of the signals reveals that...
