Measuring a cosmological distance-redshift relationship using only gravitational wave observations of binary neutron star coalescences
neutron stars gravitational waves cosmology
2011/10/14
Detection of gravitational waves from the inspiral phase of binary neutron star coalescence will allow us to measure the effects of the tidal coupling in such systems. These effects will be measurable...
Nature's Most Precise Clocks May Make "Galactic GPS" Possible; Pulsing Pulsars Help in Search for Gravitational Waves
Nature's Most Precise Clocks Galactic GPS Pulsing Pulsars Gravitational Waves
2010/1/11
Radio astronomers have uncovered 17 millisecond pulsars in our galaxy by studying unknown high-energy sources detected by NASA's Fermi Gamma-ray Space Telescope. The astronomers made the discovery in ...
