LIGO and Virgo make first detection of gravitational waves produced by colliding neutron stars(图)
LIGO Virgo first detection gravitational waves produced colliding neutron stars
2017/10/26
For the first time, scientists have directly detected gravitational waves -- ripples in space-time -- in addition to light from the spectacular collision of two neutron stars. This marks the first tim...

Gravitational Waves+New Clues From Space Reveal New Way To Make A Black Hole(图)
Gravitational Waves Space Make A Black Hole
2017/10/26
For the first time, scientists worldwide and at Penn State University have detected both gravitational waves and light shooting toward our planet from one massively powerful event in space -- the birt...
Gravitational waves carry information about their origins and about the nature of gravity that cannot otherwise be obtained. Physicists on the LIGO and Virgo teams concluded that, as with LIGO’s first...

Rapid detection of compact binary coalescence with a network of advanced gravitational-wave detectors will offer a unique opportunity for multi-messenger astronomy. Prompt detection alerts for the ast...
Detecting relic gravitational waves in the CMB: A statistical bias
Detecting relic gravitational waves statistical bias
2011/10/13
Analyzing the imprint of relic gravitational waves (RGWs) on the cosmic microwave background (CMB) power spectra provides a way to determine the signal of RGWs. In this Letter, we discuss a statistica...
Are gravitational waves from giant magnetar flares observable?
gravitational giant magnetar observable
2011/10/18
Are giant flares in magnetars viable sources of gravitational radiation? Few theoretical studies have been concerned with this problem, with the small number using either highly idealized models or as...
Towards Quark Deconfinement in Neutron Stars via Spindown: Gravitational Waves or Magnetic Braking?
Quark Deconfinement Neutron Stars Gravitational Waves Magnetic Braking
2011/9/28
A phase of interacting quark matter can arise inside the dense core of isolated neutron stars when they have been sufficiently spun down from their initial rapidly rotating configuration. In this work...
Imprints of the QCD Phase Transition on the Spectrum of Gravitational Waves
the QCD Phase Transition the Spectrum
2011/1/10
We have investigated effects of the QCD phase transition on the relic GW spectrum applying several equations of state for the strongly interacting matter: Besides the bag model, which describes a firs...
Prospects for Direct Detection of Inflationary Gravitational Waves by Next Generation Interferometric Detectors
Direct Detection Inflationary Gravitational Waves Next Generation Interferometric Detectors
2011/1/11
We study the potential impact of detecting the inflationary gravitational wave background by the future space-based gravitational wave detectors, such as DECIGO and BBO. The signal-to-noise ratio of e...
A search for gravitational waves associated with the August 2006 timing glitch of the Vela pulsar
