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 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...
International Symposium on Gravitational Waves（ISGW2017）
International Symposium Gravitational Waves
2017/3/28
The direct detection of gravitational waves opens a new window to explore our Universe and indicates the coming of a new era of gravitational wave astronomy. In 2015, the KITPC program on “The Ne...
Newly dedicated observatory to search for gravitational waves
Newly dedicated observatory gravitational waves

Seeking to expand how we observe and understand the universe where we live, the National Science Foundation today helped dedicate the Advanced Laser Gravitational Wave Observatories (Advanced LIGO) at...
BICEP2 and Planck joint study: Gravitational waves remain elusive
BICEP2 Planck joint Gravitational waves remain elusive
2015/3/4
A new joint analysis of data from two South Pole-based experiments--the BICEP2 telescope and the Keck Array, both supported by the National Science Foundation--and the European Space Agency's Planck s...
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
gravitational waves glitch of the Vela pulsar
2010/11/16
The physical mechanisms responsible for pulsar timing glitches are thought to excite quasi-normal mode oscillations in their parent neutron star that couple to gravitational wave emission. In August 2...
By combining observations at gamma-ray and radio wavelengths, astronomers have rapidly increased the known number of millisecond pulsars in the Milky Way. The newly discovered pulsars, found using NAS...
