Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Eccentricity sheds light on gravitational-wave dark sirens in the mid-band
偏心率 中频带 引力波 暗警报器
2023/5/9
The source localization and distance inference of gravitational waves (GWs) are two crucial factors for GW standard sirens as precise probes of cosmology, astrophysics, and fundamental physics. In thi...
The National Science Foundation (NSF) has renewed a Physics Frontiers Center grant to the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) consortium, giving Cornell astronomy r...
LIGO detects gravitational waves for third time
LIGO detects gravitational waves third time
2017/7/21
The collision of a pair of colossal, stellar-mass black holes has made itself heard, nearly 3 billion light years away, through a cosmic microphone on Earth.
On Jan. 4, the Laser Interferometry Gravi...

Statement from National Science Foundation Director France Córdova regarding news that, after a series of upgrades, researchers have reactivated the twin detectors of the Laser Interferometer Gravitat...
Gravitational waves detected from second pair of colliding black holes
Gravitational waves second pair colliding black holes
2016/6/22
On Dec. 26, 2015 at 03:38:53 UTC, scientists observed gravitational waves -- ripples in the fabric of spacetime -- for the second time.
The gravitational waves were detected by both of the twinLaser ...
Quantum gravitational corrections to the nonrelativistic scattering potential of two masses
General theory of relativity the scattering matrix the order of lap lap
2014/12/20
We treat general relativity as an effective field theory, obtaining the full nonanalytic component of the scattering matrix potential to one-loop order. The lowest order vertex rules for the resulting...
Conserved gravitational charges from Yano tensors
Yano tensor time and space conservation of gravity
2014/12/20
The defining properties of Yano tensors naturally generalize those of Killing vectors to anti-symmetric tensor fields of arbitrary rank. We show how the Yano tensors of flat spacetime can be used to c...
Spin Effects in Long Range Gravitational Scattering
Gravity scattering particles gravity the scattering amplitude quantum
2014/12/19
We study the gravitational scattering of massive particles with and without spin in the effective theory of gravity at one loop level. Our focus is on long distance effects arising from nonanalytic co...
Long Distance Effects in Mixed Electromagnetic-Gravitational Scattering
Scattering dispersed particles the spin configurations
2014/12/19
Using the methods of effective field theory we examine long range effects in mixed electromagnetic-gravitational scattering. Recent calculations which have yielded differing results for such effects a...
Scientists have shown how gravitational waves—invisible ripples in the fabric of space and time that propagate through the universe—might be “seen” by looking at the stars. The new model, developed in...
Characterisation of Low Frequency Gravitational Waves from Dual RF Coaxial-Cable Detector: Fractal Textured Dynamical 3-Space
Low Frequency Gravitational Waves Dual RF Coaxial-Cable Detector Fractal Textured Dynamical 3-Space
2012/5/17
Experiments have revealed that the Fresnel drag effect is not present in RF coaxial cables, contrary to a previous report. This enables a very sensitive, robust and compact detector, that is 1st order...
