We look at the distribution of black hole masses, black hole spins, and the redshift (cosmological time) of the mergers. Theblack hole massestell us something about how you go from a massive star to a black hole. Thespinstell us something about how the binaries form. The redshift tells ...
The gravitational wave (GW) event GW170817 from a binary neutron star merger together with the electromagnetic counterpart showed that the speed of GWs c t is very close to that of light for the redshift z 0 . 0 0 9 . This places tight constraints on dark energy models constructed in ...
Footnote 2 One should mention that for high-redshift events, such as GW190521, assumption of vector GW polarization can yield substantially smaller mass estimate than general relativity because mass in the source frame becomes sensitive to the luminosity distance. Hence, such events must be excluded...

Its X-ray and host-galaxy properties allow several possible explanations including a short γ-ray burst seen off-axis, a low-luminosity γ-ray burst at high redshift, or a tidal disruption event involving an intermediate-mass black ... YQ Xue,XC Zheng,Y Li,... - 《Nature》 被引量: ...
REDSHIFTIn this paper, our universe is regarded as a codimension-2 brane embedded in a noncompact six-dimensional Anti-de Sitter (AdS) spacetime. We derive the gravitational horizon radius on the brane under the low-energy approximation, which reflects how the extra dimensions cause the short...
galaxies: distances and redshiftsgalaxies: fundamental parametersgalaxies: individual (NGC 4993)The historic detection of gravitational waves from a binary neutron star merger (GW170817) and its electromagnetic counterpart led to the first accurate (sub-arcsecond) localization of a gravitational-wave ...
We use the cosmic microwave background data from Planck and the joint analysis of the BICEP2/Keck Array and Planck, galaxy clustering data from the SDSS LRG survey, BOSS baryon acoustic oscillation data, and redshift space distortion measurements to place constraints on the remaining Horndeski ...
