No tension between assembly models of super massive black hole binaries and pulsar observations

open access: yesNature Communications, 2018
Pulsar timing arrays enable the search for the isotropic gravitational-wave (GW) background originating from super massive black hole binary populations, but impose a stringent upper limit on the GW characteristic amplitude.

Gravitational wave astronomy: needle in a haystack [PDF]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2013
A worldwide array of highly sensitive ground-based interferometers stands poised to usher in a new era in astronomy with the first direct detection of gravitational waves. The data from these instruments will provide a unique perspective on extreme astrophysical objects, such as neutron stars and black holes, and will allow us to test Einstein’s theory

Swift/UVOT: 18 Years of Long GRB Discoveries and Advances

open access: yesUniverse, 2023
The Neil Gehrels Swift Observatory (Swift) has been in operation for 18 years. The Ultra-Violet/Optical Telescope (UVOT) onboard Swift was designed to capture the earliest optical/UV emission from gamma-ray bursts (GRBs), spanning the first few minutes ...

GRAVITATIONAL WAVE ASTRONOMY [PDF]

open access: yesAnnual Review of Nuclear and Particle Science, 2004
▪ Abstract  The existence of gravitational radiation is a direct prediction of Einstein's theory of general relativity, published in 1916. The observation of gravitational radiation will open a new astronomical window on the universe, allowing the study of dynamic strong-field gravity, as well as many other astrophysical objects and processes ...

3D characterization of low optical absorption structures in large crystalline sapphire substrates for gravitational wave detectors

open access: yesScientific Reports, 2021
Very high-quality sapphire substrates are key elements of the cryogenic Japanese gravitational interferometer KAGRA, in which they are used to build the main mirrors, working as the test masses to sense the gravitational waves.

The Next Generation Global Gravitational Wave Observatory: The Science Book

open access: yes, 2021
The next generation of ground-based gravitational-wave detectors will observe coalescences of black holes and neutron stars throughout the cosmos, thousands of them with exceptional fidelity. The Science Book is the result of a 3-year effort to study the

Gravitational wave astronomy with TianQin

open access: yesReports on Progress in Physics
Abstract The opening of the gravitational wave window has significantly enhanced our capacity to explore the Universe’s most extreme and dynamic sector. In the mHz frequency range, a diverse range of compact objects, from the most massive black holes at the farthest reaches of the Universe to the lightest white dwarfs in our cosmic ...

Attitude-Orbit Coupled Control of Gravitational Wave Detection Spacecraft with Communication Delays

open access: yesSensors, 2023
In order to meet the position and attitude requirements of spacecrafts and test masses for gravitational-wave detection missions, the attitude-orbit coordination control of multiple spacecrafts and test masses is studied.
