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.

Testing strong gravity with gravitational waves and Love numbers [PDF]

open access: yes, 2017
The LIGO observation of GW150914 has inaugurated the gravitational-wave astronomy era and the possibility of testing gravity in extreme regimes. While distorted black holes are the most convincing sources of gravitational waves, similar signals might be ...

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 ...

LISA Sources in Globular Clusters [PDF]

open access: yes, 2000
Globular clusters house a population of compact binaries that will be interesting gravitational wave sources for LISA. We provide estimates for the numbers of sources of several categories and discuss the sensitivity of LISA to detecting these sources ...

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.

Quantum metrology for gravitational wave astronomy [PDF]

open access: yesNature Communications, 2010
Einstein's general theory of relativity predicts that accelerating mass distributions produce gravitational radiation, analogous to electromagnetic radiation from accelerating charges. These gravitational waves (GWs) have not been directly detected to date, but are expected to open a new window to the Universe once the detectors, kilometre-scale laser ...

Triangulation of gravitational wave sources with a network of detectors [PDF]

open access: yes, 2009
There is significant benefit to be gained by pursuing multi-messenger astronomy with gravitational wave and electromagnetic observations. In order to undertake electromagnetic follow-ups of gravitational wave signals, it will be necessary to accurately ...
