The recent breakthroughs in numerical relativity have made it possible to generate gravitational wave signals coming from binary systems. The waveforms are extracted using the Newman-Penrose formalism and in particular the Weyl scalar ψ 4 . In order for ψ 4 to contain the physical information on the…
Low mechanical loss materials are needed to further decrease thermal noise in upcoming gravitational wave detectors. We present an analysis of the contribution of Akhieser and thermoelastic damping on the experimental results of resonant mechanical loss measurements. The combination of both processes…
Current interferometric gravitational wave detectors use the combination of quasi-monochromatic, continuous-wave laser light at 1064 nm and fused silica test masses at room temperature. Detectors of the third generation, such as the Einstein-Telescope, will involve a considerable sensitivity increase.…
