Performance of a thermally deformable mirror for correction of low-order aberrations in laser beams

Abstract The thermally deformable mirror is a device aiming at correcting beam-wavefront distortions for applications where classical mechanical methods are precluded by noise considerations, as in advanced gravitational wave interferometric…

On the background estimation by time slides in a network of gravitational wave detectors.

Abstract: (arXiv) Time shifting the outputs of Gravitational Wave detectors operating in coincidence is a convenient way to estimate the background in a search for short duration signals. This procedure…

EGC: A time-frequency augmented template-based method for gravitational wave burst search in ground-based interferometers.

Abstract: (IOP) The detection of burst-type events in the output of ground gravitational wave detectors is particularly challenging. The potential variety of astrophysical waveforms, as proposed by simulations and analytic…

Reconstruction of source location in a network of gravitational wave interferometric detectors.

Abstract: (arXiv) This paper deals with the reconstruction of the direction of a gravitational wave source using the detection made by a network of interferometric detectors, mainly the LIGO and…
