Advanced VIRGO: detector optimization for gravitational waves by inspiralling binaries
An advanced European detector is currently considered. A strong R&D program will be necessary to improve the actual sensitivity of VIRGO and GEO. Naturally such effort must aim to optimize detection, given limited budget and manpower. Among sources, coalescing binaries appear among the most interesting and known. Thus, improvements in signal to noise ratio (S/N) by noise abatement in VIRGO, for...
متن کاملVIRGO detector optimisation for gravitational waves by inspiralling binaries
For future configurations, we study the relation between the abatement of the noise sources and the Signal to Noise Ratio (SNR) for coalescing binaries. Our aim is not the proposition of a new design, but an indication of where in the bandwidth or for which noise source, a noise reduction would be most efficient. We take VIRGO as the reference for our considerations, solely applicable to the in...
متن کاملModelling Gravitational Waves from Inspiralling Compact Binaries
Gravitational waves from inspiralling compact binaries can be reliably extracted from a noisy detector output only if the template used in the detection is a faithful representation of the true signal. In this article we suggest a new approach to constructing faithful signal models.
متن کاملGravitational Waves from Inspiralling Compact Binaries
Inspiralling compact binaries are the most promising sources for gravitational wave detectors like LIGO and VIRGO. For detection one needs to know the gravitational waveform to accuracies much beyond quadrupole approximation. This requires a solution of the generation problem and radiation reaction problem in general relativity. This talk presents a broad brush overview of the techniques used t...
متن کاملGravitational waves from inspiralling compact binaries with magnetic dipole moments
We investigate the effects of the magnetic dipole-dipole coupling and the electromagnetic radiation on the frequency evolution of gravitational waves from inspiralling binary neutron stars with magnetic dipole moments. This study is motivated by the discovery of the superstrongly magnetized neutron stars, i.e., magnetar. We derive the contributions of the magnetic fields to the accumulated cycl...
