Extended hierarchical search (EHS) algorithm for detection of gravitational waves from inspiralling compact binaries
Pattern matching techniques such as matched filtering will be used for online extraction of gravitational wave signals buried inside detector noise. This involves cross correlating the detector output with hundreds of thousands of templates spanning a multi-dimensional parameter space, which is very expensive computationally. A faster implementation algorithm was devised by Mohanty and Dhurandh...
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...
متن کاملA template bank to search for gravitational waves from inspiralling compact binaries
Matched filtering is used to search for gravitational waves emitted by inspiralling compact binaries in data from ground-based interferometers. One of the key aspects of the detection process is the deployment of a set of templates, also called a template bank, to cover the astrophysically interesting region of the parameter space. In a companion paper, we described the template bank algorithm ...
