Coherent method for detection of gravitational wave bursts

  title={Coherent method for detection of gravitational wave bursts},
  author={S.Klimenko and I.Yakushin and A.Mercer and G.Mitselmakher},
We describe a coherent network algorithm for detection and reconstruction of gravitational wave bursts. The algorithm works for two and more arbitrarily aligned detectors and can be used for both all-sky and triggered burst searches. We describe the main components of the algorithm, including the timefrequency analysis in a wavelet domain, construction of the likelihood timefrequency maps, and identification and selection of burst events.

Sparse sky grid for the coherent detection of gravitational wave bursts
The gravitational wave detectors currently in operation perform the analysis of their scientific data jointly. Concerning the search for bursting sources, coherent data analysis methods have been
A template-free approach for waveform extraction of gravitational wave events
A general data-driven and template-free method for the extraction of event waveforms in the presence of background noise is developed and the physical time delays between the arrivals of gravitational waves to the detectors are provided.
Detecting and characterizing gravitational waves with minimal assumptions
After many years of preparation and anticipation, we are finally in the era of routine gravitational-wave detection. All of the detected signals so far have come from merging compact objects– either
Data analysis challenges in transient gravitational-wave astronomy
Gravitational waves are radiative solutions of space-time dynamics predicted by Einstein’s theory of General Relativity. A world-wide array of large-scale and highly sensitive interferometric
A Data-Driven Approach for Extraction of Event-Waveform: Application to Gravitational Waves
In the light of the importance of gravitational waves in astronomy, it is essential to perform independent \textit{data analysis} compared to the approach used by the LIGO team. To address this, here
Memory effect or cosmic string? Classifying gravitational-wave bursts with Bayesian inference
A variety of gravitational-wave transient sources can be modeled in the Fourier domain using a power law. This simple power-law model provides a reasonable approximation for gravitational-wave bursts
All-sky search for short gravitational-wave bursts in the first Advanced LIGO run
We present the results from an all-sky search for short-duration gravitational waves in the data of the first run of the Advanced LIGO detectors between September 2015 and January 2016. The search
Gravitational wave astrophysics, data analysis and multimessenger astronomy
The method of multimessenger astronomy where the discovery of electromagnetic counterparts of gravitational wave events can be used to identify sources, understand their nature and obtain much greater science outcomes from each identified event is addressed.
Enhancing the gravitational-wave burst detection confidence in expanded detector networks with the BayesWave pipeline
This paper quantifies network performance as a function of I for BayesWave, a source-agnostic, waveletbased, Bayesian algorithm which distinguishes between true astrophysical signals and instrumental glitches.
Parameter estimation of gravitational-wave data

Multiresolution techniques for the detection of gravitational-wave bursts
This is a methodology paper that aims to describe the techniques for identifying significant events as well as the necessary pre-processing that is required in order to improve their performance and uses simulated LIGO noise to illustrate the methods.
Coherent waveform consistency test for LIGO burst candidates
The burst search in LIGO relies on the coincident detection of transient signals in multiple interferometers. As only minimal assumptions are made about the event waveform or duration, the analysis
Coherent Network Detection of Gravitational Waves: The Redundancy Veto
A network of gravitational wave detectors is called redundant if, given the direction to a source, the strain induced by a gravitational wave in one or more of the detectors can be fully expressed in
On the splitting of classical algorithms in linear prediction theory
It is shown that the Schur algorithm, the lattice algorithm, and the normalized latticegorithm for computing reflection coefficients can be broken down in a similar manner to the classical Levinson algorithm.
