The detection of gravitational waves from compact binaries relies on a computationally burdensome processing of gravitational-wave detector data. The parameter space of compact-binary-coalescence gravitational waves is large and optimal detection strategies often require nearly redundant calculations. Previously, it has been shown that singular value decomposition of search filters removes redundancy. Here we will demonstrate the use of singular value decomposition for a composite detection…

Toward Early-warning Detection of Gravitational Waves from Compact Binary Coalescence
Rapid detection of compact binary coalescence (CBC) with a network of advanced gravitational-wave detectors will offer a unique opportunity for multi-messenger astronomy. Prompt detection alerts for
Searching for gravitational waves from binary coalescence
The implementation of a search for gravitational waves from compact binary coalescences in LIGO and Virgo data is described and it is demonstrated that the signal consistency tests are capable of mitigating the effect of non-Gaussian noise and providing a sensitivity comparable to that achieved in Gaussian noise.
Towards low-latency real-time detection of gravitational waves from compact binary coalescences in the era of advanced detectors
Electromagnetic (EM) follow-up observations of gravitational wave events will help shed light on the nature of the sources, and more can be learned if the EM follow-ups can start as soon as the
Parameter estimation for binary neutron-star coalescences with realistic noise during the Advanced LIGO era
Advanced ground-based gravitational-wave (GW) detectors begin operation imminently. Their intended goal is not only to make the first direct detection of GWs, but also to make inferences about the

Use of Singular-Value Decomposition in Gravitational-Wave Data Analysis
Singular-value decomposition is a powerful technique that has been used in the analysis of matrices in many fields. In this paper, we summarize how it has been applied to the analysis of
GPU-accelerated low-latency real-time searches for gravitational waves from compact binary coalescence
The result indicates that it is possible to conduct a full search for GWs from compact binary coalescence in real time with only one desktop computer equipped with a Fermi GPU card for the initial LIGO detectors which in the past required more than 100 CPUs.
Reduced Basis representations of multi-mode black hole ringdown gravitational waves
We construct compact and high accuracy Reduced Basis (RB) representations of single and multiple quasinormal modes (QNMs). The RB method determines a hierarchical and relatively small set of the most
Multimessenger Astronomy: Modeling Gravitational and Electromagnetic Radiations from a Stellar Binary System
Our Sun is one of roughly 100 billion other stars that make up the Milky Way Galaxy. Two-thirds of all stars are paired off, with a gravitational bond between the two stars. Such systems are known as


Extraction of signals from noise
This book is devoted to problems involving extraction of signals from a background of random noise, and takes into account both "white noise" and "correlated noise", which makes its treatment more general, and even simplifies it.
