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
TLDR
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…

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
TLDR
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.
