Low Latency transient search of Gravitational Waves for the Advanced Detectors

The reliability of the first detection is one of the most interesting challenges for the gravitational wave community. To increase the detection confidence, the LIGO and Virgo collaborations have already started coincident observations between gravitational waves detectors and other astronomical instruments, like electromagnetic or neutrino detectors. This can be done in two directions: searching for gravitational waves triggered by the electromagnetic information, or pointing the electromagnetic telescopes to the sky position given in real time by the gravitational wave analysis. The success of the latter case depends strongly on the analysis speed of gravitational wave pipelines to analyze data and extract any gravitational wave candidate with as much information as possible. In this paper we discuss the case of the coherent Waveburst pipeline, the main pipeline used in the past scientific LIGO-Virgo analyses for the search of gravitational wave transients, reporting the capability of making an all-sky and all-time analysis and the analysis speed performance.
