First joint Gravitational Waves search by the Auriga-Explorer-Nautilus-Virgo collaboration

Understand

We present results of the search for coincident burst excitations over a 24 hours long data set collected by AURIGA, EXPLORER, NAUTILUS and Virgo detectors during September 2005.

• The search of candidate triggers was performed independently on each of the data sets from single detectors.
• We looked for two-fold time coincidences between these candidates using an algorithm optimized for a given population of sources and we calculated the efficiency of detection through injections of templated signal waveforms into the streams of data.
• To this purpose we have considered the case of signals shaped as damped sinusoids coming from the galactic center direction.
