Gravitational wave burst search in the Virgo C7 data

Understand

A search for gravitational wave burst events has been performed with the Virgo C7 commissioning run data that have been acquired in September 2005 over five days.

• It focused on un-modeled short duration signals in the frequency range 150 Hz to 2 kHz.
• A search aimed at detecting the GW emission from the merger and ringdown phases of binary black hole coalescences was also carried out.
• An extensive understanding of the data was required to be able to handle a burst search using the output of only one detector.
