Towards the birth of gravitational astronomy. I - Number of events expected from gravitational wave detection by interferometry. II - Directivity and number of events in coincidences expected from gravitational wave detection by interferometry
Within the framework of General Relativity, we investigate the possibilities of gravitational wave detection by an array of large optical interferometers. Under general assumptions, the number of gravitational pulses detected per day is estimated. Typical values and orders of magnitude are discussed and allow us to compare different array configurations. This paper is the first of a series the purpose of which is to put forward minimal conditions for the gravitational signal observation to bring an actual contribution to astronomy.
