Scientific paper

Data available in the Kraan-Korteweg catalog of 2810 nearby galaxies is used to evaluate the expected rate of supernovae (SN) events according to distance. Three different statistics and two virgocentric flow models for determinating distance of galaxies are used in the evaluation. The results permit calculation of the Expected SN Event Rate (ESNER) according to the sensitivity of a resonant antenna for gravitational radiation detection, considering both an optimistic and a pessimistic theory for the energy converted into gravitational waves during a SN collapse. It is shown that values of the ESNER greater than 1 SN/year can be considered for the ultralow temperature gravitational wave anenna now being constructed by the Rome and Stanford groups, even with pessimistic predictions of the energy emitted as gravitational waves and of the rate of SN explosion.
