Expected supernovae rates and the detection of gravitational waves.
Abstract
Data available in the Kraan-Korteweg catalog of 2810 nearby galaxies are used to evaluate the expected rate of SNe events vs. distance. Three different statistics and two virgo-centric flow models for determinating distances of galaxies are used in the evaluation. The results permit to obtain the Expected SNe Event Rate (ESNER) vs. the sensitivity of an antenna for gravitational radiation detection. It is shown that values of the Expected SNe Event Rates greater than 1 SN/year can be considered for the ultralow temperature resonant antennas now in construction and for the long baseline interferometers currently under development, on the base of realistic predictions of the energy emitted as gravitational waves in a SN explosion.
