Observational upper limits on the gravitational wave production of core collapse supernovae
Abstract
The upper limit on the energy density of a stochastic gravitational wave (GW) background obtained from the 2yr science run (S5) of the Laser Interferometer GravitationalWave Observatory (LIGO) is used to constrain the average GW production of core collapse supernovae (ccSNe). We assume that the ccSNe rate tracks the star formation history of the Universe and show that the stochastic background energy density depends only weakly on the assumed average source spectrum. Using the ccSNe rate for z <= 10, we scale the generic source spectrum to obtain an observationbased upper limit on the average GW emission. We show that the mean energy emitted in GWs can be constrained within < (0.491.98)M_{solar}c^{2} depending on the average source spectrum. While these results are higher than the total available gravitational energy in a core collapse event, second and thirdgeneration GW detectors will enable tighter constraints to be set on the GW emission from such systems.
