             abstract = "We study the generation of a stochastic gravitational wave (GW) 
                         background produced from a population of core-collapse supernovae, 
                         which form black holes in scenarios of structure formation. In 
                         particular, we take into account in the present paper the history 
                         of star formation derived by Springel \& Hernquist, who employed 
                         hydrodynamic simulations of structure formation in a cold dark 
                         matter (CDM) cosmology. In addition, and contrary to previous 
                         studies, we consider the effect of taking into account different 
                         values of the alpha parameter, the fraction of the progenitor mass 
                         which forms the black hole. Different values of alpha imply 
                         different frequency bands for the GWs produced. Because the 
                         sensitivity of the GW detectors depends on the frequency of the 
                         GWs, it is worth studying the influence of alpha on the detection 
                         of the background considered here. We then study the detectability 
                         of the GW background produced in scenarios such as those studied 
                         here and discuss what astrophysical information could be obtained 
                         from a positive or even negative detection of such a putative 
                         background. In particular, we show that the formation of a 
                         pre-galactic population of black holes could have generated a 
                         stochastic GW background that should be detected in the future by 
                         correlating signals of a pair of advanced LIGO observatories (LIGO 
                         III) at a signal-to-noise ratio greater than unity, if alpha > 
                         0.5.",
