我们研究了产生的随机引力波（GW）的背景产生的人口的核心坍缩超新星，形成黑洞的情况下，由Springel和Hernquist，谁采用流体动力学模拟的结构形成的ACDM宇宙学。此外，与以前的研究相比，我们考虑的影响，考虑到不同的值的参数，形成黑洞的祖质量的分数。然后，我们研究了这个GW背景的可探测性，并讨论了什么样的天体物理信息可以从一个积极的，甚至是消极的检测这样一个假定的背景。
We study the generation of a stochastic gravitational wave (GW) background produced from a population of core-collapse supernovae, which form black holes in a scenario by Springel and Hernquist, who employed hydrodynamic simulations of structure formation in a ACDM cosmology. In addition, and in contrast to previous studies, we consider the effect of taking into account different values of the a parameter, the fraction of the progenitor mass which forms the black hole. We then study the detectability of this GW background and discuss what astrophysical information could be obtained from a positive, or even a negative detection of such a putative background.
