论文摘要
我们计算出原始黑洞的早期统治时代，从密度扰动产生的重力波背景。黑洞的形成需要扰动线性状态。这种扰动的空间在不对称形成Zel'Dovich煎饼之前达到了最大膨胀，根据参数可以导致黑洞或病毒化的光晕。在这两个情况下，由于崩溃物质的不对称性，四极力矩会产生引力波，这些引力波留下以随机背景的形式留下印记，可以通过不久的将来的重力干涉仪检测到。
We calculate the gravitational wave background produced from density perturbations in an early matter domination era where primordial black holes form. The formation of black holes requires perturbations out of the linear regime. Space with such perturbations reach a maximum expansion before it collapses asymmetrically forming a Zel'dovich pancake which depending on the parameters can either lead to a black hole or a virialized halo. In both cases and due to the asymmetry of the collapsing matter, a quadrupole moment generates gravitational waves which leave an imprint in the form of a stochastic background that can be detectable by near future gravitational interferometers.
