AI中文摘要：
大质量天体物理对象可产生巨大的标量场静态构型。当这样的物体最终形成黑洞时，比如通过核心坍缩超新星，标量场突然失去其源；然后静态构型变为动态并以爆发形式传播出去，即“标量海啸”。这些爆发在宇宙历史中积累，形成一个遗迹随机扩散标量背景，峰值在1 - 10³Hz范围。我们提出这是产生此类背景的新机制，计算其频谱，并与未来实验的灵敏度进行比较。我们展示了这如何将实验对标量质量m_φ≲10⁻¹³eV的灵敏度扩展，比之前考虑的单个瞬态事件可及范围大十个数量级。
英文摘要：
Massive astrophysical objects can source huge static configurations of a scalar field. When such an object ends up forming a black hole, for instance, via a core-collapse supernova, the scalar field loses its source abruptly; then the static configuration becomes dynamical and propagates away in a burst, a "scalar tsunami". These bursts accumulate over cosmological history, forming a relic stochastic diffuse scalar background peaked in the $1-10^3~\text{Hz}$ range. We propose this as a novel mechanism for the generation of such a background, compute its spectrum, and compare it with the sensitivity of future experiments. We show how this extends the experimental sensitivity to scalar masses $m_ϕ\lesssim 10^{-13}~\text{eV}$, ten orders of magnitude larger than those accessible via individual transient events previously considered.
