论文摘要
太阳质质量黑洞的质量在$ \ sim 1-2.5 m _ {\ odot} $范围内不是传统恒星进化的预期，但可以通过捕获小型原始黑洞（PBH）或某些品种粒子粒子粒子的积累而自然产生。我们认为，这种“传输”太阳能BHS的独特签名是它们的质量分布将遵循NSS的分布。这将与传统恒星进化或早期宇宙PBH产生预测的太阳质量范围内的黑洞的质量功能不同。我们提出，在$ \ sim 1-2.5 \，{\ rm m} _ \ odot $的狭窄质量窗口中对太阳能质量BH总体质量分布的分析可以提供对这些BHS起源的简单而强大的测试。二进制合并事件GW190425和GW190814的最近的Ligo/处女座重力波（GW）观察结果与$ \ sim 1.5-2.6〜m _ {\ odot} $的BH质量一致。尽管这些结果激发了人们对暗物质传播的太阳能质量BHS的猜测，但我们证明了这些特定事件的起源不太可能源于NS内爆。来自即将到来的GW观察结果的数据将能够以很高的信心区分太阳能质量BHS和NSS。这种能力将有助于和增强我们提出的测试的功效。
Solar-mass black holes with masses in the range of $\sim 1-2.5 M_{\odot}$ are not expected from conventional stellar evolution, but can be produced naturally via neutron star (NS) implosions induced by capture of small primordial black holes (PBHs) or from accumulation of some varieties of particle dark matter. We argue that a unique signature of such "transmuted" solar-mass BHs is that their mass distribution would follow that of the NSs. This would be distinct from the mass function of black holes in the solar-mass range predicted either by conventional stellar evolution or early Universe PBH production. We propose that analysis of the solar-mass BH population mass distribution in a narrow mass window of $\sim 1-2.5\,{\rm M}_\odot$ can provide a simple yet powerful test of the origin of these BHs. Recent LIGO/VIRGO gravitational wave (GW) observations of the binary merger events GW190425 and GW190814 are consistent with a BH mass in the range $\sim 1.5-2.6~M_{\odot}$. Though these results have fueled speculation on dark matter-transmuted solar-mass BHs, we demonstrate that it is unlikely that the origin of these particular events stems from NS implosions. Data from upcoming GW observations will be able to distinguish between solar-mass BHs and NSs with high confidence. This capability will facilitate and enhance the efficacy of our proposed test.
