论文摘要
我们首次介绍了从恒星质量和亚磨性质量黑洞的聚集中搜索引力波，质量在$ 20-100〜 \ Mathrm {M} _ {\ odot} $和$ 0.01-1〜 \ Mathrm {m Mathrm {m} _ {\ odot} _ {\ odot}〜$ 10-10-10^3 $}^3^3 $}} 分别。单极质量黑洞的观察将确定原始黑洞的存在和暗物质的可能组成部分。我们搜索了2015 - 2017年期间Ligo-Hanford和Ligo-Livingston同时观察到2015 - 2017年的$ \ SIM 164 $天公共数据。我们发现没有明显的候选重力波信号。使用此非检测，我们将$ 90 \％$上限放在$ 30-0.01〜 \ Mathrm {M} _ {\ odot} $和$ 30-0.1〜 \ Mathrm {M} _ {\ odot} $合并时，$ <1.2 \ times10^6} $ <1.6} $ <1.2 〜\ Mathrm {gpc}^{ - 3} \ mathrm {yr}^{ - 1} $。如果我们通过直接引力波制动考虑二进制形成，那么只有较轻的黑洞起源于原始的，这种合并将极为罕见（$ <10^{ - 4}〜\ Mathrm {gpc}^{ - 3} { - 3} {-3} \ m atrm {yrm {yr}^yr}^{ - 1} $）。如果两个黑洞的起源都是原始的，我们将$ 1（0.1）〜\ mathrm {m} _ {\ odot} $黑孔的贡献限制为$ <0.3（3）\％$。
We present the first search for gravitational waves from the coalescence of stellar mass and sub-solar mass black holes with masses between $20 - 100~\mathrm{M}_{\odot}$ and $0.01 - 1~\mathrm{M}_{\odot}~($10 - 10^3$~\mathrm{M}_{J})$, respectively. The observation of a single sub-solar mass black hole would establish the existence of primordial black holes and a possible component of dark matter. We search the $\sim 164$ days of public LIGO data from 2015-2017 when LIGO-Hanford and LIGO-Livingston were simultaneously observing. We find no significant candidate gravitational-wave signals. Using this non-detection, we place a $90\%$ upper limit on the rate of $30-0.01~\mathrm{M}_{\odot}$ and $30-0.1~\mathrm{M}_{\odot}$ mergers at $<1.2\times10^{6}$ and $<1.6\times10^{4} ~\mathrm{Gpc}^{-3} \mathrm{yr}^{-1}$, respectively. If we consider binary formation through direct gravitational-wave braking, this kind of merger would be exceedingly rare if only the lighter black hole were primordial in origin ($<10^{-4}~\mathrm{Gpc}^{-3}\mathrm{yr}^{-1}$). If both black holes are primordial in origin, we constrain the contribution of $1 (0.1)~\mathrm{M}_{\odot}$ black holes to dark matter to $< 0.3 (3)\%$.
