- W3039203450 abstract "We present the first search for gravitational waves from the coalescence of stellar mass and subsolar mass black holes with masses between $20--100text{ }text{ }{M}_{ensuremath{bigodot}}$ and $0.01--1text{ }text{ }{M}_{ensuremath{bigodot}}(10--{10}^{3}text{ }text{ }{M}_{J})$, respectively. The observation of a single subsolar mass black hole would establish the existence of primordial black holes and a possible component of dark matter. We search the $ensuremath{sim}164$ day 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 nondetection, we place a 90% upper limit on the rate of $30--0.01text{ }text{ }{M}_{ensuremath{bigodot}}$ and $30--0.1text{ }text{ }{M}_{ensuremath{bigodot}}$ mergers at $<1.2ifmmodetimeselsetexttimesfi{}{10}^{6}$ and $<1.6ifmmodetimeselsetexttimesfi{}{10}^{4}text{ }text{ }{mathrm{Gpc}}^{ensuremath{-}3}text{ }text{ }{mathrm{yr}}^{ensuremath{-}1}$, 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 ($<{10}^{ensuremath{-}4}text{ }text{ }{mathrm{Gpc}}^{ensuremath{-}3}text{ }text{ }{mathrm{yr}}^{ensuremath{-}1}$). If both black holes are primordial in origin, we constrain the contribution of $1(0.1){M}_{ensuremath{bigodot}}$ black holes to dark matter to $<0.3(3)%$." @default.
