Abstract
We report the observation of gravitational waves from two compact binary
coalescences in LIGO's and Virgo's third observing run with properties
consistent with neutron star-black hole (NSBH) binaries. The two events
are named GW200105\_162426 and GW200115\_042309, abbreviated as GW200105
and GW200115; the first was observed by LIGO Livingston and Virgo and
the second by all three LIGO-Virgo detectors. The source of GW200105 has
component masses 8.9(-1.5)(+1.2) and 1.9(-0.2)(+0.3)M(circle dot),
whereas the source of GW200115 has component masses 5.7(-2.1)(+1.8) and
1.5(-0.3)(+0.7)M(circle dot) (all measurements quoted at the 90\%
credible level). The probability that the secondary's mass is below the
maximal mass of a neutron star is 89\%-96\% and 87\%-98\%, respectively,
for GW200105 and GW200115, with the ranges arising from different
astrophysical assumptions. The source luminosity distances are
280(-110)(+110) and 300(-100)(+150) Mpc, respectively. The magnitude of
the primary spin of GW200105 is less than 0.23 at the 90\% credible
level, and its orientation is unconstrained. For GW200115, the primary
spin has a negative spin projection onto the orbital angular momentum at
88\% probability. We are unable to constrain the spin or tidal
deformation of the secondary component for either event. We infer an
NSBH merger rate density of 45-(+75)(33) Gpc(-3) yr(-1) when assuming
that GW200105 and GW200115 are representative of the NSBH population or
130(-69)(+112) Gpc(-3) yr(-1) under the assumption of a broader
distribution of component masses.
