Abstract:
Astrophysical sources of gravitational waves, such as binary neutron star and
black hole mergers or core-collapse supernovae, can drive relativistic
outflows, giving rise to non-thermal high-energy emission. High-energy
neutrinos are signatures of such outflows. The detection of gravitational waves
and high-energy neutrinos from common sources could help establish the
connection between the dynamics of the progenitor and the properties of the
outflow. We searched for associated emission of gravitational waves and
high-energy neutrinos from astrophysical transients with minimal assumptions
using data from Advanced LIGO from its first observing run O1, and data from
the ANTARES and IceCube neutrino observatories from the same time period. We
focused on candidate events whose astrophysical origin could not be determined
from a single messenger. We found no significant coincident candidate, which we
used to constrain the rate density of astrophysical sources dependent on their
gravitational wave and neutrino emission processes.
