| contents | Compact binary mergers, detected in gravitational waves since 2015, are candidate sources for astrophysical neutrinos in the GeV regime from proton-proton and proton-neutron collisions. This contribution presents the results of the search for such a signal using mergers detected during the fourth observing run of the LIGO, Virgo, and KAGRA interferometers. We use the dense infill array at the center of the IceCube detector, IceCube-DeepCore, to select neutrino candidates in the 0.5-5 GeV energy range. The search for a statistically significant excess associated with an astrophysical signal is performed in a $\pm$ 500 s window around the gravitational wave detection time. We do not observe any statistically significant excess in the neutrino data, and set upper limits on the neutrino emission from these objects. Additionally, we search for subpopulations of neutrino-emitting sources, including merger events detected in previous observing runs; no significant signal has been identified yet. |
