The coalescence of a neutron star with another neutron star or a black hole leads to the formation of a compact binary merger. The upcoming large number of binary merger remnant observations will offer unprecedented opportunities to characterize the population of binary mergers, the physics of these sources, and also the eventual existence of physics beyond the Standard Model. The existence of extra sterile neutrino species is not ruled out because of persistent experimental anomalies and it could have indirect implications on the merger disk cooling rate, the merger outflows, and related electromagnetic observables. In this talk, we will explore the flavor conversion phenomenology in the presence of sterile neutrinos in compact binary merger remnants.
