We study the dynamical signatures of black hole (BH) and neutron star (NS) binary mergers via Lidov-Kozai oscillations induced by tertiary companions in hierarchical triple systems. For each type of binary (BH-BH and BH-NS), we explore a wide range of binary/triple parameters that lead to binary mer...
