  We study the influence of the proximity-induced pairing on electronic version
of the Dicke effect in a heterostructure, comprising three quantum dots
vertically coupled between the metallic and superconducting leads. We discuss a
feasible experimental procedure for detecting the narrow/broad
(subradiant/superradiant) contributions by means of the subgap Andreev
spectroscopy. In the Kondo regime and for small energy level detuning the Dicke
effect is manifested in the differential conductance.
