Context. The growing amount of integral-field spectroscopic data creates an increased demand for understanding kinematic peculiarities that carry valuable information about the evolution of host galaxies. Aims. For kinematically distinct cores (KDCs), a number of formation mechanisms have been proposed, but it is still unclear as to which of them commonly occur in the Universe. We aim to address the KDC formation in the cosmological context. Methods. We used the publicly available data of the large-scale hydrodynamic cosmological simulation Illustris. We identified 134 KDCs, studied their properties, and followed their evolution back in time. Examples of four galaxies hosting KDCs are presented and described in detail.
