Dark matter deficient galaxies have lost their dark matter haloes due to interactions during their evolution. In particular, during their fusion history. The existence of these galaxies is a debated subject, both from the observational and theoretical points of view. In this work, we study the population of dark matter deficient galaxies in the hydrodynamical simulation IllustrisTNG, which follow the evolution of dark matter and baryonic matter. We analyse the distribution of these galaxies within the host halo, and how this distribution changes with halo mass, and redshift. The aim of this study is to gather information about how these galaxies are formed, and how their population evolves.
