Galaxies Lacking Dark Matter: Anomalies or a Natural Outcome of the Standard Model?

In recent years, there has been an increasing number of scientific papers announcing the discovery of galaxies without dark matter. Dark matter is supposed to bind ordinary matter and accelerate the formation of galaxies. Therefore, the existence of galaxies lacking dark matter is difficult to fit into the current paradigm of galaxy formation and evolution. In this talk, I will review some of the best-known examples of dark matter-deficient galaxies and what solutions the scientific community has proposed to explain the mysterious nature of these objects.
