Radiogalaxies are galaxies characterized by intense emission of radio waves, primarily produced by relativistic particles in motion along magnetic field lines (known as synchrotron emission). This radio emission is the result of the activity of a supermassive black hole situated at the center of these galaxies, giving rise to a plasma jet that extends over thousands or even millions of

Typically, planets did not form at the distance from their central stars where we observe them today. In fact, during their early evolution, planets migrate from their initial orbit until the system reaches its final configuration. Planetary migration can be induced by several processes: the interaction between the newborn planets and the protoplanetary disk where they formed, the gravitational interaction
