Resumen:
active galactic nuclei is an extensively topic of investigation in the literature. It is known the importance that this object has in its medium where it is formed and ejected, just like its consequences. In the current literature it is widely discussed about the reheating in the intracluster medium in the vicinities of the central and brightest galaxies within the clusters. This mechanism which holds the cooling flow in galaxy clusters is known for its crucial contribution of cavities and bubbles formation which are detected there. Those quasi-spherical regions with low density gas and low emission, but visible through x-ray images are formed by the shock between the jet and the MIA. Since these cavities are formed from the jet material when interacting with the MIA, it means that studying the chemical composition of those cavities allow us to understand the jet nature. The state of art claims that it can be composed by baryonic plasma, electron and positron pairs or heavy ions. In principle it can be checked through x-ray imaging and spectroscopy, taking into account the Iron mass contamination of the intracluster gas, enriched by type Ia and II Supernovae. Previous studies suggest a negative gradient profile of contamination of products originating from type II supernovae in relation to type Ia supernovae by making a radial profile of the cluster, meaning that the outer regions of the cluster show greater contamination of type II supernova products, and the central regions dominance of supernova Ia products. By means of the Iron mass ratio, related to some elements such as Oxygen, Silicon and Sulfur, we identified that the material which composes those cavities and/or bubbles are in majority yields from Supernovae Ia explosion, because this material is included in this region. This analysis was possible given these previous results about the gradient metallicity towards the center, where contains also a Iron mass fraction gradient of metals produced by SNIa. The obtained results here are favored by the material displacement model in the surroundings of the central region of the clusters by the jet. The responsible mechanism for this displacement can be either entrainment of the material around the jet or advection of the material by the work done by the jet.
