Special Issue Information

Dear Colleagues,

The science of galaxy clusters is entering a new era. Upcoming X-ray missions promise to provide important clues on galaxy cluster physics, from the chemical evolution of the intracluster medium to the non-thermal motions prevalent therein. The former will shed light on the origin of various elements, be it SNe Ia or SNcc, while the latter will test models of AGN feedback and will assess any biases that may enter the cosmological utility of galaxy clusters. Furthermore, upcoming radio projects will shed light on the high-energy particle content of clusters, as well as on the role of the magnetic fields that permeat their atmospheres.

This Special Issue invites observational and theoretical papers in anticipation and in support of these upcoming developments, including on atomic data that will maximize the spectroscopic value of upcoming X-ray missions.

The analysis of the orientation of galaxies is one of the most widely used tools in the fields of extragalactic astronomy and cosmology, enabling the verification of structure formation scenarios in the universe. It is based on the statistical analysis of the distribution of angles, giving the spatial orientation of galaxies in space. In order to obtain the correct analysis results, one is obliged to take into account the Holmberg effect and the fact that galaxies are oblate spheroids, with the real axis ratio depending on the morphological type. However, most of the astronomical data available today do not contain information about the morphological types of galaxies. The analysis of sufficiently numerous observational data allows one to calculate the estimated frequency of the occurrence of given morphological types used in the proposed method. As a part of this, on the basis of these frequencies, simulations were performed, which enabled us to recognize new angle distributions used in orientation studies. These distributions already contain information on the frequency of the appearance of galaxies of particular morphological types in clusters, allowing for more accurate results of the statistical tests carried out during the analysis. The method is an extension of results developed in in our previous investigations. Full article
