The role of diffuse matter in galactic coronas

An upper limit to the gas content in the coronas of giant galaxiesMgas<0.04Mcor has been calculated on the basis of observational data on the emission of clusters of galaxies in different wavelength ranges. An analysis of companion galaxies has revealed a correlation of their morphological types with the distances to central giant galaxies. A gasodynamical interpretation of this regularity is suggested and a possible picture of the evolution of the galactic coronas is presented.
