Abstract

I study the effect of the galaxies of the Milky Way subgroup on the chemical enrichment of the diffuse gas within the Local Group. The preferred model predicts that the present-day intergalactic medium mass is 1/22 of the initial baryonic mass and its metallicity is 1/20 Z_\odot. Nearly 80 % of intergalactic metals were produced in the Galactic bulge.
