(2013ApJ...763L..42C), we used halo abundance matching applied to 182 galaxies in the MgII Absorber-Galaxy Catalog (MAGIICAT) and showed that the mean MgII{lambda}2796 equivalent width follows a tight inverse-square power law, W_r_(2796){prop.to}(D/R_vir_)^-2^, with projected location relative to the galaxy virial radius and that the MgII absorption covering fraction is effectively invariant with galaxy virial mass, M_h_, over the range 10.7<=logM_h_/M_{sun}_<=13.9. In this work, we explore multivariate relationships between W_r_(2796), virial mass, impact parameter, virial radius, and the theoretical cooling radius that further elucidate self-similarity in the cool/warm (T=10^4^-10^4.5^K) circumgalactic medium (CGM) with virial mass. We show that virial mass determines the extent and strength of the MgII absorbing gas such that the mean W_r_(2796) increases with virial mass at fixed distance while decreasing with galactocentric distance for fixed virial mass. The majority of the absorbing gas resides within D=~0.3R_vir_, independent of both virial mass and minimum absorption threshold; inside this region, and perhaps also in the region 0.3<D/R_vir_<=1, the mean W_r_(2796) is independent of virial mass. Contrary to absorber-galaxy cross-correlation studies, we show there is no anti-correlation between W_r_(2796) and virial mass. We discuss how simulations and theory constrained by observations support self-similarity of the cool/warm CGM via the physics governing star formation, gas-phase metal enrichment, recycling efficiency of galactic scale winds, filament and merger accretion, and overdensity of local environment as a function of virial mass.2013ApJ...779...87Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/779/87CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/776/114 : MAGIICAT.
