A Substantial Mass of Cool, Metal-enriched Gas Surrounding the Progenitors of Modern-day Ellipticals

The hosts of luminous z ~ 2 quasars evolve into today's massive elliptical galaxies. Current theories predict that the circumgalactic medium (CGM) of these massive, dark matter halos (M [subscript DM] ~ 10[superscript 12.5] M [subscript ☉]) should be dominated by a T ~ 10[superscript 7] K viria...
