Summary● Massive galaxies hosting quasars exhibit a massive
and enriched reservoir of cool gas, in absorption (QPQ)– 1011 Msun, ~1/3 solar– Fuel for future SF– Highly improbable that quasars quench galaxies
● Massive galaxies hosting quasars exhibit a massive and enriched reservoir of cool gas, in emission (ELAN)– Illuminating the CGM and nearby IGM (d>300 kpc)– Kinematic characteristic of dark matter halo potential
(FWHM ~ 500 km/s)– Lya Luminosity and absence of HeII imply clumpy, dense
(>102 cm-3) gas not currently captured by hydro simulations
