External (CGM/IGM): What are the CGM kinematics? What is the CGM metallicity? What governs CGM astrophysics? What is the morphology/extent of the CGM?

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
