Mass budget

• X-ray gas?• Ionization/

Metallicity?• Shortfall at

low mass?

from Molly Peeples

Phase Space Structure1012 M• Hot gas

• Satellites• High covering frac• Interface OVI –

only close in?

Gas Dynamics

• Outflows:– Correlates w/SSFR

– Theta grows w/z– vwind/vesc grows w/z

• Inflows:– Seen in ~few%– Required for fuel?– Equilibrium works!

High-z winds: IGM

Low-z winds: Halo fountains

Outside-In Cosmic Enrichment

Offset inflows

Simulations• CGM more

challenging than IGM/gals

• Key: Dynamics of outflows, metal mixing

• It’s all about where you put the metals

• Constraints: IGM Z, GSMF

What Next?

• Work on including more pie charts

• Give a big thanks Rob & Ben!

• Go out and enjoy the weather! (just as Ben predicted)
