Clumps in a Cocoon: Geometry and Mixing Set the Universal X-ray to H$\alpha$ Surface Brightness Ratio

Zirui Chen, S. Peng Oh, Drummond B. Fielding +3

Recent observations reveal a universal X-ray to H$\alpha$ surface-brightness ratio, ${\mathrm{SB}}_{\mathrm{X}}/{\mathrm{SB}}_{\mathrm{H}\alpha }\sim 3$, in galactic winds, ram-pressure stripped tails, and clust…
