+ Galactic Winds Veilleux, Cecil, & Bland-Hawthorn, 2005, ARAA, 43, 769 M 82
10
Important Questions How common are galactic winds? What is the impact of galactic winds on Galaxy evolution? Galaxy formation? The intergalactic medium?
11
Dust Outflow: SST IRAC (Engelbracht et al. 2006)
12
Dust Outflow Importance: dM/dt dust ~ 1% dM/dt neutral ? Implications: intergalactic dust? (e.g., Coma ICM; Stickel+98) 850 m 2 nd -year project of Alex McCormick: Search for dusty galactic winds in the Spitzer archive
