20 A. shock-heated dust grains, line emission, synchrotron emission. (molecular or ionic shocks or PAH emission) B. complete or partial shells, partial filaments or combination filaments  generally coincide with the radio continuum

21

22 1.HII regions of the galactic plane(~8um), PAH(~8um), star light (~3.6um)  IPAC tell us little information about dust emission 2.Molecular shock =/= OH masers(more strict)

25 Sloan Digital Sky Survey 1E (SMC 52kpc)

26 1.The 24 um distribution decreases less sharply than the X-ray distribution. 2.IR emission peaks around 24um(OIV25.88um, FeII25.98um [RCW103, CasA]), and sharply falls off toward shorter and longer wavelengths.
