Clark (PhD T., 2015) Kepler’s supernova; Thot (left) and Tcold (right) Tycho’s supernova; Thot (left) and Tcold (right) (Forgive the jet colour scale; I was young and didn’t know better!) Negligible dust manufactured by Type-Ia supernovæ Which means all the iron depleted into dust got there some other way
Clark (PhD T., 2015) Synchrotron @ 160 μm Hot dust @ 160 μm Cold dust @ 160 μm We found 0.11 M☉ of supernova dust in the Crab Nebula Subsequent studies report values across 0.04–0.22 M☉ range

Magellanic Clouds? Roman-Duval+ (2017); Clark+ (in prep.) Herschel! …Except faint structure at the edges got removed as ‘background’, as the map was too small; large- scale features get filtered out. Okay, Planck then! …And Planck is great! But its shortest band is 350μm, so you can’t constrain dust temperature. And beam is 10x worse than Herschel. How about Spitzer? …Only covers the shorter wavelengths, and iffy resolution. Plus, severe non-linearity issues at high surface brightness for 160μm. But there’s always IRAS, right? …Unless you want to observe something that is extended and has very high surface brightness (kike the Magellanic Clouds), where IRAS has severe gain problems. Urm, I suppose I could try using Akari? … Good point. How about JCMT? Or ISO? …Never observed more than tiny parts of the Magellanic Clouds. I suppose that leaves…
