So, You Want to Study Dust in the 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…
