This is worth a look. 24 micron photometry alone, seemingly so powerful and robust in the local universe, may lead you astray for certain higher redshift classes of sources.

I have no idea of what to make of this last one.

One Dimensional Dynamical Models of the Carina Nebula Bubble
E. Harper-Clark, N. Murray, arXiv:0812.2906 [ps, pdf, other]
Comments: Accepted to APJ. 47 pages, 13 figures

Hum. Must say my gut feeling is that the conditions in places like the Carina nebula are exactly the right sort to violate the basic assumptions of the models they use, so I'm not too surprised at their results. Still, its always worth actually doing the experiment rather than just supposing the outcome.
