Interesting Astrophysics: Mar 09 to Mar 13

A relatively quiet week in terms of interesting papers and preprints. Of particular note this week are Alonso-Herrero et al's Spitzer observations of NGC 3690, Iwasawa et al's study of Fe XXV emission in LIRGs, and Añorve-Zeferino et al's cluster wind + superbubble paper.
