Interesting Astrophysics: 03-13 Aug, 2009

In addition to the usual crop of galaxy-related papers I tend to find most interesting there have been a rash of both interesting AGN and massive star stellar wind papers. Papers of particular note are Harris & Zaritsky (star formation history of the LMC), Behar (Seyfert galaxy outflows) and three papers by Parkin et. al., Pittard, and Owocki (all related to stellar wind theory).
