Here, we discuss the mechanical feedback that massive stellar clusters provide to the interstellar medium of their host galaxy. We apply an analytic theory developed in a previous study for M82-A1 to a sample of 10 clusters located in the central zone of the starburst galaxy M82, all surrounded by compact and dense H II regions. We claim that the

The new transient LMXB in NGC 6440 (CXOGlb J174852.7-202124; Atel #2139) is declining rapidly. RXTE observed NGC 6440 on July 30 (18:47 to 19:26 TT). The PCA top-layer spectrum is well fit with an absorbed power-law of photon index 2.2+-0.1, with N_H set to 6e21 cm^-2 (as found by Chandra). The inferred 0.5-10 keV luminosity is 4e35 ergs/s, a
