We derive galaxy source counts at 70 and 160 ЮМm using the Multiband Imaging Photometer for Spitzer (MIPS) to map the Chandra Deep Field-South (CDF-S) and other fields. At 70 ЮМm, our observations extend upward about 2 orders of magnitude in flux density from a threshold of 15 mJy, and at 160 ЮМm they extend about an order of magnitude upward from 50 mJy. ... The new Spitzer data already resolve about 23% of the cosmic far-infrared background at 70 ЮМm and about 7% at 160 ЮМm. ... citations = 94 . ...

... To shed light on the nature of this source, we have analyzed archival data, including the Einstein data, 23 ROSAT observations, and BeppoSAX and ASCA pointings. ... Spectral Analysis We have performed model-пtting analysis of PSPC, BeppoSAX, and ASCA spectral data of X-9. ... The spectral behavior of X-9 let us conclude that this source is not a far-away background QSO (as suggested by Ezoe et al. (2000), who analyzed a set of ASCA/GIS data pointed on M81), but rather an ultraluminous binary in Ho...
