... 2003; Sarzi et al. 2006), and the limits on nuclear radio emission are also stringent: <1.5 mJy at 15 GHz (with 150 mas resolution; Nagar et al. 2005) and <0.5 mJy at 5 GHz (with 500 resolution; Wrobel & Heeschen 1991). ... NGC 821 lies 1.5 from the phase calibrator. ... If the 5 GHz detection is real, and the nuclear X-ray emission is smaller by a factor of k2 than the upper limit, then NGC 821 is consistent with the plane, and it may host a radiatively inefficient accretion flow+jet system. ...

In x 3 we discuss normal galaxies in terms of their LX /LB evolution, log (N )-log (S ) relation, and X-ray luminosity function. ... Therefore, to further separate AGNs from normal galaxies, we use several diagnostics: the X-ray luminosity, X-ray to optical flux ratio, X-ray spectral hardness, and optical line ratios. ...

The spatially resolved, high-quality XMM-Newton spectra provide enough statistics to formally require at least three emission components in each of four circumnuclear concentric shells (within 50 or 100 kpc): two soft thermal components indicating a range of temperatures in the hot ISM plus a harder component, consistent with the integrated output of low-mass X-ray binaries ( LMXBs) in NGC 507. ...

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.
