Scientific paper

The Swift BAT (14-195 keV) X-ray survey has currently identified a sample of 250 nearby (z = 0.03) AGNs. Among these, two sources have very unusual multi-wavelength properties which have strong implications for understanding similar sources detected in deep surveys. In the optical, NVSS 193013+341047 and IRAS 05218-1212 show broad lines, while their XRT (0.3-10 keV) spectra suggest these sources are heavily absorbed and possibly Compton-thick. Further, the IR properties of these sources place them among the most heavily extincted with unusual SEDs, comparable only to high redshift EROs. With 15 ks XMM-Newton EPIC observations of both unusual sources, we will constrain the X-ray properties of these sources, trying to determine the origin of this unusual (at high flux) behavior.
