Exploratory XMM-Newton observations of AGNs with intermediate mass black hole

We propose for exploratory observations of 13 low luminosity AGNs with candidateintermediate mass black holes (IMBHs). These objects were discovered in theSDSS. The optical line widthluminosity relation implies black hole masses ofthese AGNs in the range of 1e41e6 Msun. None of the 13 objects has beendetected in the RASS, and their Xray nature has remained unexplored. These AGNsare expected to show most rapid Xray variability and hottest accretion diskemission among all radioquiet AGNs. They are the best candidates to study theeffect of a relatively low mass black hole. Our proposed observations willcharacterize their Xray emission for the first time, extend their spectralenergy distributions and investigate the nature of IMBHs in galactic nuclei. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
