- W17608610 abstract "This review discusses the present understanding of the inner region of AGN. Several fundamental questions are adressed, such as the determination of the central mass, the accretion rate and the presence or absence of massive accretion disks. The “standard model”, used until recently to deduce the density, ionization, geometry and other physical properties of AGN, is facing sever difficulties and several unsolved problems, such as the hydrogen line ratio, the FeII spectrum, the energy budget discrepency and the confinement of the broad line clouds may force us to abandon it all together. The new line-continuum reverberation measurements are perhaps the most important developement of recent years and their significance is discussed in relation to the other mentioned problems. Thin or thick accretion disks are likely to be present in the very center of AGNs. The theory of such disks is not advanced enough to provide accurate spectral calculations and the best way to identify them is to look for the signature of their nonisotropic radiation field in well selected samples. Several new developements and ideas, such as disk shaped emission line region, stars and stellar winds as broad line clouds, dust emission and very small-very dense BLR are also discussed." @default.
