Comparison between Optically Selected and X-Ray Selected Active Galactic Nuclei
We compare statistical properties on optically selected and X-ray selected Active Galactic Nuclei by using the available data on the corresponding distributions of the X-ray to optical luminosity ratio. We show that these computations critically depend on the width of these distributions. The use of the observed ones leads to significant inconsistencies between predictions and observations. However, if we assume that these distributions have boon “broadened” by external effects, and consequently we use narrower intrinsic widths, we can eliminate most of the discrepancies.
