Reverberation mapping of the emission line regions of Seyfert galaxies and quasars
Abstract
An indirect method is outlined for mapping the emission line regions of Seyfert galaxies and quasars having variable line intensities and profiles, provided that (1) the galactic nuclei in question comprise a compact, central continuum source surrounded by an extended distribution of line-emitting gas, and (2) that the covering factor of the gas be small and the entire region optically thin to Thomson scattering so that most continuum and line photons may escape directly from the nucleus. The results obtained are demonstrated by means of models in which the line luminosity of an element of gas is directly proportional to the incident observed continuum flux. Additional assumptions justified on physical grounds are rapid reprocessing and the stability of the gas distribution over several light crossing times.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
