Obscured active galactic nuclei: the hidden side of the X–ray Universe

Philosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2002
Most active galactic nuclei (AGN) are 'obscured', i.e. the nucleus is hiding behind a screen of absorbing material. The advantage of having the nucleus obscured is to make easier the observations of those emission components which originate in circumnuclear matter outside the absorbing regions, because in this case they are not outshone by the nuclear ...

X-rays from active galactic nuclei ? Hard component

Space Science Reviews, 1981
It is now well known that X-ray emission in active galactic nuclei (AGN) is a fairly common phenomenon (see M.J. Rees’s review in this volume). By examining the recent observational information from Ariel V, HEAO-1, and the Einstein Observatory, we have reached the conclusion (Tsuruta 1981) that the following interpretation may be used as a relevant ...
