Analytical approximation of the emission line Fe in QSO's spectra
S. V. Repin, V. N. Lukash, V. N. Strokov
In spectra of many Seyfert galaxies there is a wide emission line of Fe . The line profile with two maxima supposes that the line emerges in innermost regions of an accretion…

Different Types of Fe K_αLines from Radiating Annuli near Black Holes
Alexander F. Zakharov, Serge V. Repin
Recent X-ray observations of microquasars and Seyfert galaxies reveal the broad emission lines in their spectra, which can arise in the innermost parts of accretion disks. A theore…

Magnetic fields in AGNs and microquasars
A. F. Zakharov, N. S. Kardashev, V. N. Lukash +1
Observations of AGNs and microquasars by ASCA, RXTE, Chandra and XMM-Newton indicate the existence of wide X-ray emission lines of heavy ionized elements in their spectra. The emis…
