Magnetic Field Measurement in Black Hole X-Ray Binary Cygnus X-1
E. A. Karitskaya, N. G. Bochkarev, S. Hubrig +5
X-ray binary Cygnus X-1 is microquasar containing historically first candidate to black hole. Paradigm of magnetic disc accretion dominates in theoretical models describing process…
Long-term variability of the optical spectra of NGC 4151: I. Light curves and flux correlations
A. I. Shapovalova, L. C. Popovic, S. Collin +13
Results of a long-term spectral monitoring of the active galactic nucleus of NGC 4151 are presented (11 years, from 1996 to 2006). High quality spectra (S/N>50 in the continuum nea…
Probing the physical properties of the NGC 5548 Broad Line Region using Balmer lines
L. C. Popovic, A. I. Shapovalova, V. H. Chavushyan +4
We investigate the physical characteristics of the Broad Line Region (BLR) of NGC 5548 using the Boltzmann plot (BP) method, that we applied on the Balmer lines observed from 1996…
Profile variability of the H-alpha and H-beta broad emission lines in NGC5548
A. I. Shapovalova, V. T. Doroshenko, N. G. Bochkarev +10
Between 1996 and 2002, we have carried out a spectral monitoring program for the Seyfert galaxy NGC 5548. High quality spectra (S/N>50), covering the spectral range (4000-7500)AA w…
