Spectral optical monitoring of 3C390.3 in 1995-2007: I. Light curves and flux variation of the continuum and broad lines
A. I. Shapovalova, L. C. Popovic, A. N. Burenkov +9
Here we present the results of the long-term (1995-2007) spectral monitoring of the broad line radio galaxy \object{3C~390.3}, a well known AGN with the double peaked broad emissio…
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…
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…
