The polarimetry of the BL Lac objects. popup.stage_title Head Pronik V.I., Registration Date 27-02-2006 Organization Crimean Astrophysical Observatory popup.description2 We have obtained 126 spectra of the active galactic nuclei and more then 1200 estimates of the brightness of the active galactic nuclei. The profiles of the broad hydrogen lines in spectrum of NGC 5548 obtained during 30 years were processed and studied. The evolution of the profile shape of the Hb line is well agree with the model, in which the broad line region consistence with the numerous optical-thick for Lyman continuum quanta gaseous clouds, which are rotated around the massive black hole, approximately in the same plane.
