Scientific paper

We used the long term spectroscopical observations of Mrk 110, HeII 4686, HeI 5876,Halpha and Hbeta lines (Kollatschny 2003, A&A, v.407, p.461, and A&A, 412, 61) in order to investigate the gravitational field influence on spectral line profiles predicted by Popovic (1995, A&A, 293, 309). We found a good agreement between observed line profiles and theoretical predictions. We found the different influence of a strong gravitational field on BLR emission in different periods, i.e. in different periods the gravitation field of central black hole has different contributions to the line profiles and shift. From this we can conclude that the lines are more intensive where emission is originating closer to the central black hole.
