2. Seyfert galaxies
... By means of deep optical images obtained at the Special Astrophysical Observatory 6-m telescope it was discovered that some Seyfert galaxies that were earlier considered to be non-interacting objects displayed signatures of elongated tidal envelopes belonging to satellite debris. ... Our results suggest that statistic studies based on popular imaging surveys (for example SDSS) can lead to an underestimation of the fraction of minor mergers among galaxies with active nuclei (AGN). ...

6. Conclusions
... The SN 1998bv discovered on April 6, 1998 in the blue compact galaxy HS 1035+4758 is the second supernova observed in a low-mass galaxy with intense SF burst. ... According to its characteristic spectrum, SN 1998bv is a type II supernova with estimated peak absolute brightness M 16.3. The very slow fading of its brightness suggests that the SN was discovered at the Plateau phase, 20-30 days after the peak of the light curve. The most probable classification of SN 1998bv is regular SN II-P. 3. ...
