... We present preliminary results from two programs to image the host galaxies of radio-quiet quasars in 1.6 micron light using NICMOS camera 2 on HST. The high redshift program consists of QSOs covering the redshift range 0.8 < z < 4.4 and a range of QSO luminosities. Of the six objects for which data have been obtained the results range from no host galaxy detected, to an obvious galaxy with an interacting companion, to a possible high redshift galaxy cluster. ...

... 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). ...
