... The search for distant objects which can be both galaxies and quasars is one of the most important problems of observational astrphysics, because it allows one to determine cosmological parameters connected with the time of appearence and evolution of stellar systems, large scale structure of the Universe. ... Radio galaxies are important objects to be studied because they are sources of infrared-optical-ultraviolet continuum, emission lines and continual radio emission. ...

... About half an hour after the BAT trigger, the first images were obtained with the SAO RAS Zeiss-1000 telescope in four BVRI filters (see Fig.1). ... The spectrum of the optical transient was obtained with the SAO RAS 6-m BTA telescope 1.54 hours after the burst, using the SCORPIO instrument in the spectroscopic mode (Fig.2). ... The spectrum of the optical transient GRB090726 with identified lines, obtained with the BTA 1.54 hours after the burst. ...
