Abstract

The photometric redshifts were derived, based on photometry data in visual and infrared.Deep fields were observed during gamma-ray bursts investigation with the SAO RAS 6-metertelescope (BTA), Spitzer and Hubble Space Telescope. BTA BVRI images were used, as well asF475W, F606W, F814W of ACS at the Hubble Space Telescope and Spitzer IRAC ch1 3.6μm, ch3 5.7 μm. Each BTA BVRI exposure was aboutone-hour long, reaching objects up to the ~27th stellar magnitude. The GRB 021004 fieldwas investigated. A catalog of 874 discovered objects is being made as well as colordiagrams and Hubble diagram for these objects.
