Study of BTA, Hubble, and Spitzer GRB 021004 deep fields
1 Institute of Astronomy RAS, Russia ;
2 Saint Petersburg State University, Russia
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-meter telescope (BTA), Spitzer and Hubble Space Telescope. BTA BVRI images were used, as well as F475W, F606W, F814W of ACS at the Hubble Space Telescope and Spitzer IRAC ch1 3.6 μm, ch3 5.7 μm. Each BTA BVRI exposure was about one-hour long, reaching objects up to the ~27th stellar magnitude. The GRB 021004 field was investigated. A catalog of 874 discovered objects is being made as well as color diagrams and Hubble diagram for these objects.
