Abstract:
We use the RATAN-600 radio telescope for picking up the most distant
objects in the Universe. As a first step, about 100 steep spectrum
FRII radio galaxies (SS FRII RG) from the RATAN-600 RC catalog
(Parijskij et al., 1991, Cat. J/A+AS/87/1; 1992A&AS...96..583P 1992A&AS...96..583P) were
mapped by the VLA and identified with optical objects down to 24-25 R
mag. All the VLA images and all the deep CCD images of the RC SS
fields, collected up to now, are given. An updated list of calibrators
with the known redshifts of the same SS FRII class RGs was compiled to
estimate photometric redshifts, redshifts from angular size - redshift
relations and by the radio "standard candle" method. The mean redshift
of the RC SS FRII RG list happened to be greater than 2. BVRI
photometry was made, and by standard model fittings we estimated
"color" redshifts and the ages of stellar systems of the parent gE
galaxies in 14 cases. Several objects were found in which active star
formation began in the first billion years after the Big Bang. We
believe that more than 10000 of such old active galaxies are available
on the sky and all of them are in the range of present day optical and
radio facilities.
