摘要:
The results of an optical an infrared investigation of a complete subsample of the Leiden-Berkeley Deep Survey are presented. Optical counterparts have been identified for 69 of the 73 sources in the two Hercules fields, and redshifts obtained for 49 of them. Photometric redshifts are computed from the griK data for the remaining 21 sources. This complete sample is compared with the radio luminosity functions (RLFs) of Dunlop and Peacock (1990) [1]. The RLF models successfully trace the evolution of the radio sources with redshift, but there is some disagreement between the luminosity-dependence of the models and the data. The observed RLF for the lower luminosity population(log10P<26)shows evidence for a cut-off at lower redshifts(z∼0.5–1.5)than for the more powerful objects. ©1999 American Institute of Physics.
