摘要: We present measurements of the clustering properties galaxies in field redshift range 0.5 ≤ z 1.5 Ultra Steep Spectrum radio sources selected from Sydney University Molonglo Sky Survey and National Radio Astronomy Observatories Very Large Array Survey. Galaxies these USS fields were identified deep near-infrared observations, complete down to K s = 20, using IRIS2 instrument at Anglo-Australian Telescope. used distribution < 20 taken Cimatti et al. (2002) constrain correlation length r 0 . find a strong signal with around our sample. A comoving 14.0 ± 2.8 h -1 Mpc y 1.98 0.15 are derived flat cosmological model universe. compare findings those obtained N-body simulation populated GALFORM semi-analytic galaxies. that clusters masses M 10 13.4-14.2 2 ⊙ have cluster-galaxy cross-correlation amplitude comparable found between hosts These results suggest distant excellent tracers galaxy overdensities pinpoint progenitors day rich
