The MUNICs project -- a multicolor survey of distant galaxies


Abstract in English

The MUNICS project is an ongoing imaging survey designed to cover 3 sq. degrees in V,R,I,J,K. We describe here partial results of the project concerning the clustering properties of K < 19.5 galaxies in scales of 3.6 to 63.0 over an area of $sim 800 arcmin^2$. We present K data for a sample of 20 fields, five of which contain $z > 0.5$ radio-loud quasars with steep spectra, eight contain $z > 0.5$ radio-loud quasars with flat spectra and seven are high-galactic latitude fields with no quasars in them. The two-point angular correlation function for the total sample shows significant clustering at $sim 5 sigma$ level of K=19.5 galaxies. The correlation angle of the galaxies is $theta_0 = 1.7 pm 0.4$ for K < 19 mag and $theta_0 = 1.0 pm 0.2$ for K < 19.5 mag. When the correlation functions for the subsamples are considered, the mean $omega(theta)$ amplitude of the fields which contain steep-spectra $z > 0.5$ radio-loud quasars is determined to be $sim 2.0 - 2.5$ that of the high-galactic latitude fields.
