Environments of QSOs at intermediate redshifts
Klaus Jaeger, Klaus J. Fricke, Jochen Heidt
Abstract
A preliminary analysis of fields around 20 mainly radio-quiet QSOs (RQQs) at intermediate redshift is summarized. We find overdensities of faint sources around 50% of our observed QSOs suggesting that they are located in groups or even clusters of galaxies.
