Statistical excess of foreground galaxies around high-z radiogalaxies.

BENITEZ N., MARTINEZ-GONZALEZ E. and MARTIN-MIRONES J.M.

Abstract (from CDS):

K-band imaging of a sample of 21 radiogalaxies with z∼1.5 reveals the existence of a statistical association of foreground galaxies with the positions of the radiosources. The excess is detected within a 1' radius at a high significance level (>99.8%). K-band light is a good tracer of stellar mass, so this result indicates the existence of an association between foreground mass perturbations and background radiosources, as expected from the magnification bias effect, and confirms previous results obtained for other high-z radio-loud AGN.
