|Abstract:||The relative orientation of the axes of extragalactic extended radio sources was first investigated by Willson, who noted that in the 3CR sample there was a tendency for the axes to lie parallel to each other for sources separated by ⪉10° on the sky. Using two larger samples, Sanders has recently concluded that this tendency to align is present at a high confidence level (>3σ) only for distant (z > 0.4) sources. The authors have attempted to verify the effect using two more independent and larger source samples and find no significant tendency for axis alignment. They also investigated a sample formed by adding well-observed radio quasars to 3CR sources and found that, even in this sample, the effect shows up only at a marginally significant level (<2σ).|
