Query: The clustering of sub-mJy radio sources in The Bootes Deep Field   We measure the angular clustering of ~2000 radio sources in The Bootes Deep
Field, covering 5.3 deg^2 down to S(1.4 GHz)=0.2 mJy. With reference to work by
Blake & Wall, we show that the size distribution of multi-component radio
galaxies dominates the overall clustering signal, and that its amplitude
extrapolates smoothly from their measurements above 5 mJy. The upper limits on
any true galaxy-galaxy clustering are consistent with the clustering of the
sub-mJy radio-loud AGN being effectively diluted by the more weakly-clustered
IRAS-type starburst galaxies. Source count models imply that the survey
contains around 400 of the latter galaxies above 0.2 mJy out to z ~ 1 to 2.
Measurement of their clustering must await their identification via the optical
and infrared data due on this field.
