dc.descriptionWe study the 36 brightest radio sources in the Subaru/XMM-Newton Deep Field SXDF). Using MIPS 24 micron data from Spitzer we expect to trace accretion activity, even if it is hidden at optical wavelengths, unless the obscuring column is extreme. Our results suggest that in the decade or so below the break in the radio luminosity function that at least half, and potentially nearly all, radio sources are associated with accreting quasar-like objects. This is not true at lower radio luminosities where the quasar-like fraction approaches zero once compact sources are excluded.
