XMM-NewtonDetection of the Rare Fanaroff-Riley Type II Broad Absorption Line Quasar FIRST J101614.3+520916

We have detected FIRST J101614.3+520916 with the XMM-Newton X-rayObservatory. FIRST J101614.3+520916, one of the most extreme radio-loud, broadabsorption line (BAL) quasars so far discovered, is also a Fanaroff-Riley typeII (FR II) radio source. We find that, compared to its estimated intrinsicX-ray flux, the observed X-rays are likely suppressed, and that the observedhardness ratio indicates significant soft X-ray photons. This is inconsistentwith the simplest model, a normal quasar spectrum absorbed by a large neutralHI column density, which would primarily absorb the softer photons. Morecomplex models, involving partial covering, an ionized absorber, ionized mirrorreflection, or jet contributions need to be invoked to explain this source. Thesuppressed but soft X-ray emission in this radio-loud BAL quasar is consistentwith the behavior displayed by other BAL quasars, both radio-loud andradio-quiet.Comment: 5 pages, 2 figures.
