First J1556+3517, Xmm-Newton Proposal 02040501

Scientific paper

We propose a 40 ks EPIC observation of the low-ionization broad absorption line (LoBAL) quasar FIRST 1556+3517. BAL quasars are X-ray faint and only since the advent of XMM and Chandra have they been routinely detected. Initial surveys reveal that the high-ionzation BAL (HiBAL) quasars are the X-ray brightest of the class and are apparently normal quasars with moderate to high line-of-sight absorbing column densities. LoBAL quasars are significantly fainter in the X-rays. The red, radio-loud BALQSO FIRST 1556+3517, a short-exposure target of both Chandra and XMM, is the X-ray brightest LoBAL quasar known at high redshifts and luminosities. The spectrum is too soft and faint to result from simple absorption, and is probably relfected as in Seyfert 2 galaxies.
