SUMMARY OF SEQUENCE NUMBER 700156
Title: X-RAYS FROM RADIO-LOUD BROAD ABSORPTION LINE QSOS
Observer: BROTHERTON
Subject Category: Active Galaxies and Quasars
Seq: 700156 ObsId: 00851
Long-term Plan bin: 2-Apr-2000
ABSTRACT
We propose AXAF ACIS-I observations of several newly discovered radio-loud Broad Absorption Line QSOs (BAL QSOs). Previous ROSAT observations of radio-quiet BAL QSOs, which were the only kind known until recently, show that they are X-ray quiet compared to normal radio-quiet QSOs. This surprising result implies BAL QSOs are either (1) intrinsically X-ray-quiet, or (2) absorbed by high column density material (N_H ~ 10^23 cm^-2). ASCA Observations of PHL 5200 suggest the latter. Because Radio-loud QSOs are more X-ray bright than radio-quiet QSOs, AXAF is able to obtain spectra of our radio-loud BAL QSOs in modest exposure times and verify that they are normal but absorbed radio-loud QSOs. These data will help us to understand the relationship between QSO absorption and radio properties.
