X-Ray Absorption Associated with High-Velocity UV Absorbers


We present Chandra observations of two radio-quiet QSOs, PG 2302+029 and PG 1254+047. PG2302+029 has an ultra high-velocity UV absorption system (∼ −56, 000 km s), while PG 1254+047 is a Broad Absorption Line (BAL) QSO with detached troughs. Both objects are X-ray weak, consistent with the known correlation between αox and the strength of the UV absorption… (More)
