In this proposal, we plan to study the relation between the inner part of the wind which is likely to be shielding the X-ray emission and the UV winds characterized by broad absorption lines (BALs). To address this, we propose to probe the shield-wind connection in the highly X-ray variable BALQSO PG 2112+059, which has exhibited periods of X-ray weakness and X-Ray "normality" in the past. ------------------------------------------------------------------------------------ Observations Description ------------------------ The observations will be performed in two different orbits. In each HST observation orbit we requiere at least an 840 s exposure with the G230L grating and a 1000 s exposure with the G140L to get a S/N~30 in the continuum, suffcient for high quality studies of the key O vi, Ly, N v, and C iv absorption lines. Each HST observation orbit must be contemporaneous to two Chandra observations. Therefore, we require that each HST orbit observation is within a month of its respective Chandra observation counterpart. Additionally each set of Chandra-HST observations must be separated by at least eight months. ------------------------------------------------------------------------------------ 13948( 3) - 30-Oct-2014 13:39:35 -
