资源简介:

Recent spectroscopic observations in the UV band have revealed high velocityoutflows in Narrow Absorption Line (NAL) quasars. We propose to initiate anexploratory survey to identify high velocity outflows of Xray absorbingmaterial in NAL quasars. We will search for possible correlations between theamount of Xray absorption and UV properties of the wind to better understandthe acceleration mechanism of quasar winds. We will place the absorbers of NALquasars in the context of other outflow phenomena and test models for theirnature. The detected Xray brightest objects from the proposed survey will befollowed up with deeper observations to constrain better the kinematic andionization properties of the absorbers and ultimately constrain the mass outflow rates of NAL quasars. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
