Scientific paper

Radiation and MHD driven accretion disk winds are reaching a level of maturity in explaining the observational signatures of quasars in the broad emission (and absorption) line regions. Further advancement of the models requires additional empirical input to provide observational constraints. One of the most robust indicators of a disk wind (other than broad absorption troughs) is the blueshift of the CIV emission line with respect to the systemic redshift. This proposal seeks to obtain good S/N (~100 counts) Chandra observations of 18 bright SDSS quasars (189.2 ks in total) in order to confirm a previous trend seen in joint spectral fitting of exploratory observations of large CIV blueshift quasars and to test radiation driven wind models for radio quiet quasars.
