The high-velocity outflow of PG 1211+143 may not be that fast.

Abstract (from CDS):

We analyze the X-ray spectrum of the quasar PG 1211+143 observed with the CCD and grating spectrometers on board XMM-Newton. Using an ion-by-ion fitting model, we find an outflow component of about 3000 km/s, which includes absorption lines of K and L shell ions of the astrophysically abundant elements. We also identify and include in our model broad (FWHM=6000 km/s) emission lines from H-like ions of C, N, O, and Ne, and He-like ions of O, Ne, and Mg. The outflow velocity we find is an alternative interpretation of the data and is in contrast with the ultra high velocity of ∼24,000 km/s reported previously for this object. Nevertheless, we cannot completely rule out the presence of a high-velocity component due to the poor signal-to-noise ratio of the data.
