A Highly Doppler Blueshifted Fe-K Emission Line in the High-Redshift QSO PKS 2149-306

{{output}}
We report the results from an ASCA observation of the high-luminosity, radio-loud quasar PKS 2149-306 (redshift 2.345), covering the approximately 1.7-30 keV band in the quasar frame. We find the source to have a luminosity approximately 6x1047 ergs s-1 in the... ...
