Scientific paper

The discovery and spectroscopic study of two QSOs with very broad absorption troughs are reported. A low-resolution spectrum of the brighter object shows several apparently broad-lined high-excitation absorption systems ranging in velocity, relative to the emission system, up to 22,000 km/s (0.07 c) and with widths up to about 11,000 km/s. When observed at higher (2 A) resolution, some of the absorption is resolved into narrower components.
