AN INVESTIGATION INTO THE RELATIONSHIP BETWEEN THE GLOBAL COVERING FRACTION AND LUMINOSITY OF AN AGN**
We conduct a study of quasars observed by the Sloan Digital Sky Survey (to explore the relationship between the global covering fraction and the luminosity of an AGN The SDSS archives contain found 18 000 quasars with spectra between a redshift of 2 00 and 2 30 which provides spectral coverage of N V, Si IV, C IV and Mg II We find that 3000 of the objects showed absorption troughs with FWHM velocities of 500 km s 1 due to outflows intrinsic to the quasars In each case, the absorption trough is evident and agrees in velocity space between all detectable ions We compare detection fractions for each ion as a function of the l L l of the AGN and find a clear cutoff l L l of approximately 10 46 ergs s 1 where objects less than this cutoff show a significantly lower detection rate of outflows.
