Driven by the imminent need to rapidly process and classify millions of AGN spectra drawn from next generation astronomical facilities, we present a spectral fitting routine for Type 2 optimised high volume processing, using Quasar Spectral Fitting library (QSFit). We analyse an optically selected sample 813 luminous at $z < 0.83$ Sloan Digital Sky Survey (SDSS) qualify its performance. report ...

I estimate Modified-Dynamics (MOND), median M/L values for recently published catalogues of galaxy groups. While the median, Newtonian M/L values quoted for these catalogues are (110 − 200)h75(M/L) , the corresponding values for MOND are less than 10 (M/L) (where the mass includes contributions from galactic, and intra-group gas). Subject headings: Galaxies: kinematics and dynamics; Cosmology: ...
