Efficient analysis routines for single and double peaked Type 2 AGN spectra

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 median narrow line H$\alpha$/H$\beta$ Balmer decrement 4.5$\pm$0.8, alluding presence dust in region (NLR). publish specialised QSFit signal noise ratio general double peaked applied on sub-sample 45 our parent sample. red blue peak velocity separation 390$\pm$60kms$^{-1}$. No trend is found or peaks exhibit systematically different luminosity ionization properties. Emission diagnostics show that all sources are illuminated AGN-powered ionizing continuum. Finally, examine morphology host galaxies find reside merging systems comparable frequency single AGN. This suggests phenomenon likely have bi-conical outflow origin majority cases. publicly release code used analysis produced catalogues this work.
