VLT/UVES Observation of the Outflow in Quasar SDSS J1439-0106

Abstract

We analyze the VLT/UVES spectrum of the quasar SDSS J143907.5-010616.7, retrieved from the UVES Spectral Quasar Absorption Database. We identify two outflow systems in the spectrum: a mini broad absorption line (mini-BAL) system and a narrow absorption line (NAL) system. We measure the ionic column densities of the mini-BAL ($v=-1550$ km s${}^{-1}$) outflow, which has excited state absorption troughs of Fe II. We determine that the electron number density $\log n_e=3.4_{-0.1}^{+0.1}$ based on the ratios between the excited and ground state abundances of Fe II, and find the kinetic luminosity of the outflow to be $\lesssim 0.1\%$ of the quasar's Eddington luminosity, making it insufficient to contribute to AGN feedback.
