HST/COS Observations of Quasar Outflows in the 500-1050 Å Rest Frame: III. Four Similar Outflows in 2MASS J1051+1247 with Enough Energy to be Major Contributors to AGN Feedback

Abstract

We detect four very energetic outflows in the Hubble Space Telescope/Cosmic Origin Spectrograph spectra of quasar 2MASS J1051+1247 with a combined kinetic luminosity ($\dot{E_k}$) of 10${}^{46}$ erg s${}^{-1}$. Remarkable similarities are seen in these outflows: velocity centroids between 4900 and 5700 km s${}^{-1}$, distances from the central source ($R$) of a few hundred parsecs that are all consistent within the errors, and an $\dot{E_k}$ within a factor of two for all outflows. Hence, a common origin for the outflows is probable. Most of the outflowing mass resides in a very high-ionization phase evident by troughs from Ne VIII, Na IX, Mg X, and Si XII, which connect the physical conditions of these ultraviolet outflows to the X-ray warm absorber outflows seen in nearby Seyfert galaxies. Three of the outflows have two or three independent diagnostics for the electron number density, yielding consistent values for each outflow, which increase the robustness of the $R$ determinations. Troughs from never-before-seen ionic transitions of Ar VI, O IV*, Ne VI*, and Ne V* are identified. With a combined $\dot{E_k}$ that is $7.0_{-2.3}^{+6.5}$ % of the quasar's Eddington luminosity, these outflows are prime candidates to be major agents for various active galactic nuclei feedback effects.
