HST/COS Observations of Quasar Outflows in the 500-1050 Angstrom Rest
  Frame: VII. Distances and Energetics for 11 Outflows in Five Quasars
  From Hubble Space Telescope/Cosmic Origins Spectrograph spectra of five
quasars, 16 outflows are detected. For 11 outflows, we are able to constrain
their distances to the central source (R) and their energetics. In instances of
multiple electron number density determinations (used in the calculation of R)
for the same outflow, the values are consistent within errors. For the 11
outflows, eight have measurements for R (between 10 and 1000 pc), one has a
lower limit, another has an upper limit, and the last has a range in R. There
are two outflows that have enough kinetic luminosity to be major contributors
to active galactic nucleus feedback. The outflowing mass is found primarily in
a very high-ionization phase, which is probed using troughs from, e.g., Ne
VIII, Na IX, Mg X, and Si XII. Such ions connect the physical conditions of
these ultraviolet outflows to the X-ray warm absorber outflows seen in nearby
Seyfert galaxies. The ion Cl VII and several new transitions from Ne V have
been detected for the first time.
