The multi-component absorber QSO 0318-0600

This high-quality data set allows us to extract accurate ionic column densities and determine an electron number density of n_e_=10^3.3+/-0.2^cm^-3^ for the main outflow absorption component. The heavily reddened spectrum of SDSS J0318-0600 requires purely silicate dust with a reddening curve characteristic of predominately large grains, from which we estimate the bolometric luminosity.

We carry out photoionization modeling to determine the total column density, ionization parameter, and distance of the gas and find that the photoionization models suggest abundances greater than solar. Due to the uncertainty in the location of the dust extinction, we arrive at two viable distances for the main ouflow component from the central source, 6 and 17kpc, where we consider the 6kpc location as somewhat more physically plausible.
