Abstract
We present a survey of O VI λ1032 emission in the Milky Way using data from the Far Ultraviolet Spectroscopic Explorer (FUSE) satellite. The observations span the period from launch in 1999 to 2003 July. Our survey contains 112 sight lines, 23 of which show measurable O VI λ1032 emission. The O VI λ1032 emission feature was detected at all latitudes and exhibits intensities of 1900-8600 photons s-1 cm-2 sr-1. Combined with values from the literature, these emission measurements are consistent with the picture derived from recent O VI absorption surveys: high-latitude sight lines probe O VI-emitting gas in a clumpy, thick disk or halo, while low-latitude sight lines sample mixing layers and interfaces in the thin disk of the Galaxy.
