The Far Ultraviolet Spectroscopic Explorer Survey of OVI Emission in the Milky Way
arXiv:astro-ph/0605168 · doi:10.1086/505414
Abstract
We present a survey of OVI 1032 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 July 2003. Our survey contains 112 sight lines, 23 of which show measurable OVI 1032 emission. The OVI 1032 emission feature was detected at all latitudes and exhibits intensities of 1900-8600 photons/s/cm^2/sr. Combined with values from the literature, these emission measurements are consistent with the picture derived from recent OVI absorption surveys: high-latitude sight lines probe OVI-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.
