O~{\small VI} absorption in the Milky Way along the Large Magellanic Cloud lines of sight

TL;DR

This study uses FUSE observations to measure O VI absorption in the Milky Way along lines of sight to the LMC, revealing patchy distribution and higher or comparable column densities to the LMC.

Contribution

First measurement of O VI column densities in the MW towards LMC lines of sight, confirming patchiness and higher or comparable values to the LMC.

Findings

Mean O VI column density in MW: log N(O VI)=14.257

O VI absorption is patchy across the MW

Column densities are higher or comparable to those in the LMC

Abstract

We have used \textit{Far Ultraviolet Spectroscopic Explorer (FUSE)} observations of the Large Magellanic Cloud (LMC) to determine the O {\small VI} column densities in the Milky Way (MW) towards 6 LMC lines of sight. The mean column density of O {\small VI} in the MW is found to be log N(O {\small VI})=14.257$_{-0.084}^{+0.096}$. The results confirm the patchiness of O {\small VI} absorption in the MW and the column densities are higher or comparable to the LMC.
