An Atlas of Far Ultraviolet Spectroscopic Explorer Sight Lines toward the Magellanic Clouds

Abstract

We present an atlas of 57 Large Magellanic Cloud (LMC) and 37 Small Magellanic Cloud (SMC) observations obtained with the Far Ultraviolet Spectroscopic Explorer (FUSE) satellite. The atlas highlights 12 interstellar absorption-line transitions at a resolution of ~15 km s-1. These transitions cover a broad range of temperatures, ionization states, and abundances. The species included are O VI, which probes hot (T~3×105 K) ionized gas; C III and Fe III, which probe warm (T~104 K) ionized gas; Si II, P II, C II, Fe II, and O I, which probe warm neutral gas; and six different molecular hydrogen transitions, which trace cold (T
