Detection of Interstellar C_2 and C_3 in the Small Magellanic Cloud
Daniel E. Welty, J. Christopher Howk, Nicolas Lehner +1
We report the detection of absorption from interstellar C_2 and C_3 toward the moderately reddened star Sk 143, located in the near 'wing' region of the SMC, in optical spectra obt…
Ionized Gas in the First 10 Kiloparsecs of the Interstellar Galactic Halo: Metal Ion Fractions
J. Christopher Howk, S. Michelle Consiglio
We present direct measures of the ionization fractions of several sulfur ions in the Galactic warm ionized medium (WIM). We obtained high resolution ultraviolet absorption line spe…
High-velocity clouds as streams of ionized and neutral gas in the halo of the Milky Way
N. Lehner, J. C. Howk, C. Thom +4
High-velocity clouds (HVC), fast-moving ionized and neutral gas clouds found at high galactic latitudes, may play an important role in the evolution of the Milky Way. The extent of…
