Observations of Small-Scale Interstellar Structure in Dense Atomic Gas

The Astrophysical Journal, 1999
We present high-resolution (R ~ 170,000) Kitt Peak National Observatory coude feed telescope observations of the interstellar K I λ7698 line toward five multiple star systems with saturated Na I components. We compare the K I absorption-line profiles in each of the two (or three) lines of sight in these systems and find significant differences between ...

Evidence for the Heating of Atomic Interstellar Gas by Polycyclic Aromatic Hydrocarbons

The Astrophysical Journal, 2001
We report a strong correlation between the [C II] 158 ?m cooling line and the mid-infrared flux in the 5-10 ?m range in a wide variety of star-forming galaxies. The mid-infrared flux is dominated by the aromatic features in emission (AFEs), which are thought to arise from large polycyclic aromatic hydrocarbons (PAHs) and are generally associated with ...
