Small-Scale HI Channel Map Structure is Cold: Evidence from Na I Absorption at High Galactic Latitudes
J. E. G. Peek, S. E. Clark
The spatial distribution of neutral hydrogen (H I) emission is a powerful probe of interstellar medium physics. The small-scale structure in H I channel maps is often assumed to pr…
Do Androids Dream of Magnetic Fields? Using Neural Networks to Interpret the Turbulent Interstellar Medium
J. E. G. Peek, Blakesley Burkhart
The interstellar medium (ISM) of galaxies is composed of a turbulent magnetized plasma. In order to quantitatively measure relevant turbulent parameters of the ISM, a wide variety…
Catching the Birth of a Dark Molecular Cloud for the First Time
Pei Zuo, Di Li, J. E. G. Peek +5
The majority of hydrogen in the interstellar medium (ISM) is in atomic form. The transition from atoms to molecules and, in particular, the formation of the H molecule, is a ke…
Optically thick HI does not dominate dark gas in the local ISM
Claire E. Murray, J. E. G. Peek, Min-Young Lee +1
The local interstellar medium (ISM) is suffused with "dark" gas, identified by excess infrared and gamma ray emission, yet undetected by standard ISM tracers such as neutral hydrog…
