An SDSS-V 3D Tomographic Na I Map of the ISM: An Initial Study Towards the Smith Cloud
Timothy McQuaid, Joseph N. Burchett, Kate H. R. Rubin +7
High velocity clouds supply the Milky Way with gas that sustains star formation over cosmic timescales. Precise distance measurements are therefore essential to quantify their mass…
A survey of molecular clouds in the Galactic center's outflow
Enrico M. Di Teodoro, Mark Heyer, Mark R. Krumholz +8
The nucleus of the Milky Way is known to drive a large-scale, multiphase galactic outflow, with gas phases ranging from the hot highly-ionized to the cold molecular component. In t…
A New High-latitude H I Cloud Complex Entrained in the Northern Fermi Bubble
Rongmon Bordoloi, Andrew J. Fox, Felix J. Lockman
We report the discovery of eleven high-velocity HI clouds at Galactic latitudes of 25-30 degrees, likely embedded in the Milky Way's nuclear wind. The clouds are detected with deep…
Ultraviolet Properties of Multi-phase Gas Toward the Inner Galaxy
Frances H. Cashman, Andrew J. Fox, Debopam Som +6
We present a systematic study of the multi-phase interstellar gas in the Inner Galaxy using HST/STIS absorption spectroscopy of 16 massive stars located at spectroscopic distances…
Dust in the Smith Cloud? A UV Investigation into the Smith Cloud's Gas-Phase Abundance Patterns
Johanna Vazquez, Kathleen Barger, Frances Cashman +11
The Smith Cloud is a high-velocity cloud (HVC) on its final approach to the Milky Way that shows evidence of interaction with the Galaxy's disk. We investigate the metallicity and…
