The Multi-phase HI of the Milky Way and Nearby Galaxies

Marc-Antoine Miville-Deschênes, J. R. Dawson, Narendra Nath Patra +30

Atomic hydrogen (HI) is the dominant baryonic component of the interstellar medium (ISM) in Milky Way-like galaxies and the reservoir from which molecular clouds and stars ultimate…

Revealing the cold skeleton of the Magellanic Clouds and the Magellanic Bridge with ASKAP

James Dempsey, N. M. McClure-Griffiths, Antoine Marchal +14

We present the GASKAP-HI pilot absorption survey of neutral hydrogen (HI) in the Magellanic system. This survey provides 3219 sightlines across the Large (LMC) and Small Magellanic…

Modeling the Milky Way wind: Supernova-driven outflows accelerate HI clouds near the Galactic center

Andrea Afruni, Enrico M. Di Teodoro, Lucia Armillotta +2

Multiwavelength observations, from radio to X-rays, have revealed the presence of multiphase high-velocity gas near the center of the Milky Way likely associated with powerful gala…

A High-resolution Study of the Cold Neutral Medium in and around 30 Doradus

Gyueun Park, Min-Young Lee, John M. Dickey +17

With the aim of evaluating the roles of the cold neutral medium (CNM) in the cloud-scale baryon cycle, we perform a high-resolution study of the CNM in and around the extreme star-…

Study of HI Turbulence in the SMC Using Multi-point Structure Functions

Bumhyun Lee, Min-Young Lee, Jungyeon Cho +19

Turbulence in the interstellar medium (ISM) plays an important role in many physical processes, including forming stars and shaping complex ISM structures. In this work, we investi…

Multi-wavelength probes of the Milky Way's Cold Interstellar Medium: Radio HI and Optical KI Absorption with GASKAP and GALAH

Hiep Nguyen, Sven Buder, Juan D. Soler +19

We present a comparative analysis of interstellar hydrogen (HI) and potassium (KI) absorption from the radio and optical surveys, GASKAP and GALAH, to study the physical and kinema…
