Abstract The structure and dynamics of the star-forming disk Small Magellanic Cloud (SMC) have long confounded us. SMC is widely used as a prototype for galactic physics at low metallicity, yet we fundamentally lack an understanding its interstellar medium (ISM). In this work, present new model by comparing kinematics young, massive stars with ISM traced high-resolution observations neutral atomic hydrogen (H i ) from Galactic Australian Square Kilometre Array Pathfinder survey....
Turbulence plays a crucial role in shaping the structure of interstellar medium. The ratio three-dimensional density contrast ($\sigma_{\rho/\rho_0}$) to turbulent sonic Mach number ($\mathcal{M}$) an isothermal, compressible gas describes solenoidal compressive modes acceleration field gas, and is parameterised by turbulence driving parameter: $b=\sigma_{\rho/\rho_0}/\mathcal{M}$. parameter ranges from $b=1/3$ (purely solenoidal) $b=1$ compressive), with $b=0.38$ characterising natural...
Magnetic fields are known to play a crucial role in the star formation process, particularly of jets and outflows from protostellar discs. The magnetic field structure forming regions is not always uniform ordered, often containing turbulence. We present grid-based, magneto-hydrodynamical simulations collapse 1$\,\mathrm{M}_{\odot}$ cloud core, investigate influence complex structures on outflow formation, morphology efficiency. compare three cases: field, partially turbulent fully with same...
The interstellar medium (ISM) is ubiquitously turbulent across many physically distinct environments within the Galaxy. Turbulence key in controlling structure and dynamics of ISM, regulating star formation, transporting metals We present first observational measurements turbulence neutral hydrogen entrained hot nuclear wind Milky Way. Using recent MeerKAT observations two extra-planar HI clouds above (gal. lat.$\,\sim7.0^{\circ}$) below lat.$\,\sim-3.9^{\circ}$) Galactic disc, we analyse...
