A Galactic Eclipse: The Small Magellanic Cloud is Forming Stars in Two, Superimposed Systems

Claire E. Murray, Sten Hasselquist, Joshua E. G. Peek +22

The structure and dynamics of the star-forming disk of the Small Magellanic Cloud (SMC) have long confounded us. The SMC is widely used as a prototype for galactic physics at low m…

The role of magnetic fields in disc galaxies: spiral arm instability

Raghav Arora, Christoph Federrath, Robi Banerjee +1

Context. Regularly-spaced, star-forming regions along the spiral arms of nearby galaxies provide insight into the early stages and initial conditions of star formation. The regular…

Fundamental MHD scales -- II: the kinematic phase of the supersonic small-scale dynamo

Neco Kriel, James R. Beattie, Christoph Federrath +2

Many astrophysical small-scale dynamos (SSDs) amplify weak magnetic fields via highly compressible, supersonic turbulence, but established SSD theories have overlooked these compre…

A new method for spatially resolving the turbulence driving mixture in the ISM with application to the Small Magellanic Cloud

Isabella A. Gerrard, Christoph Federrath, Nickolas M. Pingel +12

Turbulence plays a crucial role in shaping the structure of the interstellar medium. The ratio of the three-dimensional density contrast () to the turbulent sonic Mach n…

Multiphase Neutral Interstellar Medium: Analyzing Simulation with H I 21cm Observational Data Analysis Techniques

Soumyadeep Bhattacharjee, Nirupam Roy, Prateek Sharma +2

Several different methods are regularly used to infer the properties of the neutral interstellar medium (ISM) using atomic hydrogen (H I) 21cm absorption and emission spectra. In t…

The Rapid ASKAP Continuum Survey III: Spectra and Polarisation In Cutouts of Extragalactic Sources (SPICE-RACS) First Data Release

Alec J. M. Thomson, David McConnell, Emil Lenc +23

The Australian SKA Pathfinder (ASKAP) radio telescope has carried out a survey of the entire Southern Sky at 887.5MHz. The wide area, high angular resolution, and broad bandwidth p…

Measuring the hot ICM velocity structure function using XMM-Newton observations

Efrain Gatuzz, R. Mohapatra, C. Federrath +4

It has been shown that the gas velocities within the intracluster medium (ICM) can be measured by applying novel XMM-Newton EPIC-pn energy scale calibration, which uses instrumenta…

Spatiotemporal dynamics of transonic shock-wave/turbulent-boundary-layer interactions in an overexpanded planar nozzle

Justin Kin Jun Hew, Emanuele Martelli, Mahdi Davoodianidalik +3

We perform a combined numerical and experimental study to investigate the transonic shock-wave/turbulent-boundary-layer interactions (STBLI) in a shock-induced separated subscale p…

Kinematics of Galactic Centre clouds shaped by shear-seeded solenoidal turbulence

Maya A. Petkova, J. M. Diederik Kruijssen, Jonathan D. Henshaw +17

The Central Molecular Zone (CMZ; the central ~ 500 pc of the Galaxy) is a kinematically unusual environment relative to the Galactic disc, with high velocity dispersions and a stee…

Can we observe the ion-neutral drift velocity in prestellar cores?

Aris Tritsis, Shantanu Basu, Christoph Federrath

Given the low ionization fraction of molecular clouds, ambipolar diffusion is thought to be an integral process in star formation. However, chemical and radiative-transfer effects,…
