On the origin of V-shaped polarisation spectra in molecular clouds
Daniel Seifried, Stefanie Walch, Thorsten Balduin
We extend previous theoretical works to gain a better understanding of the origin of observed polarisation degree spectra of molecular clouds, which show a so-called V-shape, i.e.…
Unravelling the structure of magnetised molecular clouds with SILCC-Zoom: sheets, filaments and fragmentation
S. Ganguly, S. Walch, D. Seifried +2
To what extent magnetic fields affect how molecular clouds (MCs) fragment and create dense structures is an open question. We present a numerical study of cloud fragmentation using…
How do supernova remnants cool? -- I. Morphology, optical emission lines, and shocks
Ekaterina I. Makarenko, Stefanie Walch, Seamus D. Clarke +4
Supernovae (SNe) inject erg in the interstellar medium, thereby shocking and heating the gas. A substantial fraction of this energy is later lost via radiative cooli…
Tree-based solvers for adaptive mesh refinement code FLASH -- IV: An X-ray radiation scheme to couple discrete and diffuse X-ray emission sources to the thermochemistry of the interstellar medium
Brandt A. L. Gaches, Stefanie Walch, Richard Wünsch +1
X-ray radiation, in particular radiation between 0.1 keV and 10 keV, is evident from both point-like sources, such as compact objects and T-Tauri young stellar objects, and extende…
