Dust charge distribution in the interstellar medium
Juan C. Ibáñez-Mejía, Stefanie Walch, Alexei V. Ivlev +3
We investigate the equilibrium charge distribution of dust grains in the interstellar medium (ISM). Our treatment accounts for collisional charging by electrons and ions, photoelec…
On the resolution requirements for modelling molecular gas formation in solar neighbourhood conditions
P. R. Joshi, S. Walch, D. Seifried +3
The formation of molecular hydrogen (H) and carbon monoxide (CO) is sensitive to the volume and column density distribution of the turbulent interstellar medium. In this paper,…
SILCC-ZOOM: The early impact of ionizing radiation on forming molecular clouds
Sebastian Haid, Stefanie Walch, Daniel Seifried +3
As part of the SILCC-ZOOM project we present our first sub-parsec resolution radiation-hydrodynamic simulations of two molecular clouds self-consistently forming from a turbulent,…
Synthetic [CII] emission maps of a simulated molecular cloud in formation
A. Franeck, S. Walch, D. Seifried +10
The C ion is an important coolant of interstellar gas, and so the [CII] fine structure line is frequently observed in the interstellar medium. However, the physical and chemi…
The SILCC project - V. The impact of magnetic fields on the chemistry and the formation of molecular clouds
Philipp Girichidis, Daniel Seifried, Thorsten Naab +5
Magnetic fields are ubiquitously observed in the interstellar medium (ISM) of present-day star-forming galaxies with dynamically relevant energy densities. Using three-dimensional…
Synthetic CO observations of fibrous filaments: the problems of mapping from PPV to PPP
S. D. Clarke, A. P. Whitworth, R. L. Spowage +5
Molecular-line observations of filaments in star-forming regions have revealed the existence of elongated coherent features within the filaments; these features are termed fibres.…
