Impact of Cosmic Ray Acceleration on the Early Evolution of Bow Shocks around Massive Runaway Stars
Keito Watanabe, Stefanie Walch, Tim-Eric Rathjen +3
Bow shocks generated from the interaction of winds from massive runaway stars with the interstellar medium have been shown to be prominent particle accelerators through recent -…
SILCC -- IX. The multi-phase interstellar medium at low metallicity
Vittoria Brugaletta, Stefanie Walch, Thorsten Naab +8
The gas-phase metallicity affects heating and cooling processes in the star-forming galactic interstellar medium (ISM) as well as ionising luminosities, wind strengths, and lifetim…
The impact of cosmic ray heating on the cooling of the low-metallicity interstellar medium
Vittoria Brugaletta, Stefanie Walch, Thorsten Naab +6
Low-metallicity environments are subject to inefficient cooling. They also have low dust-to-gas ratios and therefore less efficient photoelectric (PE) heating than in solar-neighbo…
SILCC -- VIII: The impact of far-ultraviolet radiation on star formation and the interstellar medium
Tim-Eric Rathjen, Stefanie Walch, Thorsten Naab +4
We present magnetohydrodynamic simulations of star formation in the multiphase interstellar medium to quantify the impact of non-ionising far-ultraviolet (FUV) radiation within the…
GMF G214.5-1.8 as traced by CO: I -- cloud-scale CO freeze-out as a result of a low cosmic-ray ionisation rate
S. D. Clarke, V. A. Makeev, Á. Sánchez-Monge +6
We present an analysis of the outer Galaxy giant molecular filament (GMF) G214.5-1.8 (G214.5) using IRAM 30m data of CO, CO and CO. We find that the CO…
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…
CO and [CII] line emission of molecular clouds -- the impact of stellar feedback and non-equilibrium chemistry
S. Ebagezio, D. Seifried, S. Walch +3
We analyse synthetic CO, CO, and [CII] emission maps of simulated molecular clouds of the SILCC-Zoom project, which include an on-the-fly evolution of H, CO, and…
Synthetic CO emission and the factor of young molecular clouds: a convergence study
Elisabeth M. A. Borchert, Stefanie Walch, Daniel Seifried +3
The properties of synthetic CO emission from 3D simulations of forming molecular clouds are studied within the SILCC-Zoom project. Since the time scales of cloud evolution and mole…
