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…
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…
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…
