Feedback and Star Formation Efficiency in High-Mass Star-Forming Regions

Birka Zimmermann, Stefanie Walch, Seamus D. Clarke +2

To advance our understanding of massive star formation, it is essential to perform a comprehensive suite of simulations that explore the relevant parameter space and include enough…

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

The Diamond Ring in Cygnus X: Advanced stage of an expanding bubble of ionised carbon

Simon M. Dannhauer, Sebastian Vider, Nicola Schneider +18

The "Diamond Ring" in Cygnus X, southwest of the DR21 ridge, is a nearly circular structure of 6 pc in diameter, prominent in FIR emission and enclosed by clumpy molecular cl…

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…

Thermal emission from bow shocks. III. Variable diffuse X-ray emission from stellar-wind bow shocks driven by dynamical instabilities

Jonathan Mackey, Arun Mathew, Ahmad A. Ali +5

X-ray emission from wind-driven bow shocks is both difficult to measure and predict, but may give important insights into the energy budget of the hot phase of the ISM by quantifyi…

The Molecular Cloud Lifecycle I: Constraining H2 formation and dissociation rates with observations

Shmuel Bialy, Blakesley Burkhart, Daniel Seifried +9

Molecular clouds (MCs) are the birthplaces of new stars in galaxies. A key component of MCs are photodissociation regions (PDRs), where far-ultraviolet radiation plays a crucial ro…
