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…
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…
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…
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…
The origin and evolution of the [CII] deficit in HII regions and star-forming molecular clouds
Stefano Ebagezio, Daniel Seifried, Stefanie Walch +1
We analyse synthetic maps of the [CII] 158 m line and FIR continuum of simulated molecular clouds (MCs) within the SILCC-Zoom project to study the origin of the [CII] deficit,…
