Linking simulations and observations of star-forming regions I. Masses and temperatures of ALMAGAL-like cores
Birka Zimmermann, Álvaro Sánchez-Monge, Stefanie Walch +1
Dense cores and clumps in massive star-forming regions are studied through (sub-)millimetre continuum observations, but inferred masses and temperatures can be biased by limited re…
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…
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, i…
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…
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 Molecular Cloud Lifecycle II: Formation and Destruction of Molecular Clouds Diagnosed via H Fluorescent Emission Emission
Blakesley Burkhart, Shmuel Bialy, Daniel Seifried +11
Molecular hydrogen (H) formation and dissociation are key processes that drive the gas lifecycle in galaxies. Using the SImulating the LifeCycle of Molecular Clouds (SILCC) zoo…
Modelling the chemical evolution of star forming filaments
D. Seifried, S. Walch
We present simulations of star forming filaments incorporating - to our knowledge - the largest chemical network used to date on-the-fly in a 3D-MHD simulation. The network contain…
Modelling the chemistry of star forming filaments - H and CO chemistry
D. Seifried, S. Walch
We present simulations of star forming filaments incorporating on of the largest chemical network used to date on-the-fly in a 3D-MHD simulation. The network contains 37 chemical s…
