CO line ratios in molecular clouds: the impact of environment
Camilo H. Peñaloza, Paul C. Clark, Simon C. O. Glover +1
Line emission is strongly dependent on the local environmental conditions in which the emitting tracers reside. In this work, we focus on modelling the CO emission from simulated g…
Spatially associated clump populations in Rosette from CO and dust maps
Todor V. Veltchev, Volker Ossenkopf-Okada, Orlin Stanchev +3
Spatial association of clumps from different tracers turns out to be a valuable tool to determine the physical properties of molecular clouds. It provides a reliable estimate for t…
On the Rotation of Supermassive Stars
Lionel Haemmerlé, Tyrone E. Woods, Ralf S. Klessen +2
Supermassive stars born from pristine gas in atomically-cooled haloes are thought to be the progenitors of supermassive black holes at high redshifts. However, the way they accrete…
SPRAI: Coupling of radiative feedback and primordial chemistry in moving mesh hydrodynamics
Ondrej Jaura, Simon C. O. Glover, Ralf S. Klessen +1
In this paper we introduce a new radiative transfer code SPRAI (Simplex Photon Radiation in the Arepo Implementation) based on the SimpleX radiation transfer method. This method, o…
Gravity or turbulence? IV. Collapsing cores in out-of-virial disguise
Javier Ballesteros-Paredes, Enrique Vázquez-Semadeni, Aina Palau +1
We study the dynamical state of cores by using a simple analytical model, a sample of observational massive cores, and numerical simulations of collapsing massive cores. From the m…
Forming clusters within clusters: How 30 Doradus recollapsed and gave birth again
Daniel Rahner, Eric W. Pellegrini, Simon C. O. Glover +1
The 30 Doradus Nebula in the Large Magellanic Cloud (LMC) contains the massive starburst cluster NGC 2070 with a massive and probably younger stellar sub clump at its center: R136.…
