Gravity or turbulence? VII. The Schmidt-Kennicutt law, the star formation efficiency, and the mass density of clusters from gravitational collapse rather than turbulent support
Manuel Zamora-Aviles, Vianey Camacho, Javier Ballesteros-Paredes +7
We explore the Schmidt-Kennicutt (SK) relations and the star formation efficiency per free-fall time (), mirroring observational studies, in numerical simulations of f…

The Turbulent Support (TS) and Global Hierarchical Collapse (GHC) models for molecular clouds compared. Differences, convergence, and myths
Enrique Vázquez-Semadeni, Aina Palau, Gilberto C. Gómez +8
We provide a detailed comparison between the ``turbulent support'' (TS) and ``global hierarchical collapse'' (GHC) models for molecular clouds and star formation, their respective…

The role of shocks and the velocity gradient in the relative orientation of the magnetic field and dense gas clouds
Guido Granda-Muñoz, Enrique Vázquez-Semadeni, Gilberto C. Gómez
We investigate the alignment mechanism between the magnetic field and interstellar clouds formed by the collision of warm atomic gas. We find that the magnetic field, initially ori…
