Does supernova feedback regulate the star formation rate in dwarf galaxies?
D. Whitworth, E. Vázquez-Semadeni, J. Ballesteros-Paredes +1
Stars form in cold, dense clouds embedded in galactic discs, but whether their formation is primarily regulated by gravitational collapse, turbulence, or stellar feedback remains u…
Effect of gravity-driven longitudinal flows in filaments on angular momentum transport to embedded cores
Griselda Arroyo-Chávez, Shuo Kong, Enrique Vázquez-Semadeni
Different models of filament formation predict distinct patterns of angular momentum redistribution toward embedded cores, set by the underlying velocity-field structure, which can…
The ALMA-QUARKS Survey: Discovery of Dusty Fibrils inside Massive Star-forming Clumps
Yan-Kun Zhang, Tie Liu, Wenyu Jiao +35
We report the discovery of more than 323 superfine dusty filamentary structures (fibrils) inside 121 massive star forming clumps that are located in widely different Galactic envir…
What is the contribution of gravitational infall on the mass assembly of star-forming clouds? A case study in a numerical simulation of the interstellar medium
Noé Brucy, Enrique Vázquez-Semadeni, Tine Colman +2
Star formation in galaxies is a complex phenomenon occurring on a very wide range of scales, and molecular clouds are at the heart of this process. The formation of these structure…
