“Hierarchical Star Formation in the Large Magellanic Cloud”
Abstract:
The VISTA Magellanic Clouds Survey (VMC) is a near-infrared survey of the Magellanic system. The VMC data has been exploited to detect and study statistically correlated young groups of stars — also known as “young stellar structures” — in the Large and Small Magellanic Clouds (LMC and SMC). We showcase the ~2500 recently detected young stellar structures in the LMC and their similarity to the fractal interstellar medium. Our results indicate that the fractal nature of the young stellar structures has been inherited from the gas clouds from which they form and that this architecture is generated by turbulence. Our results also suggest that star formation in the LMC is scale-free from 10 pc to 700 pc.
