Effects of initial density profiles on massive star cluster formation in giant molecular clouds

  title={Effects of initial density profiles on massive star cluster formation in giant molecular clouds},
  author={Ying-Tung Chen and Hui Li and Mark Vogelsberger},
  journal={Monthly Notices of the Royal Astronomical Society},
We perform a suite of hydrodynamic simulations to investigate how initial density profiles of giant molecular clouds (GMCs) affect their subsequent evolution. We find that the star formation duration and integrated star formation efficiency of the whole clouds are not sensitive to the choice of different profiles but are mainly controlled by the interplay between gravitational collapse and stellar feedback. Despite this similarity, GMCs with different profiles show dramatically different modes… Expand

A parallel non-uniform fast Fourier transform library based on an "exponential of semicircle" kernel
FINUFFT is presented, an efficient parallel library for type 1 (nonuiform to uniform), type 2 (uniform to nonuniform), or type 3 (non uniform toNonuniform) transforms, in dimensions 1, 2, or 3, which uses minimal RAM, requires no precomputation or plan steps, and has a simple interface to several languages.
