Star formation lies at the center of a web of processes that drive cosmic evolution:
generation of radiant energy, synthesis of elements, formation of planets, and development …

Whether the stellar initial mass function (IMF) is universal or is instead sensitive to
environmental conditions is of critical importance: The IMF influences most observable …

Theoretical modeling of massive stars predicts a gap in the black hole (BH) mass function
above∼ 40–50 M⊙ for BHs formed through single star evolution, arising from (pulsational) …

We report the statistical properties of stars, brown dwarfs and multiple systems obtained from
the largest radiation hydrodynamical simulation of star cluster formation to date that resolves …

Spectroscopic analyses of hydrogen-rich WN 5–6 stars within the young star clusters NGC
3603 and R136 are presented, using archival Hubble Space Telescope and Very Large …

The current knowledge on the stellar IMF is documented. It is usually described as being
invariant, but evidence to the contrary has emerged: it appears to become top-heavy when …

Reionization in the early Universe is likely driven by dwarf galaxies. Using cosmological
radiation-hydrodynamic simulations, we study star formation and the escape of Lyman …

Residual-gas expulsion after cluster formation has recently been shown to leave an imprint
in the low-mass present-day stellar mass function (PDMF) which allowed the estimation of …

The stellar initial mass function (IMF) is commonly assumed to be an invariant probability
density distribution function of initial stellar masses. These initial stellar masses are …

What else can be said about star formation rate indicators that has not been said already
many times over? The 'coming of age'of large groundbased surveys and the unprecedented …
