The life and times of giant molecular clouds

M Chevance, MR Krumholz, AF McLeod… - arXiv preprint arXiv …, 2022 - arxiv.org
Giant molecular clouds (GMCs) are the sites of star formation and stellar feedback in
galaxies. Their properties set the initial conditions for star formation and their lifecycles …

Effects of the environment and feedback physics on the initial mass function of stars in the STARFORGE simulations

D Guszejnov, MY Grudić, SSR Offner… - Monthly Notices of …, 2022 - academic.oup.com
One of the key mysteries of star formation is the origin of the stellar initial mass function

Cluster assembly and the origin of mass segregation in the STARFORGE simulations

D Guszejnov, C Markey, SSR Offner… - Monthly Notices of …, 2022 - academic.oup.com
Stars form in dense, clustered environments, where feedback from newly formed stars
eventually ejects the gas, terminating star formation and leaving behind one or more star …
