Star clusters across cosmic time

MR Krumholz, CF McKee… - Annual Review of …, 2019 - annualreviews.org
Star clusters stand at the intersection of much of modern astrophysics: the ISM, gravitational
dynamics, stellar evolution, and cosmology. Here, we review observations and theoretical …

Globular cluster formation and evolution in the context of cosmological galaxy assembly: open questions

DA Forbes, N Bastian, M Gieles… - … of the Royal …, 2018 - royalsocietypublishing.org
We discuss some of the key open questions regarding the formation and evolution of

FIRE-3: updated stellar evolution models, yields, and microphysics and fitting functions for applications in galaxy simulations

PF Hopkins, A Wetzel, C Wheeler… - Monthly Notices of …, 2023 - academic.oup.com
Increasingly, uncertainties in predictions from galaxy formation simulations (at sub-Milky
Way masses) are dominated by uncertainties in stellar evolution inputs. In this paper, we …

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
(IMF). The IMF is observed to be nearly universal in the Milky Way and its satellites, and …

The diversity and variability of star formation histories in models of galaxy evolution

KG Iyer, S Tacchella, S Genel… - Monthly Notices of …, 2020 - academic.oup.com
Understanding the variability of galaxy star formation histories (SFHs) across a range of time-
scales provides insight into the underlying physical processes that regulate star formation …

STARFORGE: the effects of protostellar outflows on the IMF

D Guszejnov, MY Grudić, PF Hopkins… - Monthly Notices of …, 2021 - academic.oup.com
The initial mass function (IMF) of stars is a key quantity affecting almost every field of
astrophysics, yet it remains unclear what physical mechanisms determine it. We present the …

Self-consistent proto-globular cluster formation in cosmological simulations of high-redshift galaxies

zoom-in simulations of z≥ 5 galaxies from the Feedback In Realistic Environments project …

First predicted cosmic ray spectra, primary-to-secondary ratios, and ionization rates from MHD galaxy formation simulations

PF Hopkins, IS Butsky, GV Panopoulou… - Monthly Notices of …, 2022 - academic.oup.com
We present the first simulations evolving resolved spectra of cosmic rays (CRs) from MeV–
TeV energies (including electrons, positrons,(anti) protons, and heavier nuclei), in live …

Radiative stellar feedback in galaxy formation: Methods and physics

PF Hopkins, MY Grudić, A Wetzel… - Monthly Notices of …, 2020 - academic.oup.com
Radiative feedback (RFB) from stars plays a key role in galaxies, but remains poorly
understood. We explore this using high-resolution, multifrequency radiation-hydrodynamics …
