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 …

Theoretical challenges in galaxy formation

T Naab, JP Ostriker - Annual review of astronomy and …, 2017 - annualreviews.org
Numerical simulations have become a major tool for understanding galaxy formation and
evolution. Over the decades the field has made significant progress. It is now possible to …

What causes the formation of discs and end of bursty star formation?

PF Hopkins, AB Gurvich, X Shen… - Monthly Notices of …, 2023 - academic.oup.com
As they grow, galaxies can transition from irregular/spheroidal with 'bursty'star formation
histories (SFHs), to discy with smooth SFHs. But even in simulations, the direct physical …

Fast and inefficient star formation due to short-lived molecular clouds and rapid feedback

JMD Kruijssen, A Schruba, M Chevance, SN Longmore… - Nature, 2019 - nature.com
The physics of star formation and the deposition of mass, momentum and energy into the
interstellar medium by massive stars ('feedback') are the main uncertainties in modern …

The structure of multiphase galactic winds

DB Fielding, GL Bryan - The Astrophysical Journal, 2022 - iopscience.iop.org
We present a novel analytic framework to model the steady-state structure of multiphase
galactic winds comprised of a hot, volume-filling component and a cold, clumpy component …

Pressure-regulated, feedback-modulated star formation in disk galaxies

EC Ostriker, CG Kim - The Astrophysical Journal, 2022 - iopscience.iop.org
The star formation rate (SFR) in galactic disks depends on both the quantity of the available
interstellar medium (ISM) gas and its physical state. Conversely, the ISM's physical state …

The SPHINX cosmological simulations of the first billion years: the impact of binary stars on reionization

J Rosdahl, H Katz, J Blaizot, T Kimm… - Monthly Notices of …, 2018 - academic.oup.com
We present the sphinx suite of cosmological adaptive mesh refinement simulations, the first
radiation-hydrodynamical simulations to simultaneously capture large-scale reionization …

A tale of two DIGs: The relative role of H II regions and low-mass hot evolved stars in powering the diffuse ionised gas (DIG) in PHANGS–MUSE galaxies

F Belfiore, F Santoro, B Groves, E Schinnerer… - Astronomy & …, 2022 - aanda.org
We use integral field spectroscopy from the PHANGS–MUSE survey, which resolves the
ionised interstellar medium structure at∼ 50 pc resolution in 19 nearby spiral galaxies, to …

Efficiently Cooled Stellar Wind Bubbles in Turbulent Clouds. I. Fractal Theory and Application to Star-forming Clouds

L Lancaster, EC Ostriker, JG Kim… - The Astrophysical …, 2021 - iopscience.iop.org
Winds from massive stars have velocities of 1000 km s− 1 or more and produce hot, high-
pressure gas when they shock. We develop a theory for the evolution of bubbles driven by …

The physical nature of starburst-driven galactic outflows

EE Schneider, EC Ostriker, BE Robertson… - The Astrophysical …, 2020 - iopscience.iop.org
We present the fourth simulation of the Cholla Galactic OutfLow Simulations suite. Using a
physically motivated prescription for clustered supernova feedback, we successfully drive a …
