The first stars: formation, properties, and impact

RS Klessen, SCO Glover - Annual Review of Astronomy and …, 2023 - annualreviews.org
The first generation of stars, often called Population III (or Pop III), form from metal-free
primordial gas at redshifts z∼ 30 and below. They dominate the cosmic star-formation …

Photodissociation and X-Ray-Dominated Regions

MG Wolfire, L Vallini, M Chevance - Annual Review of …, 2022 - annualreviews.org
The radiation from stars and active galactic nuclei (AGNs) creates photodissociation regions

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 …

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 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 …

PHANGS–JWST First Results: A Statistical View on Bubble Evolution in NGC 628

EJ Watkins, AT Barnes, K Henny, H Kim… - The Astrophysical …, 2023 - iopscience.iop.org
The first JWST observations of nearby galaxies have unveiled a rich population of bubbles

Efficiently Cooled Stellar Wind Bubbles in Turbulent Clouds. II. Validation of Theory with Hydrodynamic Simulations

L Lancaster, EC Ostriker, JG Kim… - The Astrophysical …, 2021 - iopscience.iop.org
In a companion paper, we develop a theory for the evolution of stellar wind-driven bubbles
in dense, turbulent clouds. This theory proposes that turbulent mixing at a fractal …

Introducing TIGRESS-NCR. I. Coregulation of the Multiphase Interstellar Medium and Star Formation Rates

CG Kim, JG Kim, M Gong… - The Astrophysical …, 2023 - iopscience.iop.org
Massive, young stars are the main source of energy that maintains multiphase structure and
turbulence in the interstellar medium (ISM), and without this" feedback" the star formation …

Comparing the pre-SNe feedback and environmental pressures for 6000 H ii regions across 19 nearby spiral galaxies

AT Barnes, SCO Glover, K Kreckel… - Monthly Notices of …, 2021 - academic.oup.com
The feedback from young stars (ie pre-supernova) is thought to play a crucial role in
molecular cloud destruction. In this paper, we assess the feedback mechanisms acting …

Quantifying the energetics of molecular superbubbles in PHANGS galaxies

EJ Watkins, K Kreckel, B Groves, SCO Glover… - Astronomy & …, 2023 - aanda.org
