The external photoevaporation of planet-forming discs

AJ Winter, TJ Haworth - The European Physical Journal Plus, 2022 - Springer
Planet-forming disc evolution is not independent of the star formation and feedback process
in giant molecular clouds. In particular, OB stars emit UV radiation that heats and disperses …

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 …

Pre-supernova feedback mechanisms drive the destruction of molecular clouds in nearby star-forming disc galaxies

M Chevance, JMD Kruijssen… - Monthly Notices of …, 2022 - academic.oup.com
It is a major open question which physical processes stop gas accretion on to giant
molecular clouds (GMCs) and limit the efficiency at which gas is converted into stars. While …

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 …

Simulating ionization feedback from young massive stars: impact of numerical resolution

Y Deng, H Li, R Kannan, A Smith… - Monthly Notices of …, 2024 - academic.oup.com
Modelling galaxy formation in hydrodynamic simulations has increasingly adopted various
radiative transfer methods to account for photoionization feedback from young massive …

The physics of Lyman-α escape from disc-like galaxies

A Smith, R Kannan, S Tacchella… - Monthly Notices of …, 2022 - academic.oup.com
Hydrogen emission lines can provide extensive information about star-forming galaxies in
both the local and high-redshift Universe. We present a detailed Lyman continuum (LyC) …

The Radcliffe Wave is oscillating

R Konietzka, AA Goodman, C Zucker, A Burkert… - Nature, 2024 - nature.com
Our Sun lies within 300 parsecs of the 2.7-kiloparsecs-long sinusoidal chain of dense gas
clouds known as the Radcliffe Wave. The structure's wave-like shape was discovered using …

PHANGS–JWST First Results: Multiwavelength View of Feedback-driven Bubbles (the Phantom Voids) across NGC 628

AT Barnes, EJ Watkins, SE Meidt… - The Astrophysical …, 2023 - iopscience.iop.org
We present a high-resolution view of bubbles within the Phantom Galaxy (NGC 628), a
nearby (∼ 10 Mpc), star-forming (∼ 2 M⊙ yr− 1), face-on (i∼ 9) grand-design spiral galaxy …

Empirically motivated early feedback: momentum input by stellar feedback in galaxy simulations inferred through observations

BW Keller, JMD Kruijssen… - Monthly Notices of the …, 2022 - academic.oup.com
We present a novel method for including the effects of early (pre-supernova) feedback in
simulations of galaxy evolution. Rather than building a model which attempts to match …

Pre-supernova feedback sets the star cluster mass function to a power law and reduces the cluster formation efficiency

EP Andersson, MM Mac Low, O Agertz… - Astronomy & …, 2024 - aanda.org
Context. The star cluster initial mass function is observed to have an inverse power law
exponent around 2, yet there is no consensus on what determines this distribution, and why …
