Bursting with Feedback: The Relationship between Feedback Model and Bursty Star Formation Histories in Dwarf Galaxies
Bianca Azartash-Namin, Anna Engelhardt, Ferah Munshi +6
We use high-resolution cosmological simulations to compare the effect of bursty star formation histories on dwarf galaxy structure for two different subgrid supernovae (SNe) feedba…
HI discs of L galaxies as probes of the baryonic physics of galaxy evolution
Jindra Gensior, Robert Feldmann, Marta Reina-Campos +7
Understanding what shapes the cold gas component of galaxies, which both provides the fuel for star formation and is strongly affected by the subsequent stellar feedback, is a cruc…
Bringing Stellar Evolution & Feedback Together: Summary of proposals from the Lorentz Center Workshop, 2022
Sam Geen, Poojan Agrawal, Paul A. Crowther +34
Stars strongly impact their environment, and shape structures on all scales throughout the universe, in a process known as ``feedback''. Due to the complexity of both stellar evolu…
Can Cosmological Simulations Reproduce the Spectroscopically Confirmed Galaxies Seen at ?
B. W. Keller, F. Munshi, M. Trebitsch +1
Recent photometric detections of extreme redshift galaxies from the JWST have been shown to be in strong tension with existing simulation models for galaxy formation, and…
PHANGS-JWST First Results: Multi-wavelength view of feedback-driven bubbles (The Phantom Voids) across NGC 628
Ashley T. Barnes, Elizabeth J. Watkins, Sharon E. Meidt +51
We present a high-resolution view of bubbles within The Phantom Galaxy (NGC 628); a nearby (~10Mpc), star-forming (~2Msun/yr), face-on (i~9deg) grand-design spiral galaxy. With new…
PHANGS-JWST First Results: A statistical view on bubble evolution in NGC628
Elizabeth J. Watkins, Ashley Barnes, Kiana F. Henny +49
The first JWST observations of nearby galaxies have unveiled a rich population of bubbles that trace the stellar feedback mechanisms responsible for their creation. Studying these…
Empirically-motivated early feedback: momentum input by stellar feedback in galaxy simulations inferred through observations
Benjamin W. Keller, J. M. Diederik Kruijssen, Mélanie Chevance
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 ideal…
Introducing EMP-Pathfinder: modelling the simultaneous formation and evolution of stellar clusters in their host galaxies
Marta Reina-Campos, Benjamin W. Keller, J. M. Diederik Kruijssen +5
The formation and evolution of stellar clusters is intimately linked to that of their host galaxies. To study this connection, we present the EMP-Pathfinder suite of cosmological z…
Not the Birth Cluster: the Stellar Clustering that Shapes Planetary Systems is Generated by Galactic-Dynamical Perturbations
J. M. Diederik Kruijssen, Steven N. Longmore, Mélanie Chevance +4
Recent work has demonstrated that exoplanetary system properties correlate strongly with ambient stellar clustering in six-dimensional stellar position-velocity phase space, quanti…
Momentum feedback from marginally-resolved HII regions in isolated disc galaxies
Sarah M. R. Jeffreson, Mark R. Krumholz, Yusuke Fujimoto +4
We present a novel, physically-motivated sub-grid model for HII region feedback within the moving mesh code Arepo, accounting for both the radiation pressure-driven and thermal exp…
A scaling relation for the molecular cloud lifetime in Milky Way-like galaxies
Sarah M. R. Jeffreson, Benjamin W. Keller, Andrew J. Winter +4
We study the time evolution of molecular clouds across three Milky Way-like isolated disc galaxy simulations at a temporal resolution of 1 Myr, and at a range of spatial resolution…
Where Did the Outskirts Go? Outer Stellar Haloes as a Sensitive Probe of Supernova Feedback
B. W. Keller
A recent comparison by Merritt et al. 2020 of simulated and observed Milky Way-mass galaxies has identified a significant tension between the outskirts ($r>20\kpc$) of the stellar…
Properties of Compact Faint Radio Sources as a Function of Angular Size from Stacking
Ryan S. Johnston, Jeroen M. Stil, Ben W. Keller
The polarization properties of radio sources powered by an Active Galactic Nucleus (AGN) have attracted considerable attention because of the significance of magnetic fields in the…
Pre-supernova feedback mechanisms drive the destruction of molecular clouds in nearby star-forming disc galaxies
Mélanie Chevance, J. M. Diederik Kruijssen, Mark R. Krumholz +28
It is a major open question which physical processes stop the accretion of gas onto giant molecular clouds (GMCs) and limit the efficiency at which gas is converted into stars with…
Constraining the formation of NGC1052-DF2 from its unusual globular cluster population
Sebastian Trujillo-Gomez, J. M. Diederik Kruijssen, Benjamin W. Keller +1
The ultra-diffuse galaxy (UDG) NGC1052-DF2 has a low dark matter content and hosts a very unusual globular cluster (GC) population, with a median luminosity times higher th…
The baryon cycle of Seven Dwarfs with superbubble feedback
Mattia Mina, Sijing Shen, Benjamin Walter Keller +3
We present results from a high-resolution, cosmological, CDM simulation of a group of field dwarf galaxies with the "superbubble" model for clustered SN feedback, accounting for…
Where did the globular clusters of the Milky Way form? Insights from the E-MOSAICS simulations
Benjamin W. Keller, J. M. Diederik Kruijssen, Joel Pfeffer +5
Globular clusters (GCs) are typically old, with most having formed at z >~ 2. This makes understanding their birth environments difficult, as they are typically too distant to obse…
The kinematics of globular cluster populations in the E-MOSAICS simulations and their implications for the assembly history of the Milky Way
Sebastian Trujillo-Gomez, J. M. Diederik Kruijssen, Marta Reina-Campos +5
We present a detailed comparison of the Milky Way (MW) globular cluster (GC) kinematics with the 25 Milky Way-mass cosmological simulations from the E-MOSAICS project. While the MW…
Uncertainties in supernova input rates drive qualitative differences in simulations of galaxy evolution
Benjamin W. Keller, J. M. Diederik Kruijssen
Feedback from core collapse supernovae (SNe), the final stage of evolution of massive stars, is a key element in galaxy formation theory. The energy budget of SN feedback, as well…
Heart of Darkness: the influence of galactic dynamics on quenching star formation in galaxy spheroids
Jindra Gensior, J. M. Diederik Kruijssen, Benjamin W. Keller
Quenched galaxies are often observed to contain a strong bulge component. The key question is whether this reflects a causal connection - can star formation be quenched dynamically…
