Baryonic solutions and challenges for cosmological models of dwarf galaxies

LV Sales, A Wetzel, A Fattahi - Nature Astronomy, 2022 - nature.com
Galaxies and their dark-matter haloes have posed several challenges to the dark energy
plus cold dark matter (Λ CDM) cosmological model. These discrepancies between …

Cool outflows in galaxies and their implications

S Veilleux, R Maiolino, AD Bolatto, S Aalto - The Astronomy and …, 2020 - Springer
Neutral-atomic and molecular outflows are a common occurrence in galaxies, near and far.
They operate over the full extent of their galaxy hosts, from the innermost regions of galactic …

A survey of high-z galaxies: serra simulations

A Pallottini, A Ferrara, S Gallerani… - Monthly Notices of …, 2022 - academic.oup.com
We introduce serra, a suite of zoom-in high-resolution (, at z= 7.7) cosmological simulations
including non-equilibrium chemistry and on-the-fly radiative transfer. The outputs are post …

The dynamics and outcome of star formation with jets, radiation, winds, and supernovae in concert

MY Grudić, D Guszejnov, SSR Offner… - Monthly Notices of …, 2022 - academic.oup.com

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 …

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 rapid onset of stellar bars in the baryon-dominated centers of disk galaxies

J Bland-Hawthorn, T Tepper-Garcia… - The Astrophysical …, 2023 - iopscience.iop.org
Recent observations of high-redshift galactic disks (z≈ 1–3) show a strong negative trend in
the dark-matter (DM) fraction f DM with increasing baryon surface density. For this to be true …

No missing photons for reionization: moderate ionizing photon escape fractions from the FIRE-2 simulations
