An Exploration of AGN and Stellar Feedback Effects in the Intergalactic Medium via the Low-redshift Lyα Forest [PDF]
The Astronomical Journal, 2023 We explore the role of galactic feedback on the low-redshift Ly α (Ly α ) forest ( z ≲ 2) statistics and its potential to alter the thermal state of the intergalactic medium. Using the Cosmology and Astrophysics with Machine Learning Simulations (CAMELS)

Modeling of the Effects of Stellar Feedback during Star Cluster Formation Using a Hybrid Gas and N-Body Method [PDF]
Astrophysical Journal, 2020 Understanding the formation of stellar clusters requires following the interplay between gas and newly formed stars accurately. We therefore couple the magnetohydrodynamics code FLASH to the N-body code ph4 and the stellar evolution code SeBa using the ...

Metallicity Gradients in Modern Cosmological Simulations. I. Tension between Smooth Stellar Feedback Models and Observations [PDF]
The Astrophysical JournalThe metallicity of galaxies, and its variation with galactocentric radius, provides key insights into the formation histories of galaxies and the physical processes driving their evolution.

SPICE: the connection between cosmic reionisation and stellar feedback in the first galaxies [PDF]
Monthly notices of the Royal Astronomical Society, 2023 We present SPICE, a new suite of radiation-hydrodynamic, cosmological simulations targeting the epoch of reionisation. The goal of these simulations is to systematically probe a variety of stellar feedback models, including ”bursty” and ”smooth” forms ...

Galactic coronae in Milky Way-like galaxies: the role of stellar feedback in gas accretion [PDF]
Monthly notices of the Royal Astronomical Society, 2023 Star-forming galaxies like the Milky Way are surrounded by a hot gaseous halo at the virial temperature – the so-called galactic corona – that plays a fundamental role in their evolution.

Stellar feedback in the star formation--gas density relation: Comparison between simulations and observations [PDF]
Astronomy & Astrophysics, 2023 The impact of stellar feedback on the Kennicutt-Schmidt (KS) law, which relates the star formation rate (SFR) to the surface gas density, is a topic of ongoing debate. The interpretation of high-resolution observations of individual clouds is challenging

Stellar feedback-regulated black hole growth: driving factors from nuclear to halo scales [PDF]
Monthly notices of the Royal Astronomical Society, 2022 Several recent simulations of galaxy formation predict two main phases of supermassive black hole (BH) accretion: an early, highly intermittent phase (during which BHs are under-massive relative to local scaling relations), followed by a phase of ...

Observational constraints on stellar feedback in dwarf galaxies [PDF]
Nature Astronomy, 2022 Feedback to the interstellar medium from ionizing radiation, stellar winds and supernovae is central to regulating star formation in galaxies. Owing to their low mass (

Determining the Timescale over Which Stellar Feedback Drives Turbulence in the Interstellar Medium: A Study of Four Nearby Dwarf Irregular Galaxies [PDF]
Astronomical Journal, 2022 Stellar feedback is fundamental to the modeling of galaxy evolution, as it drives turbulence and outflows in galaxies. Understanding the timescales involved are critical for constraining the impact of stellar feedback on the interstellar medium.
