Stellar feedback-regulated black hole growth: driving factors from nuclear to halo scales [PDF]
, 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 accelerated growth.

Impact of galactic shear and stellar feedback on star formation [PDF]
Astronomy & Astrophysics, 2018 Context. Feedback processes and the galactic shear regulate star formation. Aims. We investigate the effects of differential galactic rotation and stellar feedback on the interstellar medium (ISM) and on the star formation rate (SFR). Methods. A numerical shearing box is used to perform three-dimensional simulations of a 1 kpc stratified cubic box of ...

Numerical Simulations of High Redshift Star Formation in Dwarf Galaxies [PDF]
, 2002 We present first results from three-dimensional hydrodynamic simulations of the high redshift formation of dwarf galaxies. The simulations use an Eulerian adaptive mesh refinement technique to follow the non-equilibrium chemistry of hydrogen and helium ...

FEEDBACK: a SOFIA Legacy Program to Study Stellar Feedback in Regions of Massive Star Formation [PDF]
Publications of the Astronomical Society of the Pacific, 2020 FEEDBACK is a SOFIA legacy program dedicated to study the interaction of massive stars with their environment. It performs a survey of 11 galactic high mass star forming regions in the 158 $ $m (1.9 THz) line of CII and the 63 $ $m (4.7 THz) line of OI.

Galactic chimney sweeping: the effect of 'gradual' stellar feedback mechanisms on the evolution of dwarf galaxies [PDF]
, 2019 We investigate the impact of time-resolved `gradual' stellar feedback processes in high redshift dwarf spheroidal galaxies. Here `gradual' feedback refers to individual stellar feedback events which deposit energy over a period of time. We conduct high resolution hydrodynamical simulations of dwarf spheroidal galaxies with halo masses of 10$^7$ M$_ ...

An Exploration of AGN and Stellar Feedback Effects in the Intergalactic Medium via the Low Redshift Lyman-$α$ Forest [PDF]
arXiv, 2023 We explore the role of galactic feedback on the low redshift Lyman-$\alpha$ (Ly$\alpha$)~forest ($z \lesssim 2$) statistics and its potential to alter the thermal state of the intergalactic medium. Using the Cosmology and Astrophysics with Machine Learning Simulations (CAMELS) suite, we explore variations of the AGN and stellar feedback models in the ...

The impact of episodic outflow feedback on stellar multiplicity and the star formation efficiency [PDF]
, 2020 The accretion of material onto young protostars is accompanied by the launching of outflows. Observations show that accretion, and therefore also outflows, are episodic. However, the effects of episodic outflow feedback on the core-scale are not well understood.

The Role of Black Hole Feedback on Size and Structural Evolution in Massive Galaxies
, 2018 We use cosmological hydrodynamical simulations to investigate the role of feedback from accreting black holes on the evolution of sizes, compactness, stellar core density and specific star-formation of massive galaxies with stellar masses of $ M_{star} >

The degeneracy between star-formation parameters in dwarf galaxy simulations and the Mstar-Mhalo relation [PDF]
, 2012 We present results based on a set of N-Body/SPH simulations of isolated dwarf galaxies. The simulations take into account star formation, stellar feedback, radiative cooling and metal enrichment.
