Effects of Stellar Feedback on Stellar and Gas Kinematics of Star-forming Galaxies at 0.6 < z < 1.0 [PDF]

, 2020
Recent zoom-in cosmological simulations have shown that stellar feedback can flatten the inner density profile of the dark matter halo in low-mass galaxies.

Stellar feedback from high-mass X-ray binaries in cosmological hydrodynamical simulations [PDF]

, 2015
We explored the role of X-ray binaries composed by a black hole and a massive stellar companion [black hole X-ray binaries (BHXs)] as sources of kinetic feedback by using hydrodynamical cosmological simulations.

Galaxies on FIRE (Feedback In Realistic Environments): stellar feedback explains cosmologically inefficient star formation [PDF]

, 2014
We present a series of high-resolution cosmological simulations of galaxy formation to z = 0, spanning halo masses ∼10^8–10^(13) M⊙, and stellar masses ∼10^4–10^(11) M⊙.

The Answer, My Friend, is Blowing in the Stellar Wind: The Impact of Early Stellar Feedback on the Interstellar Medium

, 2020
The mechanism of stellar feedback -- a star's injection of mass, energy, and momentum into the interstellar medium (ISM) -- not only plays a key role in moderating star formation at the parsec scale, but is also thought to impact galactic mass and ...

Delayed Massive-star Mechanical Feedback at Low Metallicity

The Astrophysical Journal, 2023
The classical model of massive-star mechanical feedback is based on effects at solar metallicity ( Z _⊙ ), yet feedback parameters are very different at low metallicity.

The effect of stellar and AGN feedback on the low redshift Lyman-α forest in the Sherwood simulation suite [PDF]

, 2017
We study the effect of different feedback prescriptions on the properties of the low redshift (z ≤ 1.6) Ly α forest using a selection of hydrodynamical simulations drawn from the Sherwood simulation suite.

Linking stellar populations to H II regions across nearby galaxies [PDF]

, 2022
Context. Stellar feedback is one of the fundamental factors regulating the evolution of galaxies. However, we still do not have access to strong observational constraints on the relative importance of the different feedback mechanisms (e.g.

How stellar feedback simultaneously regulates star formation and drives outflows

, 2017
Stellar-feedback-driven outflows are thought to be a crucial process in galaxy formation, but our physical understanding of them is still rudimentary. I will present an analytical model for how stellar feedback simultaneously regulates star formation and

Velocity dispersion functions of pressure-supported galaxies in EAGLE simulations with varying active galactic nucleus feedback

Astronomy & Astrophysics
We investigated the stellar velocity dispersion functions (VDFs) of pressure-supported galaxies in the EAGLE cosmological simulations. The central stellar velocity dispersion is one of the fundamental dynamical tracers of the total mass of galaxy ...
