The universal acceleration scale from stellar feedback

Monthly Notices of the Royal Astronomical Society Letters, 2020
It has been established for decades that rotation curves deviate from the Newtonian gravity expectation given baryons alone below a characteristic acceleration scale $g_{\dagger }\sim 10^{-8}\, \rm {cm\, s^{-2}}$, a scale promoted to a new fundamental ...

A Review of the Theory of Galactic Winds Driven by Stellar Feedback [PDF]

Galaxies, 2018
Galactic winds from star-forming galaxies are crucial to the process of galaxy formation and evolution, regulating star formation, shaping the stellar mass function and the mass-metallicity relation, and enriching the intergalactic medium with metals ...

X-Raying CAMELS: Constraining Baryonic Feedback in the Circumgalactic Medium with the CAMELS Simulations and eRASS X-Ray Observations

The Astrophysical Journal
The circumgalactic medium (CGM) around massive galaxies plays a crucial role in regulating star formation and feedback. Using the Cosmology and Astrophysics with MachinE Learning Simulations (CAMELS) suite, we develop emulators for the X-ray surface ...

The failure of stellar feedback, magnetic fields, conduction, and morphological quenching in maintaining red galaxies [PDF]

Monthly notices of the Royal Astronomical Society, 2018
The quenching ‘maintenance’ and related ‘cooling flow’ problems are important in galaxies from Milky Way mass through clusters. We investigate this in haloes with masses ∼$10^{12}\!-\!10^{14}\, {\rm M}_{\odot }$, using non-cosmological high-resolution ...

Tracing kinematic (mis)alignments in CALIFA merging galaxies : Stellar and ionized gas kinematic orientations at every merger stage [PDF]

, 2015
J.M.A. and V.W. acknowledge support from the European Research Council Starting Grant (SEDmorph; P.I. V. Wild).We present spatially resolved stellar and/or ionized gas kinematic properties for a sample of 103 interacting galaxies, tracing all merger ...

Star Cluster Formation in Cosmological Simulations. II. Effects of Star Formation Efficiency and Stellar Feedback [PDF]

Astrophysical Journal, 2017
The implementation of star formation and stellar feedback in cosmological simulations plays a critical role in shaping galaxy properties. In the first paper of the series, we presented a new method to model star formation as a collection of star clusters.

Bursting with Feedback: The Relationship between Feedback Model and Bursty Star Formation Histories in Dwarf Galaxies

The Astrophysical Journal
Due to their inability to self-regulate, ultrafaint dwarfs are sensitive to prescriptions in subgrid physics models that converge and regulate at higher masses.

Does Feedback from Supermassive Black Holes Coevolve with the Host in Type 2 Quasars?

The Astrophysical Journal, 2023
The feedback from the accretion of central supermassive black holes (SMBHs) is a hot topic in the coevolution of SMBHs and their host galaxies. By tracing the large-scale outflow using the line profile and bulk velocity shift of [O iii ] λ 5007, the ...

Physical properties and scaling relations of molecular clouds: the effect of stellar feedback [PDF]

Monthly notices of the Royal Astronomical Society, 2018
Using hydrodynamical simulations of entire galactic discs similar to the Milky Way (MW), reaching 4.6{ pc} resolution, we study the origins of observed physical properties of giant molecular clouds (GMCs).

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.
