The energy and dynamics of trapped radiative feedback with stellar winds

open access: yesMonthly Notices of the Royal Astronomical Society, 2023
ABSTRACT In this paper, we explore the significant, non-linear impact that stellar winds have on H ii regions. We perform a parameter study using three-dimensional radiative magnetohydrodynamic simulations of wind and ultraviolet radiation feedback from a 35 M⊙ star formed self-consistently in a turbulent, self-gravitating cloud, similar

Stellar Feedback and Resolved Stellar IFU Spectroscopy in the Nearby Spiral Galaxy NGC 300 [PDF]

open access: yesThe Astrophysical Journal, 2020
Abstract We present MUSE integral field unit (IFU) observations of five individual H ii regions in two giant star-forming complexes in the low-metallicity, nearby dwarf spiral galaxy NGC 300. In combination with high spatial resolution Hubble Space Telescope photometry, we demonstrate the extraction of stellar spectra and classification ...

Modeling for Stellar Feedback in Galaxy Formation Simulations [PDF]

open access: yesThe Astrophysical Journal, 2017
Abstract Various heuristic approaches to model unresolved supernova (SN) feedback in galaxy formation simulations exist to reproduce the formation of spiral galaxies and the overall inefficient conversion of gas into stars. Some models, however, require resolution-dependent scalings.

Formation of Massive and Wide First-star Binaries in Radiation Hydrodynamic Simulations

open access: yesThe Astrophysical Journal, 2023
We study the formation of Population III stars by performing radiation hydrodynamic simulations for three different initial clouds extracted from cosmological hydrodynamic simulations.

Where Did the Outskirts Go? Outer Stellar Haloes as a Sensitive Probe of Supernova Feedback [PDF]

open access: yes, 2021
A recent comparison by Merritt et al. 2020 of simulated and observed Milky Way-mass galaxies has identified a significant tension between the outskirts ($r>20\kpc$) of the stellar halos in simulated and observed galaxies. Using observations from the Dragonfly telescope and simulated galaxies from the Illustris-TNG100 project, Merritt et al.

A Systematic Look at the Effects of Radiative Feedback on Disc Galaxy Formation [PDF]

open access: yes, 2014
Galaxy formation models and simulations rely on various feedback mechanisms to reproduce the observed baryonic scaling relations and galaxy morphologies. Although dwarf galaxy and giant elliptical properties can be explained using feedback from supernova

Theoretical Re-evaluations of Scaling Relations between SMBHs and Their Host Galaxies–2. Importance of AGN Feedback Suggested by Stellar Age–Velocity Dispersion Relation

open access: yesFrontiers in Astronomy and Space Sciences, 2017
We present the galactic stellar age—velocity dispersion relation obtained from a semi-analytic model of galaxy formation. We divide galaxies into two populations: galaxies which have over-massive/under-massive black holes (BHs) against the best-fitting ...
