Confronting feedback simulations with observations of hot gas in elliptical galaxies [PDF]
, 2009 Elliptical galaxies comprise primarily old stars, which collectively generate a long-lasting feedback via stellar mass-loss and Type Ia SNe. This feedback can be traced by X-ray-emitting hot gas in and around such galaxies, in which little cool gas is ...

A fundamental test for stellar feedback recipes in galaxy simulations [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 Direct comparisons between galaxy simulations and observations that both reach scales < 100 pc are strong tools to investigate the cloud-scale physics of star formation and feedback in nearby galaxies. Here we carry out such a comparison for hydrodynamical simulations of a Milky Way-like galaxy, including stochastic star formation, HII region and ...

Bursty Star Formation in Dwarfs is Sensitive to Numerical Choices in Supernova Feedback Models
The Astrophysical JournalSimulations of galaxy formation are mostly unable to resolve the energy-conserving phase of individual supernova events, having to resort to subgrid models to distribute the energy and momentum resulting from stellar feedback.

Discovery of a New Molecular Bubble–Outflow Structure in the Taurus B18 Cloud
The Astrophysical Journal, 2023 Star formation can produce bubbles and outflows, as a result of stellar feedback. Outflows and bubbles inject momentum and energy into the surrounding interstellar medium, and so are related to the overall energy balance of the molecular cloud. Molecular

The Impact of Feedback on Disk Galaxy Scaling Relations
, 2009 We use a disk galaxy evolution model to investigate the impact of mass outflows (a.k.a. feedback) on disk galaxy scaling relations. Our model follows the accretion, cooling, star formation and ejection of baryonic mass inside growing dark matter haloes ...

Exploring the Evolution of a Dwarf Spheroidal Galaxy with SPH Simulations. II. AGN Feedback
The Astrophysical JournalWe investigate active galactic nucleus (AGN) feedback from an intermediate-mass black hole at the center of a dwarf spheroidal galaxy, by performing isolated galaxy simulations using a modified version of the GADGET-3 code. We consider Leo II (PGC 34176)

Sources of X-rays from galaxies [PDF]
, 2011 Galactic X-ray emission is a manifestation of various high-energy phenomena and processes. The brightest X-ray sources are typically accretion-powered objects: active galactic nuclei and low- or high-mass X-ray binaries.
