Towards a complete accounting of energy and momentum from stellar feedback in galaxy formation simulations [PDF]
Stellar feedback plays a key role in galaxy formation by regulating star formation, driving interstellar turbulence and generating galactic scale outflows. Although modern simulations of galaxy formation can resolve scales of 10-100 pc, star formation and feedback operate on smaller, "subgrid" scales.

Star Formation in Disk Galaxies. III. Does stellar feedback result in cloud death? [PDF]
Stellar feedback, star formation and gravitational interactions are major controlling forces in the evolution of Giant Molecular Clouds (GMCs). To explore their relative roles, we examine the properties and evolution of GMCs forming in an isolated galactic disk simulation that includes both localised thermal feedback and photoelectric heating.

Effects of stellar feedback on cores in STARFORGE [PDF]
Stars form in dense cores within molecular clouds and newly formed stars influence their natal environments. How stellar feedback impacts core properties and evolution is subject to extensive investigation. We performed a hierarchical clustering (dendrogram) analysis of a STARFORGE simulation modelling a giant molecular cloud to identify gas ...

Kinematics of Young Stellar Objects under Various Stellar Feedback
Based on the Gaia Data Release 3 and APOGEE data sets, we investigate the kinematic differences between young stellar objects (YSOs) and their parent clouds in five nearby star-forming regions.

The role of Stellar Feedback in the formation of galactic disks and bulges in a LCDM Universe [PDF]
Although supernova explosions and stellar winds happens at scales bellow 100 pc, they affect the interstellar medium(ISM) and galaxy formation. We use cosmological N-body+Hydrodynamics simulations of galaxy formation, as well as simulations of the ISM to study the effect of stellar feedback on galactic scales.

What Is the Role of Stellar Radiative Feedback in Setting the Stellar Mass Spectrum? [PDF]
Abstract In spite of decades of theoretical efforts, the physical origin of the stellar initial mass function (IMF) is still debated. Particularly crucial is the question of what sets the peak of the distribution. To investigate this issue, we perform high-resolution numerical simulations with radiative feedback exploring, in particular,

Delayed Massive-star Mechanical Feedback at Low Metallicity [PDF]
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.

Feedback from galactic stellar bulges and hot gaseous haloes of galaxies [PDF]
We demonstrate that the feedback from stellar bulges can play an essential role in shaping the halo gas of galaxies with substantial bulge components by conducting 1-D hydrodynamical simulations.

Implementation of stellar heating feedback in simulations of star cluster formation: effects on the initial mass function [PDF]
Explaining the initial mass function (IMF) of stars is a long-standing problem in astrophysics. The number of complex mechanisms involved in the process of star cluster formation, such as turbulence, magnetic fields and stellar feedback, make understanding and modeling the IMF a challenging task.
