Pre-supernova feedback sets the star cluster mass function to a power law and reduces the cluster formation efficiency [PDF]
A&A 681, A28 (2024), 2023 The star cluster initial mass function is observed to have an inverse power law exponent around 2, yet there is no consensus on what determines this distribution, and why some variation is observed in different galaxies. Furthermore, the cluster formation efficiency covers a range of values, particularly when considering different environments.

Feedback first: the surprisingly weak effects of magnetic fields, viscosity, conduction, and metal diffusion on galaxy formation [PDF]
, 2017 Using high-resolution simulations with explicit treatment of stellar feedback physics based on the FIRE (Feedback in Realistic Environments) project, we study how galaxy formation and the interstellar medium (ISM) are affected by magnetic fields ...

The Kinematic Bimodality: Efficient Feedback and Cold Gas Deficiency in Slow-rotating Galaxies
The Astrophysical Journal Letters, 2023 The bimodality in the stellar spin of low-redshift (massive) galaxies, ubiquitously existing at all star formation levels and in diverse environments, suggests that galaxies grow and quench through two diverged evolutionary pathways.

Stellar evolution and feedback connections to stellar dynamics [PDF]
Proceedings of the International Astronomical Union, 2006 AbstractUntil a few years ago, the common paradigm for the formation of Globular Clusters (GCs) was that they constitute a ‘simple stellar population’ in which all the stars were formed from a chemically homogeneous cluster medium within a relatively short interval of time, at the beginning of the galactic life.

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 ...

The Structure of the Interstellar Medium of Star Forming Galaxies [PDF]
, 2012 We present numerical methods for including stellar feedback in galaxy-scale simulations. We include heating by SNe (I & II), gas recycling and shock-heating from O-star & AGB winds, HII photoionization, and radiation pressure from stellar photons.

Stellar dynamics and feedback connections to stellar evolution [PDF]
Proceedings of the International Astronomical Union, 2006 AbstractIn dense stellar systems, dynamical interactions between objects inevitably lead to frequent formation of exotic stellar objects and multiple systems, thereby imposing new questions for the stellar evolution theory. The evolutionary path of such systems could be different from that of the unperturbed objects, therefore, we must re-evaluate ...

Stellar feedback and triggered star formation [PDF]
Proceedings of the International Astronomical Union, 2009 AbstractYoung, massive stars influence their ambient medium through winds and radiation. The outcome of this feedback depends on the number of massive stars in a star cluster and on the density of the ambient medium. This contribution is based on a comparison of observations to the results of numerical simulations.

Low-mass galaxy assembly in simulations: regulation of early star formation by radiation from massive stars [PDF]
, 2014 Despite recent success in forming realistic present-day galaxies, simulations still form the bulk of their stars earlier than observations indicate. We investigate the process of stellar mass assembly in low-mass field galaxies, a dwarf and a typical ...
