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.

M-σ relations across cosmic time
The Open Journal of Astrophysics, 2023 Feedback from active galactic nuclei (AGN) has long been invoked to explain the correlation between black hole mass and stellar velocity dispersion (M-σ) discovered in low redshift galaxies. We describe the time evolution of AGN in the M-σ plane based on

Cosmic Feedback from AGN [PDF]
, 2009 Accretion onto the massive black hole at the centre of a galaxy can feed energy and momentum into its surroundings via radiation, winds and jets. Feedback due to radiation pressure can lock the mass of the black hole onto the M-sigma relation, and shape ...

Numerical Simulations of High Redshift Star Formation in Dwarf Galaxies [PDF]
, 2002 We present first results from three-dimensional hydrodynamic simulations of the high redshift formation of dwarf galaxies. The simulations use an Eulerian adaptive mesh refinement technique to follow the non-equilibrium chemistry of hydrogen and helium ...

Black holes on FIRE: stellar feedback limits early feeding of galactic nuclei [PDF]
, 2017 We introduce massive black holes (BHs) in the Feedback In Realistic Environments (FIRE) project and perform high-resolution cosmological hydrodynamic simulations of quasar-mass haloes [Mhalo(z = 2) ≈ 1012.5 M⊙] down to z = 1.

The impact of stellar feedback from velocity-dependent ionized gas maps – a MUSE view of Haro 11 [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We have used the capability of the Multi-Unit Spectroscopic Explorer (MUSE) instrument to explore the impact of stellar feedback at large scales in Haro 11, a galaxy under extreme starburst conditi ...

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.

The degeneracy between star-formation parameters in dwarf galaxy simulations and the Mstar-Mhalo relation [PDF]
, 2012 We present results based on a set of N-Body/SPH simulations of isolated dwarf galaxies. The simulations take into account star formation, stellar feedback, radiative cooling and metal enrichment.
