Feedback-driven anisotropy in the circumgalactic medium for quenching galaxies in the SIMBA simulations [PDF]
arXiv, 2023 We use the SIMBA galaxy formation simulation suite to explore anisotropies in the properties of circumgalactic gas that result from accretion and feedback processes. We particularly focus on the impact of bipolar active galactic nuclei (AGN) jet feedback as implemented in SIMBA, which quenches galaxies and has a dramatic effect on large-scale gas ...

The Role of Stellar Feedback in Galaxy Evolution
, 2009 Aiming at understanding the role of stellar feedback in galaxy evolution, I present a study of the hot interstellar medium in several representative galaxies, based primarily on X-ray observations as well as theoretical modelling. I find that, in the massive disk galaxies NGC2613 and M104, the observed amount of hot gas is much less than that ...

Pre-supernova stellar feedback in nearby starburst dwarf galaxies [PDF]
A&A, 685 (2024) A46Stellar feedback in dwarf galaxies remains, to date, poorly explored, yet is crucial to understanding galaxy evolution in the early Universe. In particular, pre-supernova feedback has recently been found to play a significant role in regulating and disrupting star formation in larger spiral galaxies, but it remains uncertain if it also plays this role ...

The stellar mass function and star formation rate-stellar mass relation of galaxies at z ~ 4 - 7
, 2015 We investigate the evolution of the star formation rate-stellar mass relation (SFR-M*) and Galaxy Stellar Mass Function (GSMF) of z ~ 4-7 galaxies, using cosmological simulations run with the smoothed particle hydrodynamics code P-GADGET3(XXL).

Supergiant Shells and Molecular Cloud Formation in the LMC
, 2012 We investigate the influence of large-scale stellar feedback on the formation of molecular clouds in the Large Magellanic Cloud (LMC). Examining the relationship between HI and 12CO(J=1-0) in supergiant shells (SGSs), we find that the molecular fraction ...

The Astrophysical JournalWe investigate the driving mechanisms for the H i gas content in star-forming central galaxies at low redshift, by examining the H i -to-stellar mass ratio ( M _H _i / M _* ) in both the state-of-the-art hydrodynamic simulations, IllustrisTNG (TNG) and ...

On the Effect of Magnetic Spots on Stellar Winds and Angular Momentum Loss
, 2009 We simulate the effect of latitudinal variations in the location of star spots, as well as their magnetic field strength, on stellar angular momentum loss to the stellar wind.
