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 ...

The SMUGGLE-Ring project: Bar and bulge effects on nuclear disk and ring formation
Astronomy & AstrophysicsWe present the first results from the SMUGGLE-Ring project, a suite of simulations employing the Stars and MUltiphase Gas in GaLaxiEs (SMUGGLE) interstellar medium (ISM) and stellar feedback model to explore nuclear structures in Milky Way-mass galaxies.

Tracing the Origins of Hot Halo Gas in Milky Way–type Galaxies with SMUGGLE
The Astrophysical JournalCurrent galaxy formation models predict the existence of X-ray-emitting gaseous halos around Milky Way (MW)–type galaxies. To investigate properties of this coronal gas in MW-like galaxies, we analyze a suite of high-resolution simulations based on the ...

Stellar Population and Energy Feedback in the Supergiant Shell LMC 1
The Astronomical JournalSupergiant shells (SGSs) are the largest interstellar structures in galaxies and inject hot enriched gas into galactic halos. We have studied SGS LMC 1 to determine quantitatively whether stellar energy feedback is adequate to power the formation of an ...

Correlation between Baryonic Process and Galaxy Assembly Bias
The Astrophysical JournalGalaxy assembly bias (GAB) is the dependence of galaxy clustering on secondary properties beyond halo mass. In this work, we study the connections between GAB and baryonic processes using the Galacticus semianalytic model (SAM) for galaxy formation and ...

Stellar Feedback as Holographic Information Regulation
Application of Ontological Resolution Theory (ORT) to stellar astrophysics, demonstrating that stellar evolution is an active component of cosmological information regulation rather than merely a local thermodynamic process. Version 3 (November 2025) includes: • Rigorous effective horizon dynamics via screened Poisson equation on S² • Derivation of ...

Stellar Feedback and Chemical Evolution In Dwarf Galaxies
, 2019 Motivated by the desire to investigate two of the largest outstanding problems in galactic evolution -- stellar feedback and galactic chemical evolution -- we develop the first set of galaxy-scale simulations that simultaneously follow star formation with individual stars and their associated multi-channel stellar feedback and multi-element metal ...

Formation of the first galaxies under stellar feedback
, 2015 The stellar feedback is a crucial ingredient for modeling galaxy formation, especially for the first galaxies, which are susceptible to stellar feedback due to their shallow potential wells.
