Insights on the Sun Birth Environment in the Context of Star Cluster Formation in Hub–Filament Systems

The Astrophysical Journal Letters, 2023
Cylindrical molecular filaments are observed to be the main sites of Sunlike star formation, while massive stars form in dense hubs at the junction of multiple filaments.

Star formation in high redshift galaxies including Supernova feedback: effect on stellar mass and luminosity functions [PDF]

, 2014
We present a semi-analytical model of high redshift galaxy formation. In our model the star formation inside a galaxy is regulated by the feedback from supernova (SNe) driven outflows. We derive a closed analytical form for star formation rate in a single galaxy taking account of the SNe feedback in a self-consistent manner.

Nature versus nurture: what regulates star formation in satellite galaxies? [PDF]

, 2018
We use our state-of-the-art Galaxy Evolution and Assembly (GAEA) semi-analytic model to study how and on which time-scales star formation is suppressed in satellite galaxies.

Bursting with Feedback: The Relationship between Feedback Model and Bursty Star Formation Histories in Dwarf Galaxies

The Astrophysical Journal
Due to their inability to self-regulate, ultrafaint dwarfs are sensitive to prescriptions in subgrid physics models that converge and regulate at higher masses.

2a Results: galaxy to cloud scales

Frontiers in Astronomy and Space Sciences, 2023
Simulations from the scales of isolated galaxies to clouds have been instrumental in informing us about molecular cloud formation and evolution. Simulations are able to investigate the roles of gravity, feedback, turbulence, heating and cooling, and ...

Stellar hydrodynamical modeling of dwarf galaxies: simulation methodology, tests, and first results

, 2015
Cosmological simulations still lack numerical resolution or physical processes to simulate dwarf galaxies in sufficient details. Accurate numerical simulations of individual dwarf galaxies are thus still in demand.

Mass Distribution in Galaxy Clusters: the Role of AGN Feedback [PDF]

, 2010
We use 1 kpc resolution cosmological AMR simulations of a Virgo-like galaxy cluster to investigate the effect of feedback from supermassive black holes (SMBH) on the mass distribution of dark matter, gas and stars. We compared three different models: (i)

The Origin of the Nuclear Star-forming Ring in NGC 3182

The Astronomical Journal, 2023
We investigate the stellar and ionized gas kinematics, and stellar populations of NGC 3182 galaxy using integral field spectrograph data from the Calar Alto Legacy Integral Field Area survey. We try to clarify the nature of the ring structure in NGC 3182.

Disruption of giant molecular clouds and formation of bound star clusters under the influence of momentum stellar feedback

, 2019
Energetic feedback from star clusters plays a pivotal role in shaping the dynamical evolution of giant molecular clouds (GMCs). To study the effects of stellar feedback on the star formation efficiency of the clouds and the dynamical response of embedded

Radiative stellar feedback in galaxy formation: Methods and physics [PDF]

Monthly Notices of the Royal Astronomical Society, 2019
ABSTRACT Radiative feedback (RFB) from stars plays a key role in galaxies, but remains poorly understood. We explore this using high-resolution, multifrequency radiation-hydrodynamics (RHD) simulations from the Feedback In Realistic Environments (FIRE) project.
