Galaxy formation with radiative and chemical feedback [PDF]

, 2015
Here we introduce GAMESH, a novel pipeline which implements self-consistent radiative and chemical feedback in a computational model of galaxy formation. By combining the cosmological chemical-evolution model GAMETE with the radiative transfer code CRASH,

Analysis of the Functions of Cosmology Dust in Galaxy Formation

Theoretical and Natural Science, 2023
The physical laws related to star formation in galaxies are the key to understanding the formation and evolution of galaxies. The dust in the interstellar medium has a significant effect on both the star formation and the observational properties of the ...

Astraeus I: the interplay between galaxy formation and reionization [PDF]

, 2020
We introduce a new self-consistent model of galaxy evolution and reionization, ASTRAEUS (semi-numerical rAdiative tranSfer coupling of galaxy formaTion and Reionization in N-body dArk mattEr simUlationS), which couples a state-of-the-art N-body ...

Formation and Evolution of Disk Galaxies [PDF]

Proceedings of the International Astronomical Union, 2003
AbstractGlobal star formation is the key to understanding galaxy disk formation. This in turn depends on gravitational instability of disks and continuing gas accretion as well as minor merging. A key component is feedback from supernovae. Primary observational constraints on disk galaxy formation and evolution include the Schmidt-Kennicutt law, the ...

The GALEX Extended Mission: Surveying UV Tracers of the Hidden Side of Galaxy Evolution [PDF]

, 2010
The Galaxy Evolution Explorer (GALEX) continues its surveys of the ultraviolet sky. GALEX surveys have supported the following galaxy evolution investigations: calibrating UV as a star formation rate tracer, using wide and deep surveys to measure star ...

UGC 7639: A Dwarf Galaxy in the Canes Venatici I Cloud

Advances in Astronomy, 2015
We want to get insight into the formation mechanism and the evolution of UGC 7639, a dwarf galaxy in the Canes Venatici I Cloud (CVnIC). We used archival multiwavelength data to constrain its global properties. Ultraviolet images show that UGC 7639 inner

The impact of radial migration on disk galaxy star formation histories

Astronomy & Astrophysics
Knowledge of the spatially resolved star formation history (SFH) of disk galaxies provides crucial insight into disk assembly, quenching, and chemical evolution.

Scaling Properties of Galaxy Groups

Universe, 2021
Galaxy groups and poor clusters are more common than rich clusters, and host the largest fraction of matter content in the Universe. Hence, their studies are key to understand the gravitational and thermal evolution of the bulk of the cosmic matter ...

The Gaia-ESO survey: Open clusters as tracers of galactic chemical evolution

Astronomy & Astrophysics
Aims. We investigate the formation and evolutionary trajectory of the Milky Way’s inner and outer galactic regions using stars from open clusters in the Gaia-ESO OC survey. Methods. Using numerical simulations from Chempy, we leveraged Markov chain Monte
