Globular cluster formation in the context of galaxy formation and evolution [PDF]

, 2014
The formation of globular clusters (GCs) remains one of the main unsolved problems in star and galaxy formation. The past decades have seen important progress in constraining the physics of GC formation from a variety of directions.

Cosmological evolution and hierarchical galaxy formation [PDF]

Monthly Notices of the Royal Astronomical Society, 1999
We provide a new multi-waveband compilation of the data describing the cosmological evolution of quasars, and discuss a model that attributes the evolution to variation in the rate of merging between dark halos in a hierarchical universe. We present a new Press-Schechter calculation of the expected merger rate and show that this can reproduce the ...

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 ...

The evolution of galaxy formation [PDF]

Astronomy & Geophysics, 2011
Our history of understanding galaxy formation could be traced through the development of individual ideas. A cynic might be tempted to suggest that new catchphrases are developed at a faster rate than genuine progress is made.

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 ...

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 ...

Chemodynamical Modelling of Galaxy Formation and Evolution [PDF]

Astrophysics and Space Science, 2002
We present our recently developed 3-dimensional chemodynamical code for galaxy evolution. This code follows the evolution of different galactic components like stars, dark matter and different components of the interstellar medium (ISM), i.e. a diffuse gaseous phase and the molecular clouds.

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 ...

Galaxy Formation Theory [PDF]

, 2010
We review the current theory of how galaxies form within the cosmological framework provided by the cold dark matter paradigm for structure formation. Beginning with the pre-galactic evolution of baryonic material we describe the analytical and numerical

The Morphology of the Active Galactic Nucleus and its Impact on Accretion Flows and Relativistic Jets

Physical Sciences Forum, 2023
The G2 gas cloud motion data and the scarcity of observations on the event horizon-scale distances have challenged the comprehensiveness of the central supermassive black hole model.
