The formation of disc galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 1998 We investigate the influence of the cooling epoch on the formation of galaxies in a cold dark matter dominated universe. Isolated haloes, with circular speeds typical of spiral galaxies, have been selected from a low resolution numerical simulation for re-simulation at higher resolution with dark matter and gas components.

The epoch of galaxy formation [PDF]
Proceedings of the National Academy of Sciences, 1997 Recent advances in technology have enabled astronomers to observe fainter, and more distant, galaxies and to study the processes of galaxy formation and evolution. Recent observations suggest that the bulk of the stars in the universe formed between z = 3 (∼1 × 10^9 years after the big bang) and the present.

Hierarchical galaxy formation [PDF]
Monthly Notices of the Royal Astronomical Society, 2002 We describe the GALFORM semi-analytic model for calculating the formation and evolution of galaxies in hierarchical models. It improves upon, and extends, the Cole et al 1994 model. The model employs a new Monte-Carlo algorithm to follow the merging evolution of dark matter halos with arbitrary mass resolution. It incorporates realistic descriptions of

Formation of Galaxy Clusters [PDF]
Annual Review of Astronomy and Astrophysics, 2012 Formation of galaxy clusters corresponds to the collapse of the largest gravitationally bound overdensities in the initial density field and is accompanied by the most energetic phenomena since the Big Bang and by the complex interplay between gravity-induced dynamics of collapse and baryonic processes associated with galaxy formation. Galaxy clusters

EMERGE – an empirical model for the formation of galaxies since z ∼ 10 [PDF]
, 2017 We present EMERGE, an Empirical ModEl for the foRmation of GalaxiEs, describing the evolution of individual galaxies in large volumes from z similar to 10 to the present day.

Stellar masses and star formation histories for 105 galaxies from the Sloan Digital Sky Survey [PDF]
, 2002 We develop a new method to constrain the star formation histories, dust attenuation and stellar masses of galaxies. It is based on two stellar absorption-line indices, the 4000-A break strength and the Balmer absorption-line index Hδ A .

Symposium - International Astronomical Union, 1987 Theories of galaxy formation via hierarchical clustering of cold dark matter and by fragmentation of gaseous pancakes or shells are reviewed and compared. Dissipative processes are crucial to all theories of galaxy formation, and are discussed in terms of a simple model involving multiple cloud interactions.

Proceedings of the National Academy of Sciences, 1998 It is argued that within the standard Big Bang cosmological model the bulk of the mass of the luminous parts of the large galaxies likely had been assembled by redshift z ∼ 10. Galaxy assembly this early would be difficult to fit in the widely discussed adiabatic cold dark matter model for structure formation ...

The Auriga Project: the properties and formation mechanisms of disc galaxies across cosmic time [PDF]
, 2016 We introduce a suite of 30 cosmological magneto-hydrodynamical zoom simulations of the formation of galaxies in isolated Milky Way mass dark haloes. These were carried out with the moving mesh code arepo, together with a comprehensive model for galaxy ...
