Formation of Galaxy Clusters [PDF]

open access: yesAnnual Review of Astronomy and Astrophysics, 2012
In this review, we describe our current understanding of cluster formation: from the general picture of collapse from initial density fluctuations in an expanding Universe to detailed simulations of cluster formation including the effects of galaxy ...

DLAs and Galaxy Formation [PDF]

open access: yesModern Physics Letters A, 2007
Damped Lyman-alpha systems (DLAs) are useful probes of star formation and galaxy formation at high redshift. We study the physical properties of DLAs and their relationship to Lyman-break galaxies using cosmological hydrodynamic simulations based on the ...

Galaxy Formation Theory [PDF]

open access: yesPhysics Reports, 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

Feedback in Galaxy Formation [PDF]

open access: yesProceedings of the International Astronomical Union, 2011
I review the outstanding problems in galaxy formation theory, and the role of feedback in resolving them. I address the efficiency of star formation, the galactic star formation rate, and the roles of supernovae and supermassive black holes.Comment: To ...

Quasars and galaxy formation [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1999
Quasars are widely believed to be powered by accretion onto supermassive black holes and there is now considerable evidence for a link between mergers, quasars and the formation of spheroids. Cattaneo, Haehnelt & Rees (1999) have demonstrated that a very

Galaxy formation [PDF]

open access: yesProceedings 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 Science of Galaxy Formation [PDF]

open access: yesProceedings of the International Astronomical Union, 2008
Our knowledge of the Universe remains discovery-led: in the absence of adequate physics-based theory, interpretation of new results requires a scientific methodology.

Hierarchical galaxy formation [PDF]

open access: yesMonthly 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

The Formation of Galaxy Disks

open access: yes, 2008
We present a new set of multi-million particle SPH simulations of the formation of disk dominated galaxies in a cosmological context. Some of these galaxies are higher resolution versions of the models already described in Governato et al (2007).
