GAIA: Composition, Formation and Evolution of the Galaxy [PDF]

open access: bronzeAstronomy & Astrophysics, 2001
The GAIA astrometric mission has recently been approved as one of the next two `cornerstones' of ESA's science programme, with a launch date target of not later than mid-2012.

Galaxy Formation and Evolution [PDF]

open access: green, 2005
We take a multi-faceted approach to study galaxy populations in the local universe, using the completed Two Degree Field Galaxy Redshift Survey (2dFGRS), the ``Millennium Run'' LCDM N-body simulation, and a semi-analytic model of galaxy formation.

Formation and evolution of disk galaxies [PDF]

open access: yesProceedings of the International Astronomical Union, 2008
Global 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 Tully ...

The formation and evolution of massive galaxies [PDF]

open access: yesResearch in Astronomy and Astrophysics, 2021
The discovery of massive galaxies at high redshifts, especially the passive ones, poses a big challenge for the current standard galaxy formation models. Here we use the semi-analytic galaxy formation model developed by Henriques et al.

Formation and Evolution of Galaxies [PDF]

open access: bronzeTransactions of the International Astronomical Union, 1988
At the beginning of this review period a number of arguments were put forward against the neutrino model which became popular in 1980-1983: too high a rate of the structure evolution at the non-linear stage and the same difficulty in the galaxy formation.

Cosmological evolution and hierarchical galaxy formation [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1998
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.

Understanding Galaxy Formation and Evolution [PDF]

open access: yes, 2006
The old dream of integrating into one the study of micro and macrocosmos is now a reality. Cosmology, astrophysics, and particle physics intersect in a scenario (but still not a theory) of cosmic structure formation and evolution called Lambda Cold Dark ...

Disk Galaxy Models Driven by Stochastic Self-Propagating Star Formation

open access: yesOpen Astronomy, 2010
We present a model of chemical and spectrophotometric evolution of disk galaxies based on a stochastic self-propagating star formation scenario. The model incorporates galaxy formation through the process of accretion, chemical and photometric evolution ...

The star-formation history of the Milky Way Galaxy [PDF]

open access: yesProceedings of IAU Symposium 258, (2009), 'The Ages of Stars', eds Mamajek, Soderblom & Wyse p. 11-22, 2009
The star-formation histories of the main stellar components of the Milky Way constrain critical aspects of galaxy formation and evolution. I discuss recent determinations of such histories, together with their interpretation in terms of theories of disk galaxy evolution.

Galaxy peculiar velocities and evolution-bias [PDF]

open access: yes, 2007
Galaxy bias can be split into two components: a formation-bias based on the locations of galaxy creation, and an evolution-bias that details their subsequent evolution. In this letter we consider evolution-bias in the peaks model. In this model, galaxy formation takes place at local maxima in the density field, and we analyse the subsequent peculiar ...
