GAIA: Composition, formation and evolution of the Galaxy [PDF]
The GAIA astrometric mission has recently been approved as one of thenext two ``cornerstones'' of ESA's science programme, with a launch datetarget of not later than mid-2012.

The formation and evolution of massive galaxies [PDF]
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]
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.

Monolithic View of Galaxy Formation and Evolution [PDF]
We review and critically discuss the current understanding of galaxy formation and evolution limited to Early Type Galaxies (ETGs) as inferred from the observational data and briefly contrast the hierarchical and quasi-monolithic paradigms of formation ...

The Formation and Evolution of Galaxies
Galaxies represent the visible fabric of the Universe and there has been considerable progress recently in both observational and theoretical studies. The underlying goal is to understand the present-day diversity of galaxy forms, masses and luminosities.

Galaxy Formation and Evolution: Low Surface Brightness Galaxies [PDF]
We investigatein detail the hypothesisthat low surfacebrightnessgalaxies(LSB) differfrom ordinary galaxies simply because they form in halos with large spin parameters.We compute star formation rates using the Schmidt law, assuming the same gas ...

The formation and evolution of low-surface-brightness galaxies [PDF]
Our statistical understanding of galaxy evolution is fundamentally driven by objects that lie above the surface-brightness limits of current wide-area surveys (μ ∼ 23 mag arcsec−2).

The role of black holes in galaxy formation and evolution [PDF]
Virtually all massive galaxies, including our own, host central black holes ranging in mass from millions to billions of solar masses. The growth of these black holes releases vast amounts of energy that powers quasars and other weaker active galactic ...

The Formation and Evolution of Star Clusters and Galaxies [PDF]
AbstractThis paper addresses the questions of what we have learned about how and when dense star clusters form, and what studies of star clusters have revealed about galaxy formation and evolution. One important observation is that globular clusters are observed to form in galaxy mergers and starbursts in the local universe, which both provides ...
