GAIA: Composition, formation and evolution of the Galaxy [PDF]

Astronomy & Astrophysics, 2001
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]

Research 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.

Disk Galaxy Models Driven by Stochastic Self-Propagating Star Formation

Open 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 ...

Models of Late-type Disk Galaxies: 1-D Versus 2-D

Open Astronomy, 2014
We investigate the effects of stochasticity on the observed galaxy parameters by comparing our stochastic star formation two-dimensional (2-D) galaxy evolution models with the commonly used one-dimensional (1-D) models with smooth star formation. The 2-D

Monolithic View of Galaxy Formation and Evolution [PDF]

Galaxies, 2014
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 ...

Understanding Galaxy Formation and Evolution [PDF]

, 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 ...

Galaxy Formation and Evolution: Low Surface Brightness Galaxies [PDF]

Monthly Notices of the Royal Astronomical Society, 1998
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]

Monthly Notices of the Royal Astronomical Society, 2019
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).

Formation and Evolution of Galaxies [PDF]

Transactions 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.

The Formation and Evolution of Galaxies

, 1998
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.
