Galaxy formation and evolution

open access: yesTheoretical and Natural Science, 2023
Galaxies as the most important structures in the universe and Galaxy formation is a sequential redistribution process.The basic picture of galaxy formation was first proposed by White and Rees.The physical processes involved in galaxy formation are very numerous and complex. We know very little about most of these processes.

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 ...

Dust-regulated galaxy formation and evolution: a new chemodynamical model with live dust particles [PDF]

open access: yes, 2015
Interstellar dust plays decisive roles in the conversion of neutral to molecular hydrogen (H_2), the thermodynamical evolution of interstellar medium (ISM), and the modification of spectral energy distributions (SEDs) of galaxies.

Galaxy Evolution with Manifold Learning [PDF]

open access: yesEntropy
Matter in the early Universe was nearly uniform, and galaxies emerged through the gravitational growth of small primordial density fluctuations. Astrophysics has been trying to unveil the complex physical phenomena that have caused the formation and ...

Galaxy formation and evolution: low-surface-brightness galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1998
We investigate in detail the hypothesis that low surface brightness galaxies (LSB) differ from 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 infall dependence on surface density as used in models of the Milky Way.

Understanding Galaxy Formation and Evolution [PDF]

open access: yes, 2007
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 Matter (LCDM) model. This scenario emerged mainly to explain the origin of galaxies.

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

open access: yesOpen 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
