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 ...

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 ...

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.

Chemical Evolution of Galaxies [PDF]

open access: yes, 2000
Chemical evolution of galaxies brings together ideas on stellar evolution and nucleosynthesis with theories of galaxy formation, star formation and galaxy evolution, with all their associated uncertainties.

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.

The GALEX Extended Mission: Surveying UV Tracers of the Hidden Side of Galaxy Evolution [PDF]

open access: yes, 2010
The Galaxy Evolution Explorer (GALEX) continues its surveys of the ultraviolet sky. GALEX surveys have supported the following galaxy evolution investigations: calibrating UV as a star formation rate tracer, using wide and deep surveys to measure star ...

Galaxy Formation Theory [PDF]

open access: yes, 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

Parallelization, Special Hardware and Post-Newtonian Dynamics in Direct N - Body Simulations [PDF]

open access: yes, 2008
The formation and evolution of supermassive black hole (SMBH) binaries during and after galaxy mergers is an important ingredient for our understanding of galaxy formation and evolution in a cosmological context, e.g.

Galaxy formation with radiative and chemical feedback [PDF]

open access: yes, 2015
Here we introduce GAMESH, a novel pipeline which implements self-consistent radiative and chemical feedback in a computational model of galaxy formation. By combining the cosmological chemical-evolution model GAMETE with the radiative transfer code CRASH,

Internal Secular Evolution in Disk Galaxies: The Growth of Pseudobulges

open access: yes, 2007
Observational and theoretical evidence that internal, slow ("secular") evolution reshapes galaxy disks is reviewed in Kormendy & Kennicutt (2004, ARAA, 42, 603). This update has three aims.
