The star-formation history of the Milky Way Galaxy

, 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 ...

The Role of Dust in the Early Universe I : Protogalaxy Evolution [PDF]

, 2011
We develop one-zone galaxy formation models in the early Universe, taking into account dust formation and evolution by supernova (SN) explosions. Especially we focus on the time evolution of dust size distribution, because ${\rm H}_{2}$ formation on the ...

Simulations of galaxy formation and evolution [PDF]

Astronomische Nachrichten, 2012
AbstractWe discuss recent results of hydrodynamical simulations of galaxy formation in a Λ Cold Dark Matter universe, focusing on galaxies of similar mass to the Milky Way, and with a variety of formation and merger histories. We investigate the present‐day properties of disks and spheroids, in terms of stellar ages, spatial structure and dynamics; as ...

Luminosity function of binary X-ray sources calculated using the Scenario Machine

, 2007
Using the ``Scenario Machine'' we have carried out a population synthesis of X-ray binaries for the purpose of modelling of X-ray luminosity functions (XLFs) in different types of galaxies: star burst, spiral, and elliptical. This computer code allows to

On the Determination of Star Formation Rates in Evolving Galaxy Populations [PDF]

, 2000
The redshift dependence of the luminosity density in certain wavebands (e.g. UV and H-alpha) can be used to infer the history of star formation in the populations of galaxies producing this luminosity.

What Regulates Galaxy Evolution? Open Questions in Our Understanding of Galaxy Formation and Evolution

, 2014
In April 2013, a workshop entitled "What Regulates Galaxy Evolution" was held at the Lorentz Center. The aim of the workshop was to bring together the observational and theoretical community working on galaxy evolution, and to discuss in depth of the ...
