Galaxy formation in the Planck cosmology – I. Matching the observed evolution of star formation rates, colours and stellar masses [PDF]

open access: yes, 2014
We have updated the Munich galaxy formation model to the Planck first-year cosmology, while modifying the treatment of baryonic processes to reproduce recent data on the abundance and passive fractions of galaxies from z = 3 down to z = 0. Matching these

Chemodynamical Modelling of Galaxy Formation and Evolution [PDF]

open access: yes, 2002
We present our recently developed 3-dimensional chemodynamical code for galaxy evolution. This code follows the evolution of different galactic components like stars, dark matter and different components of the interstellar medium (ISM), i.e. a diffuse gaseous phase and the molecular clouds.

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,

Numerical simulations of the chemical evolution of complex gravitating disk and dwarf galaxies system

open access: yesВісник Астрономічної школи, 2004
In this work we have simulated the evolution of disk and dwarf galaxies gravitating system, using our viscosity algorithm. We investigated changes in disk galaxy chemical abundance due to minor merger of dwarf galaxy with lower abundance of heavy ...

Evolution of dwarf galaxies in the Centaurus A group [PDF]

open access: yes, 2007
We consider star formation properties of dwarf galaxies in Cen A group observed within our HST/ACS projects number 9771 and 10235. We model color-magnitude diagrams of the galaxies under consideration and measure star formation rate and metallicity dependence on time.

Ages and metallicities of central and satellite galaxies: implications for galaxy formation and evolution [PDF]

open access: yes, 2009
Using the stellar ages and metallicities of galaxies in the Sloan Digital Sky Survey (SDSS) obtained by Gallazzi et al. and the SDSS galaxy group catalogue of Yang et al., we study how the stellar ages and metallicities of central and satellite galaxies ...

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.

Stochastic 2-D Models of Galaxy Disk Evolution. The Galaxy M33

open access: yesOpen Astronomy, 2014
We have developed a fast numerical 2-D model of galaxy disk evolution (resolved along the galaxy radius and azimuth) by adopting a scheme of parameterized stochastic self-propagating star formation.

The E-MOSAICS project: tracing galaxy formation and assembly with the age–metallicity distribution of globular clusters [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2019
We present 25 cosmological zoom-in simulations of Milky Way-mass galaxies in the `MOdelling Star cluster population Assembly In Cosmological Simulations within EAGLE' (E-MOSAICS) project.
