  journal={Astrophysics and Space Science},
We present a 3d code for the dynamical evolution of a multi-phase interstellar medium (ISM) coupled to stars via star formation (SF) and feedback processes. The multi-phase ISM consists of clouds (sticky particles) and diffuse gas (SPH): exchange of matter, energy and momentum is achieved by drag (due to ram pressure) and condensation or evaporation processes. The cycle of matter is completed by SF and feedback by SNe and PNe. A SF scheme based on a variable SF efficiency as proposed by… 

Massive elliptical galaxies in X-rays: The role of late gas accretion

We present a new chemical evolution model meant to be a first step in the self-consistent study of both optical and X-ray properties of elliptical galaxies. Detailed cooling and heating processes in

Evolution of dwarf-elliptical galaxies

Here we present as an extension to already published models of massive spherical galaxies one-dimensional chemo-dynamical models of dwarf elliptical galaxies in the mass range between 10 9 and 10 10

Physical Processes in Star–Gas Systems

Abstract We first present a recently developed three-dimensional chemodynamic code for galaxy evolution from the Kiev–Kiel collaboration. It follows the evolution of all components of a galaxy, such



Modeling the Evolution of Disk Galaxies. I. The Chemodynamical Method and the Galaxy Model

Here we present our two-dimensional chemodynamical code CoDEx, which we developed for the purpose of modeling the evolution of galaxies in a self-consistent manner. The code solves the hydrodynamical

Supernova remnant revolution in an inhomogeneous medium. I - Numerical models

The first numerical simulations of supernova remnant evolution in an inhomogeneous gas are presented. Evolution in the lowest density substrate (the intercloud) is assumed to be spherically symmetric

Nearly self-consistent disc–bulge–halo models for galaxies

We describe methods for setting up self-consistent disc-bulge-halo galaxy models. The bulge and halo distribution functions (DFs) are functions of E and L(z) only. The halo's flattening and rotation

A Universal Formation Mechanism for Open and Globular Clusters in Turbulent Gas

A universal mechanism for cluster formation in all epochs and environments is found to be consistent with the properties and locations of young and old globular clusters, open clusters and unbound

The distribution of low-mass stars in the Galactic disc

We quantify the complex interdependence of stellar binarity, the stellar mass-luminosity relation, the mass function, the colour-magnitude relation and Galactic disc structure, all of which must be

TREESPH: A Unification of SPH with the Hierarchical Tree Method

A new, general-purpose code for evolving three-dimensional, self-gravitating fluids in astrophyics, both with and without collisionless matter, is described. In this TREESPH code, hydrodynamic
