Galaxy formation and evolution - I. The Padua TREE-SPH code (PD-SPH)

MODELING THE STAR FORMATION IN GALAXIES USING THE CHEMO - DYNAMICAL SPH CODE Chemo - dynamical SPH code

A new Chemo Dynamical Smoothed Particle Hydrodynamic (CD SPH) code is presented. The disk galaxy is described as a multi fragmented gas and star system, embedded in a cold dark matter halo. The star formation (SF) process, SNII, SNIa and PN events as well as chemical enrichment of gas have been considered within the framework of the standard SPH model. Using this model we describe the dynamical...

A&a Manuscript No. an Sph Code for Galaxy Formation Problems Presentation of the Code

We present and test a code for two-uid simulations of galaxy formation, one of the uids being collision-less. The hydrodynamical evolution is solved through the SPH method while gravitational forces are calculated using a tree method. The code is Lagrangian, and fully adaptive both in space and time. A signiicant fraction gas in simulations of hierarchical galaxy formation ends up in tight clum...

A Multi-phase Chemo-dynamical Sph Code for Galaxy Evolution. Testing the Code

In this paper we present some test results of our newly developed Multi-Phase Chemo-Dynamical Smoothed Particle Hydrodynamics (MP-CD-SPH) code for galaxy evolution. At first, we present a test of the “pure” hydro SPH part of the code. Then we describe and test the multi-phase description of the gaseous components of the interstellar matter. In this second part we also compare our condensation a...

Analyze of the star formation modeling algorithm in SPH code

Abstract. The chemical and photometric evolution of star forming disk galaxies is investigated. Numerical simulations of the complex gasdynamical flows are based on our own coding of the Chemo Dynamical Smoothed Particle Hydrodynamical (CD SPH) approach, which incorporates the effects of star formation. As a first application, the model is used to describe the chemical and photometric evolution...
