In this paper we investigate whether Smoothed Particle Hydrodynamics (SPH), equipped with artificial conductivity, is able to capture the physics of density/energy discontinuities in the case of the so-called shearing layers test, a test for examinin

We present models of the formation and evolution of isolated dwarf galaxies. The models follow the evolution of an initially homogeneous gas cloud collapsing in a pre-existing dark-matter halo. These simplified initial conditions are supported by the

We investigate the global photometric scaling relations traced by early-type galaxies in different environments, ranging from dwarf spheroidals, over dwarf elliptical galaxies, up to giant ellipticals (−8 mag ≳ MV ≳ −24 mag). These results ar

dIrrs and flat, rotating dEs generally possess flat metallicity profiles while round dEs show strong metallicity gradients [8]. Unlike dEs, dIrrs also exhibit ongoing star formation (SF) [4], compatible with a continuous star formation history (SFH).

We show results based on a large suite of N-Body/SPH simulations of isolated, flat dwarf galaxies, both rotating and non-rotating. The main goal is to investigate possible mechanisms to explain the observed dichotomy in radial stellar metallicity pro

We have constructed a series of models to investigate the influence of tidal forces on the formation and evolution of dwarf spheroidal galaxies. These Nbody/SPH models consist of a model for an isolated dwarf spheroidal galaxy which is placed on an o

We present new fully self-consistent models of the formation and evolution of isolated dwarf galaxies. We have used the publicly available N-body/SPH code HYDRA, to which we have added a set of star formation criteria, and prescriptions for chemical
