Wide Field H - R diagrams of Local Group Dwarf Galaxies

We present new observations of Sextans and Leo I dwarf galaxies, that provide new insight on their stellar populations. The large sample of stars measured in Sextans allowed us to obtain a reliable estimate of the metal content of this galaxy, to study the population spatial gradients, and to investigate the nature of the large number of blue stragglers. In Leo I, we discovered a significant po...

Dwarf Galaxies of the Local Group

XMM-Newton and Chandra have ushered in a new era for the study of dwarf galaxies in the Local Group. We provide an overview of the opportunities, challenges, and some early results. The large number of background sources relative to galaxy sources is a major theme. Despite this challenge, the identification of counterparts has been possible, providing hints that the same mechanisms producing X-...

Chemo-dynamical Evolution of the ISM in Galaxies

Chemo-dynamical models have been introduced in the late eighties and are a generally accepted tool for understanding galaxy evolution. They have been successfully applied to one-dimensional problems, e.g. the evolution of nonrotating galaxies, and two-dimensional problems, e.g. the evolution of disk galaxies. Recently, also three-dimensional chemo-dynamical models have become available. In thes...

CHEMO – DYNAMICAL EVOLUTION OF DISK GALAXIES, SMOOTHED PARTICLES HYDRODYNAMICS APPROACH 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 into the 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 standard SPH model. Using this model we try to describe ...

Light - weight Local Group Dwarf Spheroidal Galaxies

A simple and natural explanation for the dynamics and morphology of the Local Group Dwarf Spheroidal galaxies, Draco (Dra) and Ursa Minor (UMi), is that they are weakly unbound stellar systems with no significant dark matter component. A gentle, but persistent, Milky Way (MW) tide has left them in their current kinematic and morphological state. This short paper reviews the parametric tidal int...
