Synopsis Stellar Disk Evolution and Gaseous Disk Turbulence of Dwarf Irregular Galaxies by : Hong-Xin Zhang

This book focuses on the stellar disk evolution and gas disk turbulence of the most numerous galaxies in the local Universe – the dwarf galaxies. The “outside-in” disk shrinking mode was established for a relatively large sample of dwarf galaxies for the first time, and this is in contrast to the “inside-out” disk growth mode found for spiral galaxies. Double exponential brightness profiles also correspond to double exponential stellar mass profiles for dwarf galaxies, which is again different from most spiral galaxies. The cool gas distribution in dwarf galaxies was probed with the spatial power spectra of hydrogen iodide (HI) gas emission, and provided indirect evidence that inner disks of dwarf galaxies have proportionally more cool gas than outer disks. The finding that no correlation exists between gas power spectral indices and star formation gave important constraints on the relation between turbulence and star formation in dwarf galaxies.

Synopsis The Evolution of Galaxies by : Marc Sauvage

Galaxies have a history. This has become clear from recent sky surveys which have shown that distant galaxies, formed early in the life of the Universe, differ from the nearby ones. New observational windows at ultraviolet, infrared and millimetric wavelengths (provided by ROSAT, IRAM, IUE, IRAS, ISO) have revealed that galaxies contain a wealth of components: very hot gas, atomic hydrogen, molecules, dust, dark matter ... A significant advance is expected due to new instruments (VLT, FIRST, XMM) which will allow one to explore the most distant Universe. Three Euroconferences have been planned to punctuate this new epoch in galactic research, bringing together specialists in various fields of Astronomy.

Synopsis Dwarf Galaxies: Keys to Galaxy Formation and Evolution by : Polychronis Papaderos

Dwarf galaxy research constitutes an extremely vibrant field of astrophysical research, with many long-standing questions still unsettled and new ones constantly arising. The intriguing diversity of the dwarf galaxy population, observed with advanced ground-based and space-borne observatories over a wide spectral window providing an unprecedented level of detail, poses new challenges for both observers and theoreticians. The aim of this symposium was to bring together these two groups to exchange ideas and new results on the many evolutionary aspects of and open issues concerning dwarf galaxies. The main topics addressed include: the birth of dwarf galaxies: theoretical concepts and observable relics across wavelengths and time, the morphological, structural and chemical evolution of dwarf galaxies, possible evolutionary connections between early-type and late-type dwarfs, the star formation history of dwarf galaxies and its dependence on intrinsic and environmental properties, the origin and implications of starburst activity in dwarf galaxies, the fate of dwarfish systems born out of tidally ejected matter in galaxy collisions.

Synopsis The Legacy of J.C. Kapteyn by : Jacobus Cornelius Kapteyn

Jacobus Cornelius Kapteyn (1851-1922) of the University of Groningen was one of the foremost astronomers of his time, resulting in a leading role internationally of Dutch astronomy throughout the twentieth century. This volume, which is the proceedings of a special `legacy' symposium at the celebration of the 385th anniversary of the University of Groningen, addresses Kapteyn's influence on the development of modern astronomy through studies of his pioneering work on statistical astronomy and the Structure of the Sidereal System, and his leadership in establishing international collaborations, in particular the Plan of Selected Areas. In addition to historical studies related to Kapteyn's person, work, international collaborations and organisational efforts, the volume discusses the influence of Kapteyn on the internationalisation of astronomy and on contemporary astronomy. It also provides an inventory of Kapteyn's correspondence.
