描述At close inspection every galaxy appears to have its own individuality.A galaxy can be warped, lop-sided, doubly-nucleated, boxy or disky, ... in its own specific, peculiar way. Hence, for a complete description, galaxy taxonomy may ask for finer and finer classification schemes. However, for some applications it may be more fruitful to let details aside and focus on some global properties of galaxies. One is then seeking to measure just a few quantities for each galaxy, a minimum set of globalobservables that yet captures some essential aspect of these objects. One very successful example of this approach is offered by the scaling rela­ tions of galaxies, the subject of the international workshop held at ESO head­ quarters in Garching on November 19-21, 1996. Discovered in the late 1970‘s, the Tully-Fisher relation for the spirals and the Faber-Jackson relation, or its more recent version the Fundamental Plane, for ellipticals have now become flourishing fields of astronomical research in their own right, as well as being widely used tools for a broad range of astronomical investigations. The work­ shop was designed to address three key issues on galaxy scaling relations, i.e., th

On Governance: Decision-Making in Families, . The ultraviolet Tully-Fisher relation of the HDF galaxies has a similar slope and zero-point to that of spiral galaxies nearby. These results should be taken with caution as there remain a number of potentially important systematic effects which remain to be calibrated.

The Role of Photoionization During Galaxy Formationating should have occurred in the past universe. Photoionization seems not to be adequate anyway. We briefly discussed an alternative possibility based on a warm IGM picture. In this picture photoionization may allow low mass galaxy formation which is inhibited otherwise.

The Physical Origin of the Fundamental Plane (of Elliptical Galaxies)le of orbital anisotropy and its relation with the FP thickness are also discussed. None of the explored solutions — albeit formally correct — are easily acceptable from a physical point of view, due to the ever-present problem of the required fine-tuning.

Unless halos of spiral galaxies formed at high redshift (. ≳ 1) and did not later accrete any significant amount of mass, the TullyFisher relation is not likely to be the direct result of cosmological initial conditions but rather a consequence of a subsequent feedback process.

Survival Tips for the Younger Cliniciannd the upcoming wide-field cameras, super-seeing imaging instruments, and the 8-m class telescopes will provide a great opportunity for the study of the mass distribution of isolated and cluster galaxies.

Christen D. Upper,Susan S. Hiranore formed early in elliptical galaxies, and give a reassuring confirmation of many previous contentions that the CM relation takes its origin at early times probably from galactic wind feedback. This conclusion is independent of the IMF, the SFR and the cosmological parameters.
