9 The Goldstone Theorem
The mechanism of SSB does not only provide a general strategy for unifying the description of apparently different systems, but it also provide...

Orbit Dynamics, Stability and Chaos in Planetary Systems
Let us start with a problem of dynamical biology, which was posed about 800 years ago by Fibonacci1
-
Introduction to Part II
These notes arose from courses given at the International School for Advanced Studies (Trieste) and at the Scuola Normale Superiore (Pisa) in various...

6 Sectors with Energy-Momentum Density
We shall now discuss the requirement III of finite energy-momentum, briefly mentioned in the previous section. Clearly, the possibility of using...

Galaxies of 1012 M⊙ at z ≥ 4 Along the K-z Sequence
Stellar masses of galaxies are derived from the K-band (2.2 μm) photometry by taking into account evolution and cosmological effects with the code...

The Luminosity Function of AGN at z ~ 5 ...1
We present a determination of the optical/UV AGN luminosity function and its evolution, based on a large sample of faint (R < 24) QSOs identified in...

A Multiwavelength Survey of Luminous Compact Blue Galaxies from z=3 to z=0
Luminous Compact Blue Galaxies (LCBGs) are small starburst systems that dominate the number density of galaxies at intermediate redshifts. LCBGs have...

The Cosmic Infrared Background (CIRB) and the Role of the “Local Environment of Galaxies” in the Origin of Present-Day Stars
A combination of evidence is presented suggesting that the majority of the stars in today’s galaxies were born during a luminous infrared phase...

The Evolution of Evolved Galaxies
The plethora of high redshift multifrequency surveys currently under way, that were extensively illustrated at this meeting will shortly provide us...

Strange Hosts of Blue Compact Galaxies
Luminous Blue Compact Galaxies (BCGs) have low metallicities, high gas consumption rates and are frequently involved in mergers. These are properties...

Nuclei of Galaxy Bulges Through HST NIR Imaging
We have analyzed the structure of bulges of early-to intermediate-type spirals, on nuclear and global scales, using HST NIR imaging together with...

A Study of Distant Lyα Emitters in Overdense Regions
Recently, we conducted a Very Large Telescope (VLT) large program to search for forming clusters by looking for overdensities of Lyα emitters around...

The Nature of UV-Selected Galaxies in the CDFS
The compilation of the cosmic star formation history suggests that no particular epoch of star formation is seen at redshifts z > 1 (Madau et al....

Large Scale Structure in the Two Micron All Sky Survey
The unprecedented sky coverage and photometric uniformity of the Two Micron All Sky Survey (2MASS) [1] provides a rich resource for obtaining an...

The FORS Deep Field Spectroscopic Survey of High-Redshift Galaxies
The evolution of the properties of galaxy populations with redshift provides important constraints on current models of galaxy formation and...

The Cosmological Evolution of Quasar Black-Hole Masses
The strong correlation observed between black-hole and bulge mass in the local Universe (eg. Magorrian et al. 1998; Gebhardt et al. 2000) directly...

Linear Spectropolarimetry of Young and Other Emission Line Stars
The aim of this article is to demonstrate the useful role that can be played by spectropolarimetric observations of young and evolved emission line...

Interpreting the Hydrogen IR Lines – Impact of Improved Electron Collision Data
We evaluate the effect of variations in the electron-impact excitation cross sections on the non-LTE line formation for hydrogen in early-type stars....
-
Magnetic Fields and Stellar Surface Structures
We discuss the use of high-resolution spectroscopy for studying inhomogeneities on stellar surfaces. Examples of such inhomogeneities include...

Dynamic Model Atmospheres of Cool Giants
Cool giant stars are highly dynamical objects, and complex micro-physical processes play an important role in their extended atmospheres and winds....
