Book Description
The study of the evolution of galaxies has made remarkable progress in recent years and is currently undergoing a transformation arising from the application of new observational and theoretical tools. Twenty-one invited reviews, twenty-six contributed papers and 137 poster papers cover the wide variety of recent developments, present new insights and demonstrate the rapid increase in our knowledge about galaxy evolution and formation.

Book Description
Astronomy and Astrophysics Abstracts is devoted to the recording, summarizing and indexing of astronomical publications throughout the world. Two volumes are scheduled to appear per year. Volume 67 records 10,903 papers covering besides the classical fields of astronomy and astrophysics such matters as space flights related to astronomy, lunar and planetary probes and satellites, meteorites and interplanetary matter, X rays and cosmic rays, quasars and pulsars. The abstracts are classified under more than one hundred subject categories thus permitting quick surveying of the bulk of material published on the same topic within six months. For instance, this volume records 119 papers on minor planets, 155 papers on supernovae, and 554 papers on cosmology.

Book Description
Written by one of the leading authorities in the field, this is one of the first book's to describe one of today's most important problems in cosmology - the formation of galaxies. The book tackles this great puzzle by discusses the beginnings of the process from cosmological observations and calculations, considers the broad features of galaxies that we need to explain and what we know of their later history. The author compares the competing theories for galaxy formation and considers the progress expected from new generations of powerful telescopes both on earth and in space. An intriguing text on one of today's greatest and most profound puzzles.

Book Description
This book is based partly on a. lecture course given at the University of Tri este, but mostly on my own research experience in the field of galactic chemical evolution. The subject of galactic chemical evolution was started and developed by Beat rice Tinsley in the seventies and now is a flourishing subject. This book is dedi cated to the chemical evolution of our Galaxy and aims at giving an up-to-date review of what we have learned since Tinsley's pioneering efforts. At the time of writing, in fact, books of this kind were not available with the exception of the excellent book by Bernard Pagel on "Nucleosynthesis and Chemical Evolution of Galaxies" (Cambridge University Press, 1997), and the subject of galactic chem ical evolution has appeared only as short chapters in books devoted to other subjects. Therefore, I felt that a book of this kind could be useful. The book summarizes the observational facts which allow us to reconstruct the chemical history of our Galaxy, in particular the abundances in stars and in terstellar medium; in the last decade, a great deal of observational work, mostly abundance determinations in stars in the solar vicinity, has shed light on the pro duction and distribution of chemical elements. Even more recently more abun dance data have accumulated for external galaxies at both low and high redshift, thus providing precious information on the chemical evolution of different types of galaxies and on the early stages of galaxy evolution.

Book Description
In this dissertation, I present a series of studies on the low surface brightness outskirts of galaxies, which contain a record of tidal interactions and secular evolution processes. Each study utilized new deep imaging from the Burrell Schmidt Telescope in either broadband filters or narrow-band filters targeting Halpha emission. Regarding tidal interactions, I present a study of the M96 Group (or Leo I Group), as well as deep imaging of the interacting pair M51. I find that the M96 Group’s intragroup light (IGL) consists of only three faint linear streams. I find no stellar counterpart to the group’s H I ring, unusual if it were collisional in origin, and few signs of interaction among its four most massive members, implying a very calm tidal history. In M51, I discover several extremely diffuse plumes of starlight, yet find no stellar counterpart to its H I tail. Additionally, I measure red (B - V ~ 0.8) colors in all of its most extended tidal features, implying dominantly old populations and thus a lack of interaction-induced extended star formation. Regarding secular evolution, I conduct a detailed photometric study of three nearby galaxies’ outer disks. Each outer disk lacks both ongoing star formation and the spiral structure necessary to migrate stars from the inner disk, hence it is unclear how these red outer disks formed. Finally, I conduct a study of the H II regions and diffuse ionized gas (DIG) throughout the M101 Group, to determine whether star formation in low density environments occupies a distinct physical regime from its high density counterpart. I find that the distribution of Halpha/FUV flux ratios (a tracer of the initial mass function, IMF) is constant among all H II region populations throughout the group. Also, the Halpha/FUV ratio in the DIG appears tied only to the local intensity of star formation, leaving little room for changing star formation physics. In total, this dissertation shows that tidal interactions in low-density groups may be infrequent, raises questions about the origin of extended red outer disks, and shows that star formation physics change little with local mass density.

Book Description
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., their Origins, Evolution, and Applications in astronomy. The Origins of galaxy scaling relations still escape our full understanding.
