Book Description
The borders between galaxies and the almost empty intergalactic medium are ill-defined regions where gas struggles to form stars. The proceedings of IAU Symposium 321 summarize our current understanding of the rarefied universe and prepare for the optimal exploitation of upcoming astronomical instruments. They discuss the most recent advances in the study of the stellar, dust and gas content of galaxy outskirts, going from resolved stellar populations in the Milky Way and in the Local Group to the study of high-redshift systems. Such a broad approach, both in terms of galaxy components and evolutionary epochs, is necessary to take full advantage of the recent discoveries made by facilities at all wavelengths, to deepen our knowledge of the assembly and evolution of these elusive regions and to establish their role within the evolution of galaxies as a whole and their interactions with the surrounding intergalactic medium.

Book Description
This book contains the proceedings of the International Astronomical Union Colloquium no. 195, held in Torino, Italy in 2004. The meeting investigated the formation of galaxies within a full cosmological context, focusing on the outer regions of galaxy clusters. The observed correlation of optical and radio properties of galaxies with their environment indicates that the formation and evolution of galaxies is intimately linked to the formation of large scale structure. With chapters written by leading authorities in the field, this timely volume investigates the role of the environment in determining the properties of galaxies. It describes the distribution of matter and galaxies on the largest scales in the Universe, the processes of cluster and galaxy formation, their role and interplay. This is a valuable collection of review articles for professional astronomers.

Book Description
This last decade has witnessed a revolution in our observations of galaxies; in particular deep imaging with HST and spectroscopy with 10m-class ground-based telescopes have uncovered many objects that are difficult to place along the Hubble sequence. High resolution spectroscopy of extremely faint objects has enabled the study of the kinematic evolution and, hence, the mass assembly of galaxies to unprecedented look-back times for direct comparison with cosmological structure formation scenarios. Thus, it is now possible to study all three aspects of galaxy evolution - their morphological-dynamical, chemical and spectral evolution out to redshift larger than six, exploring more than 95% of the age of the universe. These Proceedings of the IAU Symposium 235 report the considerable progress made in recent years on galaxy formation and evolution, and look forward to the expected breakthroughs in the domain of remote galaxies, with ALMA, the ELT and the next generation space telescopes.

Book Description
Bulges lie at the heart of most galaxies, the building blocks of our universe. With a selection of reviews and topical presentations, IAU Symposium 245 provides an up-to-date overview of our knowledge on galaxy bulges, and a concise introduction to all current research on the subject. The structure, dynamics, and stellar populations of galaxy bulges, both near and far, are analysed through state-of-the-art observations. The leading models for the formation and evolution of galaxy bulges are described in detail, and the constraints observations put on these are dissected. Particular emphasis is placed on exploring evidence for both hierarchical merging and secular processes. Special attention is also devoted to disentangling the complex web relating galaxy bulges and central supermassive black holes, and on the lessons learned from our exquisite knowledge of the bulge of our own Milky Way. This volume is the best one-stop reference on galaxy bulges currently available.

Book Description
IAU Symposium 262 presents reviews on the current understanding of the theories of stellar evolution, galaxy formation and galaxy evolution. It emphasises what we have learned in the past few years from massive surveys covering large portions of the sky (e.g. SDSS, HDF, UDF, GOODS, COSMOS). Several critical aspects of research on stellar populations deserve further effort in order to be brought in tune with other areas of astrophysical research. The next ten years will see the opening of major observatories that will increase the quality and quantity of astronomical data by orders of magnitude. The expected benefits from these instruments for the study of stellar populations are explored. This critical review of state of the art observational and theoretical work will appeal to all those working on stellar populations, from distant galaxies to local resolved galaxies and galactic star clusters.

Book Description
The goal of IAU Symposium 359 on 'Galaxy Evolution and Feedback across Different Environments' (GALFEED) was to bring together the active galactic nuclei (AGN) and galaxy evolution scientific communities. The AGN phase occurs in most galaxies and critically influences their evolution, so it is important to study the two processes together and for researchers, in both topics, to learn from one another. They ask key questions such as: How do galaxies acquire their gas and how efficiently is it transformed into stars? How is the supermassive black hole in a galaxy center fuelled to become an AGN? What is the main physical mechanism that quenches star formation? How powerful are the stellar and AGN feedback processes in regulating galaxy evolution? And what is the role of the environment on galaxy evolution and AGN triggering? Astronomers engage in these discussions spanning from early galaxies to the present day.

Book Description
IAU Symposium 319 was the largest galaxy evolution meeting at the IAU General Assembly in 2015. This volume presents a summary of the current state of the art in galaxy evolution studies, and provides a perspective on future large spectro-photometric surveys which will become available in the next decade. Topics covered include the emergence of galaxies and their constituent black holes during the first few billion years, the evolving interstellar medium as seen through modern instrumentation like Herschel, Planck and ALMA, and a look ahead to future ground- and space-based instruments that will become the workhorse facilities of the next decade, such as JWST and the SKA precursors. This volume will appeal to those who are interested in the formation and evolution of galaxies over cosmic time, as well as those who are active in developing, or on the science teams for, new astronomical instrumentation.

Book Description
Our comprehension of the assembly and evolution of galaxies has witnessed remarkable advancements in recent years. While the Gaia spacecraft has provided unprecedented knowledge of the Milky Way's assembly, the launch of the James Webb Space Telescope (JWST) has propelled the study of galaxy evolution into an exciting new era. Early discoveries of JWST have revealed high-redshift galaxies that defy our expectations. These conundrums must be resolved through multi-wavelength observations, simulations, and theoretical models as emphasized in this volume, which contains a selection of papers presented at IAU Symposium 377, held about two years after the launch of JWST. These papers showcase studies of galaxy formation, evolution, interaction, chemical abundances and stellar populations from cosmic down to the Milky Way. These proceedings offer an updated view of recent advances and current problems and is suitable for both active researchers in the field and graduate students.

Book Description
Galactic dynamics is fundamental to understanding the formation of galaxies, their internal evolution and their current structure. While galactic dynamics has traditionally focused on the evolution of the stellar components of galaxies, studies over the past two decades have shown that all aspects of galaxy evolution are strongly influenced by the interplay between the dynamics of stars, gas, and dark matter. IAU Symposium 353, is the first major symposium in more than a decade focused on the dynamics of galaxies and stellar systems, covering the recent explosion in the availability of kinematical data both for individual stars in the Milky Way and wide field line-of-sight kinematics for large samples of external galaxies. These proceedings describe recent developments that aim to transform our understanding of the dynamics, structure, formation and evolution of our own host galaxy, the Milky Way, as well as galaxies in the universe at large.

Book Description
Bringing together theorists, observers and instrumentation specialists, IAU Symposium 311 provides an overview of the techniques used to measure the masses of stars, gas and dark matter in galaxies, and explores what these mass determinations tell us about galaxy evolution. A key advance in recent years has been the enrichment of studies of the luminosity evolution of galaxies with determinations of their stellar or total masses from dynamical analyses using stellar populations, stellar or gaseous dynamical models, and weak or strong lensing. This volume addresses some of the fundamental questions in the field: what key observables can be robustly reproduced by the models? How should existing and new instrumentation be optimized for galaxy evolution studies? And, what future observations would be most useful to constrain the models? IAU S311 offers a valuable insight into this rapidly developing and interdisciplinary area of study, for researchers and graduate students.
