Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2007-10-22 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stellar populations, the building blocks of galaxies, are direct tracers of a galaxy's star formation history, its chemical enrichment and the assembly of galaxies in the Universe. This last decade has witnessed a revolution in our observations of galaxies; with larger telescopes and new instruments allowing us to look deeper in the Universe, and to study nearby galaxies in greater detail. IAU Symposium 241 reports the considerable progress made in recent years in this topic. Theorists, observers, and researchers of resolved and unresolved stellar populations discuss the ingredients of stellar population models and compare them to new data, forcing theorists to develop more refined models and methods to derive the physical parameters of stellar populations. New results from the Milky Way, the Local Group, and nearby and distant galaxies are presented.

Available in PDF, EPUB and Kindle. Book excerpt: The concept of Stellar Populations has played a fundamental role in astronomy in the last few decades. It was introduced by Walter Baade after he was able to resolve the Andromeda Nebula and its companions into stars when he used red-sensitive plates and realised that there were two fundamentally different Herzsprung-Russell diagrams in our and these nearby galaxies (common stars in the solar neighborhood versus globular clusters). This result was published in two papers in 1944 in volume 100 of the Astrophysical Journal. Subsequent research gave the concept a much firmer basis and at the famous Vatican Symposium of 1957 resulted in a general scheme of the concept and a working hypothesis for idea's on the formation and evolution of the Galaxy. This has been a guiding principle of studies of our and other galaxies for decades. Some years ago it seemed to us appropriate to commemorate Baade's seminal work in 1994, when it would have its 50-th anniversary, and to review its present status and also its role in contempory understanding. While we were in Leiden for an administrative committee, we discussed the matter again and over beers on October 29, 1991 we decided the take the initiative for an IAU Symposium on the subject during the 1994 IAU General Assembly in Den Haag, the Netherlands.

This book was released on 2012-01-12 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: We are living in the golden era of multiwavelength astronomical observations, probing deep areas of the sky. Sophisticated instruments allow us to compare galaxies at high redshifts, when the Universe was only a few hundred millions years old, with the mature nearby galaxies we see today. This is yielding new insights into the mass assembly and the star formation history of galaxies that may, or may not, be compatible with our current theoretical models. IAU Symposium 277 addresses the major open questions concerning the evolution of galaxies, specifically: can we really apply the knowledge gained from low-redshift studies to the high-redshift galaxy populations, given the strong apparent differences in their observed properties? In this volume theorists and observers attempt to reach a common understanding of the puzzles that galaxy research has recently unfolded, largely through the study of galaxy dynamics and their stellar populations at low and high redshifts.

Available in PDF, EPUB and Kindle. Book excerpt: Although low-mass metal-poor galaxies in the local universe have often been proposed as the 'primordial building blocks' in the hierarchical scenario of structure formation, several lines of evidence suggest that this may not be true. Moreover, it is not clear to what extent dwarf galaxies, because they are metal poor and because of their kinematics and structure, can tell us about how star formation proceeded in the early universe. This volume provides an overview and the most recent advances in this debate. IAU Symposium 255 presents the most up-to-date developments in six key areas, including: Population III and metal-free star formation; metal-enrichment, chemical evolution and feedback; explosive events in low-metallicity environments; dust and gas as seeds for metal-poor star formation; metal-poor initial mass functions, stellar evolution and star-formation histories; and low-metallicity star formation in the local universe. This overview is at a level suitable for research astronomers and graduate students.

This book was released on 2004 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: How massive are the largest and smallest nuclear black holes in galaxies? Why are the masses of nuclear black holes proportional to those of their host galaxy bulges? How is nuclear activity triggered? What are the observational signatures of such processes? What are the connections between the active nucleus, stars and interstellar medium in galaxies? Answers to these questions are addressed in this book, which presents a compilation of 191 works covering recent observations from X-rays to radio wavelengths, as well as theoretical modeling of accretion disks, stellar populations and galaxy and black hole evolution. This volume presents the nuclear activity as a phase in the life of a galaxy, which is intimately connected to the evolution of its stars and interstellar medium. It brings together recent developments in topics covering most aspects of galaxy evolution, and is a valuable resource for astronomers and graduate students working in extragalactic astronomy.
