Download or read book From Luminous Hot Stars to Starburst Galaxies written by Peter S. Conti and published by Cambridge University Press. This book was released on 2012-10-04 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Before exploding as supernovae, luminous hot stars live out their lives of a few million years with prodigious outputs of radiation and stellar winds, dramatically affecting both their evolution and environments. This book offers a detailed introduction to the astrophysics of these massive stars and how they contribute to the evolution of galaxies and starburst phenomena. HII galaxies, their connection to starburst galaxies, and the contribution of starburst phenomena to galaxy evolution through superwinds, are thoroughly explored. The authors conclude with the wider cosmological implications, including Population III stars, Lyman break galaxies and gamma-ray bursts, for each of which massive stars are believed to play a crucial role. This book is ideal for graduate students and researchers in astrophysics interested in luminous hot stars and galaxy evolution.

This book was released on 2012-12-06 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Starbursts Triggers Nature and Evolution written by Bruno Guiderdoni and published by Springer. This book was released on 2013-11-11 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Starbursts are regions of unusually rapid star formation, often located in the central parts of galaxies. They differ from more normal regions of star formation in terms of the throughput of mass and the rapidity with which the gas is consumed. In the last twenty years, extensive observational data at most wavelengths have become available on starbursts, but many important issues remain to be addressed, observationally as well as theoretically. How are strong episodes of star formation triggered? What is the quantity of gas converted into stars during bursts? What is the initial mass function of stars in these events? How does the feedback from stars influence the interstellar medium and self-regulate star formation? What is the subsequent chemical and photometric evolution? How do starbursts rule the formation and evolution of galaxies? In recent years, many observational data at different wavelengths (optical, radio, infrared, X-ray) have become available. However, these observations are still fragmentary in the sense that different classes of objects have been observed in different ways, and the coverage is not consistently deep or complete. As a consequence, an overall observational picture of starburst galaxies is missing, and theoretical understanding and modelling have remained highly tentative. The purpose of the school Starbursts: Triggers, Nature, and Evolution was to gather theorists and observers with complementary approaches to the starburst phenomenon, in order to summarize the state-of-the-art of the observations and models, emphasizing the consistency of the various viewpoints.

Available in PDF, EPUB and Kindle. Book excerpt: A major fraction of star formation in the universe occurs in starbursts. These regions of particularly rapid star formation are often located towards the centers of host galaxies. Studies of this kind of star formation at high redshift have produced astonishing results over recent years that were only possible with the latest generation of large ground-based and space telescopes. The papers collected in this volume present these results in the context of the much firmer foundation of star formation in the local universe, and they emphasize all the important topics, from star formation in different environments to the cosmic star formation history.

Download or read book Optical Through Radio Observations of Dust obscured Starbursts and Implications for Massive Galaxy Evolution in the Early Universe written by Sinclaire Miguela Manning and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Far-infrared and (sub)millimeter-bright galaxies are relatively rare in the local Universe, but known to be common at earlier epochs having been observed to dominate the cosmic star formation rate beyond a lookback time of eight billion years, i.e. redshift (z) >1. These systems are distinguished by their high dust mass, as well as the powerful bursts of star formation they undergo, and are capable of forming stars at one thousand times the rate of the Milky Way. In this doctoral thesis, I utilize optical through radio observations to determine the redshifts and physical properties of extreme starbursts, known as dusty star-forming galaxies (DSFGs), at two distinct epochs. I first examine DSFGs around the peak of cosmic star formation at z [approximately equal to] 2, a.k.a. cosmic noon, at which time they contribute roughly half of the Universe’s total star formation. Through this study I ascertain a link between morphology and radio luminosity and the importance of major mergers and interactions in triggering the DSFG phase of galaxy evolution. The sample of sources is selected from the Super-Cluster Assisted Shear Survey (SuperCLASS) and I present a multi-band photometric catalog I assembled covering the 2deg2 survey. This catalog includes optical/mid-infrared photometry and photometric redshifts derived from fitting stellar population synthesis and AGN models to over 375,000 sources. Pushing on to even earlier times, within the first two billion years of the Universe (z>3), I then present a focused analysis of two z [approximately equal to] 4 DSFGs observed at 2-millimeters with the Atacama Large Millimeter/submillimeter Array (ALMA) as part of the Mapping Obscuration to Reionization with ALMA (MORA) survey. The physical characteristics of these two galaxies are consistent with a class of extremely dust-obscured, optically/near-infrared (OIR) invisible DSFGs in the literature. Ultimately, I provide evidence supporting the current theory that “OIR-dark” DSFGs are the progenitors of recently discovered 3

This book was released on 2003-10-31 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides a thorough discussion of the evolution of elemental abundances in the Galaxy taking into account both spatial and temporal variations. For the first time, and in much greater detail, the observed chemical abundances are interpreted in terms of formation and evolution of the Galaxy. Observational constraints like the gas and star formation rate distribution are guiding this interpretation. Readers will find this monograph to be a unique research tool for expert scientists, graduate students, and everyone else who wants to get a deeper understanding of the chemical evolution of the Milky Way and galaxies in general.

Available in PDF, EPUB and Kindle. Book excerpt: The term “chemical evolution of galaxies” refers to the evolution of abundances of chemical species in galaxies, which is due to nuclear processes occurring in stars and to gas flows into and out of galaxies. This book deals with the chemical evolution of galaxies of all morphological types (ellipticals, spirals and irregulars) and stresses the importance of the star formation histories in determining the properties of stellar populations in different galaxies. The topic is approached in a didactical and logical manner via galaxy evolution models which are compared with observational results obtained in the last two decades: The reader is given an introduction to the concept of chemical abundances and learns about the main stellar populations in our Galaxy as well as about the classification of galaxy types and their main observables. In the core of the book, the construction and solution of chemical evolution models are discussed in detail, followed by descriptions and interpretations of observations of the chemical evolution of the Milky Way, spheroidal galaxies, irregular galaxies and of cosmic chemical evolution. The aim of this book is to provide an introduction to students as well as to amend our present ideas in research; the book also summarizes the efforts made by authors in the past several years in order to further future research in the field.

Download or read book Starbursts written by Richard de Grijs and published by Springer Science & Business Media. This book was released on 2006-05-11 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: Starbursts are important features of early galaxy evolution. Many of the distant, high-redshift galaxies we are able to detect are in a starbursting phase, often apparently provoked by a violent gravitational interaction with another galaxy. In fact, if we did not know that major starbursts existed, these conference proceedings testify that we would indeed have difficulties explaining the key properties of the Universe! These conference proceedings cover starbursts from the small-scale star-forming regions in nearby galaxies to galaxy-wide events at high redshifts; one of the major themes of the conference proved to be "scalability", i.e., can we scale up the small-scale events to describe the physics on larger scales. The key outcome of this meeting – and these proceedings – is a resounding "yes" to this fundamental, yet profound question. The enhanced synergy facilitated by the collaboration among observers using cutting-edge ground and space-based facilities, theorists and modellers has made these proceedings a true reflection of the state of the art in this very rapidly evolving field.

Download or read book Evolution of Massive Stars written by D. Vanbeveren and published by Springer. This book was released on 2012-10-14 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: Massive stars occupy an exceptional place in general astrophysics. They trigger many if not all of the important processes in galactic evolution whereas due to their intrinsic brightness, they offer the (only until now) possibility to study the stellar content and stellar behaviour in distant galaxies. The last, say, 25 years, massive stars have been the subject of numerous meetings discussing the influence of massive stars on population synthesis, the number distribution of different types of massive stars, the LBV phenomenon, WR stars, X-ray binaries, stellar winds in massive stars, chemical pecularities in massive stars, supernova explosions of massive stars and the important SN1987A event, the influence of massive stars and chemical evolution of galaxies. It is clear that without a theory of stellar evolution, the study of these topics loses a lot of its significance. Massive star evolution therefore got a chance in these meetings, but rarely as a prime subject. The state of the art, the physical processes and the uncertainties in stellar evolution were barely touched. Even more, the influence of close binaries in all these massive star meetings slowly disappeared the last, say, 13 years without any scientific justification, although a significant fraction of stars occurs in close binaries with periods small enough so that both components will interact during their evolution. Denying the binaries or not discussing their influence on results and conclusions, makes the latter very uncertain or even completely unreliable.
