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.

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.

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.

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.

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
