Book Description
Astronomers are at a crucial point in our understanding of the Milky Way. Deciphering the assembly history of our galaxy requires detailed mapping of the structure, dynamics, chemical composition, and age distribution of its stellar populations. In the last decade, astrometric, spectroscopic, photometric, and asteroseismic surveys have started to unveil the inner- and outermost regions of the Milky Way. IAU Symposium 334 explores the still open questions and focusses on the concepts emerging from the analysis of these large, new, and complex datasets. This volume presents a summary of these topics, including the current novel data and the challenges they already pose to modeling, before Gaia end-of-mission, PLATO, and large spectroscopic surveys such as WEAVE and 4MOST are about to start. Graduate students and researchers will learn that, in this golden era of galactic archaeology, we are about to rediscover our galaxy.

Book Description
Astrophysical masers, naturally occurring microwave and radio-wave emissions, provide an important tool to investigate astrophysical environments. Several thousand maser sources have been observed in the interstellar medium and star formation regions, in the expanding winds from evolved stars, in the compressed shells of supernovae remnants, in comets and in the centers of galaxies. Masers are also useful for studying the structure and dynamics of our own galaxy, while masers in other galaxies are now used for cosmological studies and studies of galactic nuclei. This volume contains the latest research on the topic as presented at IAU Symposium 242, only the third international symposium on astrophysical masers. Over 125 astronomers from 18 different countries gathered in Alice Spring, Australia, for discussions on maser research.

Book Description
New telescopes spanning the full electromagnetic spectrum have enabled the study of supernovae (SNe) and supernova remnants (SNRs) to advance at a breathtaking pace. Automated synoptic surveys have increased the detection rate of supernovae by more than an order of magnitude and have led to the discovery of highly unusual supernovae. Observations of gamma-ray emission from SNRs with ground-based Cherenkov telescopes and the Fermi telescope have spawned new insights into particle acceleration in supernova shocks. Far-infrared observations from the Spitzer and Herschel observatories have told us much about the properties and fate of dust grains in SNe and SNRs. Work with satellite-borne Chandra and XMM-Newton telescopes and ground-based radio and optical telescopes reveal signatures of supernova interaction with their surrounding medium, their progenitor life history and of the ecosystems of their host galaxies. IAU Symposium 296 covers all these advances, focusing on the interactions of supernovae with their environments.

Book Description
Astronomy in Focus presents the most relevant contributions from the Focus Meetings included during the XXX IAU General Assembly held in Vienna, Austria, from 20-31 August 2018. Focus meetings are proposed by groups of scientists with aims to promote cross-disciplinary interactions while maintaining a well-defined focus on a particular topic. They usually address a new scientific area or an emerging field that is not well, or in some cases not at all, represented under the IAU's existing Commission structure. The XXX IAU General Assembly included six scientific symposia, a special symposium focused on the IAU's centenary and fifteen Focus Meetings. The latter comprised twelve scientific Focus Meetings plus two on the mission and activities of the IAU Offices of Astronomy Outreach and Astronomy for Development and the final one promoted by the Working Group on Global Coordination of Ground and Space Astrophysics.

Book Description
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.

Book Description
In Southern Gems, Stephen James O'Meara makes a detour beneath the southern skies, presenting a fresh list of 120 deep-sky objects for southern hemisphere stargazers to observe. Showcasing many exceptional objects catalogued by the pioneering observer James Dunlop, known as the 'Messier of the southern skies', all are visible through small- to moderate-sized telescopes or binoculars under dark skies. The list features some of the blackest dark nebulae, icy blue planetary nebulae and magnificent galaxies of all types. Each object is accompanied by beautiful photographs and sketches, original finder charts, visual histories and up-to-date astrophysical background information. Whether you live in the southern hemisphere or are just visiting, this new Deep-Sky Companion will make a perfect observing partner, whatever your background. There is no other southern sky guide like it on the market.

Book Description
This book presents an up-to-date collection of reviews and contributed articles in the field of ultraviolet astronomy. Its content has been mainly motivated by the recent access to the rest frame UV light of distant red galaxies, gained through large optical facilities. This driveway has derived in a renewed interest on the stars that presumably dominate or have important effects on the integrated UV properties of evolved systems of the nearby and faraway Universe. The topics included in this volume extend from the fresh spectroscopic analyses of high redshift early-type galaxies observed with the 8-10m class telescopes to the fundamental outcomes from various satellites, from the long-lived International Ultraviolet Explorer to current facilities, such as the Galaxy Evolution Explorer. This is one of the few volumes published in recent years devoted to UV astronomical research and the only one dedicated to the properties of evolved stellar populations at these wavelengths. This contemporary panorama will be an invaluable resource in the preparation of the next planned space missions, such as the World Space Observatory and the Ultraviolet Imaging Telescope.
