Book Synopsis The Evolution of Galaxies by : Marc Sauvage
Download or read book The Evolution of Galaxies written by Marc Sauvage and published by Springer Science & Business Media. This book was released on 2002-07-31 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: Galaxies have a history. This has become clear from recent sky surveys which have shown that distant galaxies, formed early in the life of the Universe, differ from the nearby ones. New observational windows at ultraviolet, infrared and millimetric wavelengths (provided by ROSAT, IRAM, IUE, IRAS, ISO) have revealed that galaxies contain a wealth of components: very hot gas, atomic hydrogen, molecules, dust, dark matter ... A significant advance is expected due to new instruments (VLT, FIRST, XMM) which will allow one to explore the most distant Universe. Three Euroconferences have been planned to punctuate this new epoch in galactic research, bringing together specialists in various fields of Astronomy. The first one, held in Granada (Spain) in May 2000, addressed the observational clues. The second one took place in October 2001 in St Denis de la Réunion (France) and reviewed the basic building blocks and small-scale processes in galaxy evolution. The third one will take place in July 2002 in Kiel (Germany) and will be devoted to the overall modelling of galaxy evolution. This book contains the proceedings of the second conference. It is suitable for researchers and PhD students in Astrophysics.
Book Synopsis Galaxy Evolution in Groups and Clusters by : Catarina Lobo
Download or read book Galaxy Evolution in Groups and Clusters written by Catarina Lobo and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Galaxy groups and clusters provide excellent laboratories for studying galaxy properties in different environments and at different look-back times. In particular, the recent detections of high-redshift cluster candidates, only possible with the current high-technology instrumentation, add a new dimension to the problem. Along with the ever increasing computing power and sophisticated algorithms to model clusters of galaxies, it may help us to understand the origins of today's groups and clusters, as well as of their member galaxies. These workshop proceedings provide a snapshot of the current research in this subject, covering the observations, theory and numerical simulations relevant to galaxy evolution in groups and clusters. In this book, intended primarily to researchers in the field, particular emphasis is given to the recent impressive progress in the field, on important new results, and on the future prospects and open questions to be tackled.

Book Synopsis Evolution of early-type galaxies at z~1 by : Raphaël Gobat
Download or read book Evolution of early-type galaxies at z~1 written by Raphaël Gobat and published by Sudwestdeutscher Verlag Fur Hochschulschriften AG. This book was released on 2009 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of the spectroscopic, photometric and morphological properties of early-type galaxies, especially at high redshift and over a range of environmental densities, allows to put constraints on galaxy formation and evolution models. In particular, the presence of old passive stellar populations up to z 1.5 pushes further back the epoch of the last significant star formation episode in massive early-type galaxies. This book presents a study of the star formation history in these high redshift early-type galaxies, in both cluster and field environments, and the novel method used to reconstruct it.

Book Synopsis On the Formation and Evolution of Early-type Galaxies by : Christina Cambouri Williams
Download or read book On the Formation and Evolution of Early-type Galaxies written by Christina Cambouri Williams and published by . This book was released on 2014 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Galaxies in the local Universe are characterized by blue, star-forming disk galaxies, and red, massive early-type galaxies (ETGs) whose star-formation has been quenched early in the Universe's history. The ETGs are relics of the evolutionary processes that transform galaxies over cosmic time, but currently we still lack a comprehensive understanding of their evolution. An important link in the evolution of ETGs is that the first quenched galaxies (z~2) are both the most massive, and most compact, suggesting a physical connection between high stellar density and efficient, rapid cessation of star-formation. In this dissertation, I seek insight into the formation and evolution of ETGs, in particular the physical mechanisms that quench star-formation, through analysis of their star-forming progenitors at high-redshift. First, I present a clustering analysis of rare and extreme sub-millimeter galaxies, thought to be gas-rich mergers of massive star-forming galaxies, and find that their clustering is weaker than expected for the progenitors of the massive ETGs in the center of z~0 clusters. Second, I identify a population of likely progenitors of the compact ETGs at z~2 among compact star-forming galaxies at z>3, and found that the stellar populations in these compact LBGs may be older than that of coexistent LBG that are normal in terms of mass and size (i.e. not compact). The morphologies of these compact LBG, as well as the compact ETGs at z~2, appear inconsistent with the predictions from simulations of gas-rich mergers, at least to the extent that current simulations describe real gas-rich mergers. Finally, I study the conditions in the interstellar medium of a sample of these compact progenitors using rest-frame ultra-violet spectroscopy. I find faster outflows, and large populations of metal-rich massive stars in the compact progenitors compared to normal star-forming galaxies at the same epoch and stellar mass, and present evidence that winds from these massive stars are energizing the interstellar medium of these compact galaxies. I conclude with a discussion of these findings in the context of star-formation quenching in massive high-redshift galaxies, and outline future directions which may further illuminate the nature of quenching at high-redshift.

Download or read book Galaxies written by Francoise Combes and published by John Wiley & Sons. This book was released on 2021-04-27 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Galaxies are vast ensembles of stars, gas and dust, embedded in dark matter halos. They are the basic building blocks of the Universe, gathered in groups, clusters and super-clusters. They exist in many forms, either as spheroids or disks. Classifications, such as the Hubble sequence (based on mass concentration and gas fraction) and the colormagnitude diagram (which separates a blue cloud from a red sequence) help to understand their formation and evolution. Galaxies spend a large part of their lives in the blue cloud, forming stars as spiral or dwarf galaxies. Then, via a mechanism that is still unclear, they stop forming stars and quietly end in the red sequence, as spheroids. This transformation may be due to galaxy interactions, or because of the feedback of active nuclei, through the energy released by their central super-massive black holes. These mechanisms could explain the history of cosmic star formation, the rate of which was far greater in the first half of the Universes life. Galaxies delves into all of these surrounding subjects in six chapters written by dedicated, specialist astronomers and researchers in the field, from their numerical simulations to their evolutions.
