This book consists of invited reviews written by world-renowned experts on the subject of the outskirts of galaxies, an upcoming field which has been understudied so far. These regions are faint and hard to observe, yet hide a tremendous amount of information on the origin and early evolution of galaxies. They thus allow astronomers to address some of the most topical problems, such as gaseous and satellite accretion, radial migration, and merging. The book is published in conjunction with the celebration of the end of the four-year DAGAL project, an EU-funded initial training network, and with a major international conference on the topic held in March 2016 in Toledo. It thus reflects not o...
"This book contains the proceedings of a conference, held on 23-27 April in Tenerife, to discuss recent progress on star formation in galaxies. Presentations took into account advances in related areas such as the structure, dynamics, and evolution of galaxies, their stellar and dark matter components, central black holes as clues to their histories, the physics of the interstellar medium, and the feedback on all spatial scales between star formation and the host galaxy. This volume contains more than a hundred papers on these topics including invited reviews, invited and contributed talks, poster presentations, and two panel discussion sessions. These articles provide an in-depth assessment...
Annotation Papers from a May 2001 conference on the central kpc region in AGN and starbursts examine the connection between an AGN and a starburst, the physics of star formation and non-stellar activity, and the relations between an AGN and the properties of its host galaxy. Progress in imaging technology is reported in papers on the Hubble space telescope observations, X-ray results obtained with new orbiting observatories, and imaging and spectroscopy from ground-based optical/near-infrared telescopes. Numerical simulations of gas dynamics, relationships between massive black holes and AGN activity, and attempts to quantify relations between star formation and gas disks are discussed. Annotation c.

The formation and evolution of galaxies is one of the most important topics in modern astrophysics. Secular evolution refers to the relatively slow dynamical evolution due to internal processes induced by a galaxy's spiral arms, bars, galactic winds, black holes and dark matter haloes. It plays an important role in the evolution of spiral galaxies with major consequences for galactic bulges, the transfer of angular momentum, and the distribution of a galaxy's constituent stars, gas and dust. This internal evolution is in turn the key to understanding and testing cosmological models of galaxy formation and evolution. Based on the twenty-third Winter School of the Canary Islands Institute of Astrophysics, this volume presents reviews from nine world-renowned experts on the observational and theoretical research into secular processes, and what these processes can tell us about the structure and formation of galaxies. The volume provides a firm grounding for graduate students and early career researchers working on galactic dynamics and galaxy evolution.
The borders between galaxies and the almost empty intergalactic medium are ill-defined regions where gas struggles to form stars. The proceedings of IAU Symposium 321 summarize our current understanding of the rarefied universe and prepare for the optimal exploitation of upcoming astronomical instruments. They discuss the most recent advances in the study of the stellar, dust and gas content of galaxy outskirts, going from resolved stellar populations in the Milky Way and in the Local Group to the study of high-redshift systems. Such a broad approach, both in terms of galaxy components and evolutionary epochs, is necessary to take full advantage of the recent discoveries made by facilities at all wavelengths, to deepen our knowledge of the assembly and evolution of these elusive regions and to establish their role within the evolution of galaxies as a whole and their interactions with the surrounding intergalactic medium.
Graduate-level text on galaxy evolution, one of the most popular research topics in astrophysics, with chapters contributed by leading astronomers.
This Atlas and Catalog collects the main data products of the S4G project, including deep mid-IR imaging; total mid-IR magnitudes and color indices; mid-IR isophotal and effective diameters and axis ratios; bulge, disk, and bar scale lengths, characteristic surface bright nesses, and fractional contributions to the total luminosity; and auxiliary data from other sources, such as optical and UV magnitudes and colors, radial velocities, and distance estimates. The quantitative mid-IR parameters will be taken from the various publications of the S4G team, and will be included with appropriate references. Other parameters will be gathered from other published sources.
IAU Transactions XXIIB summarizes the work of the XXIInd General Assembly. The discourses given during the Inaugural and Closing Ceremonies are reproduced in Chapters I and III, respectively. The proceedings of the two sessions of the General Assembly will be found in Chapter II, which includes the Resolutions and the report of the Finance Committee. The Statutes, Bye-Laws and a few working rules of the Union are published in Chapter IV. The Accounts and other aspects of the administration of the Union are recorded in Chapter V, together with the report of the Executive Committee for this last triennium, and provide the permanent record for the Union in the period 1991-1994. This volume also contains the Commission reports from The Hague compiled by the Presidents of the Commissions (Chapter VI). Finally, Chapter VII contains the list of countries adhering to the Union and the alphabetical, geographical and commission membership lists of about 8000 individual members. The IAU still appears to be unique among the scientific Unions in maintaining this category of individual membership which contributes in a crucial way to the spirit and the aims of the Union.
