Description : Theideatocelebrate50yearsoftheSalpeterIMFoccurredduringtherecent IAU General Assembly in Sydney, Australia. Indeed, it was from Australia that in July 1954 Ed Salpeter submitted his famous paper "The Luminosity Function and Stellar Evolution" with the rst derivation of the empirical stellar IMF. This contribution was to become one of the most famous astrophysics papers of the last 50 years. Here, Ed Salpeter introduced the terms "original mass function" and "original luminosity function", and estimated the pro- bility for the creation of stars of given mass at a particular time, now known as the "Salpeter Initial Mass Function", or IMF. The paper was written at the Australian National University in Canberra on leave of absence from Cornell University (USA) and was published in 1955 as 7 page note in the Astroph- ical Journal Vol. 121, page 161. To celabrate the 50th anniversary of the IMF, along with Ed Salpeter’s 80th birthday, we have organized a special meeting that brought together scientists involved in the empirical determination of this fundamental quantity in a va- ety of astrophysical contexts and other scientists fascinated by the deep imp- cations of the IMF on star formation theories, on the physical conditions of the gas before and after star formation, and on galactic evolution and cosmology. The meeting took place in one of the most beautiful spots of the Tuscan countryside, far from the noise and haste of everyday life.

Description : This volume offers a background in modern high spatial resolution techniques, illustrating how such methods have impacted on our understanding of young stars. It provides hands-on insight into observing from space as well as the ground, the use of interferometers at millimeter and infrared wavelengths, image analysis and spectral diagnostic techniques, and High Angular Resolution studies of the inner regions of circumstellar disks that play a fundamental role in jet launching.

Description : 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.

Description : This is an unusual book, combining as it does papers on astrobiology, history of astronomy and sundials, but—after all—Woody Sullivan is an unusual man. In late 2003 I spent two fruitful and enjoyable months in the Astronomy Department at the University of Washington (UW) working on archival material accumulated over the decades by Woody, for a book we will co-author with Jessica Chapman on the early development of Australian astronomy. The only serious intellectual distraction I faced during this period was planning for an IAU colloquium on transits of Venus scheduled for June 2004 in England, where I was down to present the ‘Cook’ paper. I knew Woody was also interested in transits (and, indeed, anything remotely connected with shadows—see his paper on page 3), and in discussing the Preston meeting with him it transpired that his 60th birthday was timed to occur just one week later. This was where the seed of ‘Woodfest’ began to germinate. Why not invite friends and colleagues to join Woody in Seattle and celebrate this proud event? I put the idea to Woody and others at UW, they liked it, and ‘Woodfest’ was born.

Description : The Cologne-Bonn-Zermatt symposium is a well established series of conferences, occurring on a 5-year cycle, on the dense interstellar medium and related topics. The main results constitute valuable proceedings that offer everyone working in this field an authoritative and comprehensive source of reference.

Description : "These are the proceedings of the international conference "Formation and Evolution of Galaxy Disks" organized by the Specola Vaticana (the Vatican Observatory). The meeting hosted 198 participants from 26 countries. The program consisted of 61 talks and about 130 poster papers. In 2000 the Vatican Observatory organized a conference on Galaxy Disks and Disk Galaxies, the proceedings of which were published in ASP Conference Series Vol. 230. Since that time, a great amount of work has been done in this very active field. October 2007 was deemed an appropriate time to hold another similar conference where outstanding senior and junior astronomers in this field could air new results. The conference was focused on the formation and evolution of galaxy disks and covered the following topics: (1) properties of nearby galaxy disks; (2) interstellar medium, star formation, and chemical evolution; (3) disk edges, outskirts, and environment; (4) accretion onto disks, interactions, and mergers; (5) secular evolution of disks and bar/spiral driven evolution of galaxies; (6) evolution of disk structural properties; and (7) disk formation in a hierarchical universe. This books is of interest for researchers in extragalactic astronomy. It presents an overview of the relevant results and the progress made in the field in the last seven years."--Publisher's website.
