Book Description
This report details work done in a project involving spectroscopic studies, including data analysis and modeling, of star-formation regions using an ensemble of archival space-based data including some from the Infrared Space Observatory's Long Wavelength Spectrometer and Short Wavelength Spectrometer, and other spectroscopic databases. We will include four kinds of regions: (1) disks around more evolved objects; (2) young, low or high mass pre-main sequence stars in star-formation regions; (3) star formation in external, bright IR (infrared) galaxies; and (4) the galactic center. During this period, work proceeded fully on track and on time. Details on workshops and conferences attended and research results are presented. A preprint article entitled 'The Far Infrared Lines of OH as Molecular Cloud Diagnostics' is included as an appendix. Smith, Howard A. and Hasan, Hashima (Technical Monitor) Goddard Space Flight Center

Book Description
The last major conference on infrared astronomy was the IAU Symposium No. 96 in June 1980. Since then, the discipline has continued to mature and to contribute to all branches of astrophysics. One particular area of growth has been in spectroscopic capabilities at all infrared wavelengths. The purpose of the Symposium in Toledo was to review the scientific questions to be addressed via infrared spectroscopy and to provide, in the proceedings, a useful summary of the field. The sensitivity of infrared spectroscopic observations is still generally limited by detector characteristics or by thermal background radiation. However in recent years improvements in detector technology together with developments in spectroscopic instrumentation have made possible both quite detailed spectroscopy of the brighter members of many classes of galactic sources and also begun to open up some infrared spectroscopy of extragalactic sources. The potential of the field in the next decade or two is clear. The lRAS mission has completed one of the pre-requisites, namely an all-sky photometric survey. Major space missions utilising cryogenic infrared telescopes have been approved in Europe (ISO) and seem likely in the USA (SIRTF); plans for space submillimeter telescopes are firming up. On the ground large telescopes optimized for infrared observations are now in operation at high altitude sites and specialized submillimeter facilities are under construction. The particular advantages of planned, very large telescopes for infrared observations are widely accepted.

Book Description
Recent advances in the instrumentation used to observe star forming regions in both our own Milky Way and in external galaxies have transformed the subject from a phenomenological pursuit into an increasingly unified, physical science. High resolution centimetre, millimetre, infrared, and optical studies of local star forming clouds have allowed us to probe the physics of star formation down to spatial scales approaching those of the solar system. These developments make it possible to better constrain the basic physical processes underlying star formation itself. At the same time, these new instruments have placed extragalactic studies on a footing detailed enough to allow comparison with star forming regions within our own galaxy. This revolution means that we will soon be able to link the physics of local star forming regions to the global star forming properties of galaxies. The entire structure of this NATO Advanced Study Institute was designed to explore this new view of the subject. This Institute on "Galactic and Extragalactic Star Formation" was held from June 21 -July 4, 1987 at the Conference Centre in the village of Whistler, British Columbia, Canada. The informal atmosphere of this lovely mountain resort stim ulated many valuable scientific exchanges. The Institute was funded by a major grant from NATO Scientific Affairs. Additional financial and I.I1oral assistance was provided by the Canadian Institute for Theoretical Astrophysics (CITA) and Mc Master University.

Book Description
This book provides a review of the work in progress on the infrared spectral region of stars. The most important previous mission, the Infrared Astronomy Satellite (IRAS) was launched in 1983. Although it was only operating for one year, in that time it surveyed the whole sky for infrared emitters of many different kinds providing a fundamental catalogue of thousands of objects. As a consequence of its success, a new mission to observe the infrared sky is being planned. The Infrared Space Observatory (ISO) is scheduled for a launch in May 1993. It should add substantially to our knowledge of the stars. The volume is based on the proceedings of an international conference held in Montpellier, France. It provided an excellent forum for the experts in the field to get together and evaluate the status of current knowledge and analyse the instrumentation.

Book Description
"In November 2005, the 2nd annual Spitzer Science Center international conference was held in Pasadena, California, USA. The purpose of this conference was to provide an overview of the role that infrared imaging and spectroscopy play in revealing the nature of astrophysical environments. Particular emphasis was given to how mid-infrared spectroscopy can disentangle the contribution of star-formation and active galactic nuclei to the bolometric luminosity of individual extragalactic sources. The conference was motivated by the wealth of data from the first two years of operation of the Spitzer Space Telescope but included contributions from ground-based imaging and spectroscopy as well. A wide variety of astrophysical objects were covered, ranging from star-forming regions in local galaxies, including our own, to high redshift galaxies at the epoch of reionization. The conference included 14 review talks, 45 contributed talks, 112 posters, and a brainstorming discussion on what Spitzer should do next. The conference and these proceedings clearly highlight the fundamental role that the infrared plays in providing a more complete picture of galaxy formation and evolution over cosmic time." -- publisher's website.

Book Description
The enormously powerful phenomena of starbursts are examined in this book. These spectacular star-forming events are seen on large scales in some galaxies, often triggered by galactic interactions. An intriguing implication of starburst research is that active galactic nuclei (AGN) may not be powered by accreting black holes. Instead theories are presented where compact powerhouses of dust-enshrouded star formation lie at the core of AGN, with supernovae exploding roughly once per year within massive nuclear concentrations of gas. This book collects articles from a timely international conference in Elba, Italy, in 1992; these comprise a thorough review of the most important developments in galactic-scale star formation since the starburst revolution of the late 1980s. This text will introduce graduate students to this exciting area and keep experts apace with rapid developments in it.
