The idea for another conference on the theme of Infrared Astronomy with Arrays actually goes back to March 1987. At a party held in my home at the end of the Hilo conference, excitement was running high and everyone present was in favor of another meeting. I recall suggesting to Al Fowler that the next meeting could be in Tucson. Despite Al's reply to the effect that Hawaii was a much nicer location, a meeting was held in Tucson three years later. That meeting focussed more on the astrophysics which had been accomplished with the detectors, rather than on techniques and methods. However, it was already apparent in February of 1990 that a new generation of larger m arrays would soon supersede the 64x64 class of devices and so, having just moved from the UK Infrared Telescope unit in Hawaii to join with Eric Becklin in his move to UCLA, it seemed to me that another Hilo-style conference was appropriate, and Eric agreed.
IAU Symposium No. 167 brought together researchers who use CCDs and arrays, designers and manufacturers of CCDs and Array Mosaics and those who write the software to control these devices and to reduce the large amounts of data contained in each frame. At the meeting such topics as plans for applying the new technology to the new large telescopes that have been built recently and those planned in the near future, new developments in infrared arrays, advances and concerns with the use of CCDs in photometry and spectroscopy and the creation of large mosaics in photometry and spectroscopy and the creation of large mosaics of chips which allow larger areas of the sky to be covered in a single frame were discussed. There were sessions devoted to the following topics: New Developments in CCD Technology; New Developments in IR Detector Arrays; Direct Imaging with CCDs and Other Arrays; Spectroscopy with CCDs and Other Arrays; and Large Field Imaging with Array Mosaics. Scientific results of studies made with this technology were covered in the poster sessions. CCD and Array Detectors have become the detectors of choice at all the world's optical observatories. Such instruments on small university and college telescopes have turned these telescopes into instruments that can now do observations which in the past were done only on the largest telescopes. CCDs and Arrays are known as `the people's detector' because of their ability to turn small telescopes into true research instruments. On large telescopes observations can be made of extremely faint and crowded objects that were impossible to observe before the advent of CCD and Array technology. The proceedings of this meeting will be useful to all those who are interested in the design, manufacture and use of CCDs and Arrays for astronomical observations.
This new edition of Infrared and Terahertz Detectors provides a comprehensive overview of infrared and terahertz detector technology, from fundamental science to materials and fabrication techniques. It contains a complete overhaul of the contents including several new chapters and a new section on terahertz detectors and systems. It includes a new tutorial introduction to technical aspects that are fundamental for basic understanding. The other dedicated sections focus on thermal detectors, photon detectors, and focal plane arrays.
With a lively yet rigorous and quantitative approach, this textbook introduces the fundamental topics in optical observational astronomy for undergraduates. It explains the theoretical foundations for observational practices and reviews essential physics to support students' mastery of the subject. Student understanding is strengthened through over 120 exercises and problems.
Astronomy and Astrophysics Abstracts aims to present a comprehensive documen tation of the literature concerning all aspects of astronomy, astrophysies, and their border fields. It is devoted to the recording, summarizing, and indexing of the relevant publications throughout the world. Astronomy and Astrophysics Abstracts is prepared by a special department of the Astronomisches Rechen-Institut under the auspices of the International Astronomical Union. Volume 44 records literature published in 1987 and received before February 15, 1988. Some older documents which we received late and which are not surveyed in earlier volumes are inc1uded too. We acknowledge with thanks contributions of our colleagues all over the world. We also express our gratitude to all organiza tions, observatories, and publishers which provide us with complimentary copies of their publications. Dr. Siegfried Böhme retired from his duties as co-editor of Astronomy and Astro physics Abstracts on December 31, 1987. Since 1950 he partieipated in the biblio graphie work of the institute. He served as a reviewer for the Astronomischer Jahresbericht and became one of the editors of Astronomy and Astrophysics Ab stracts in 1969. After his retirement in 1975 he took care of, particularly, the Russian literature on a voluntary basis for 12 years. It is a pleasure to thank Siegfried Böhme for his valuable contributions. Starting with Volume 33, all the recording, correction, and data processing work was done by means of computers. The recording was done by our technical staff members Ms. Helga Ballmann, Ms. Christiane Jehn, Ms. Monika Kohl, Ms.
