Available in PDF, EPUB and Kindle. Book excerpt: The next major step in millimetre astronomy, and one of the highest-priority items in radio astronomy today, is a large millimetre array with a collecting area 2 of up to 10 000 m . A project of this scale will almost certainly require inter national collaboration, at least within Europe, and possibly with other major partners elsewhere. In order to establish a focal point for this project within Europe, a study has been undertaken by the Institut de Radio Astronomie Mil Ii met rique (IRAM), the European Southern Observatory (ESO), The Onsala Space Observatory (OSO), and The Netherlands Foundation for Research in Astronomy (NFRA). In the context of this project, a workshop attended by some 100 participants was held at ESO Garching on December 11-13, 1995 to discuss the scientific advances such an array will make possible. Throughout the three days of the workshop the strong enthusiasm for the concept of a large millimetre array in the southern hemisphere (the Large South ern Array, or LSA) was obvious, and it became clear that such a facility would have a profound impact on almost all areas of observational astrophysics. It was particularly clear that, since their main science drivers (cosmology, and the origins of galaxies, stars and planets) are the same, and their angular resolutions and sensitivities similar, the LSA and the VLT would strongly complement each other.

This book was released on 2022-12-05 with total page 744 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides the first comprehensive historical account of the evolution of scientific traditions in astronomy, astrophysics, and the space sciences within the Max Planck Society. Structured with in-depth archival research, interviews with protagonists, unpublished photographs, and an extensive bibliography, it follows a unique history: from the post-war relaunch of physical sciences in West Germany, to the spectacular developments and successes of cosmic sciences in the second half of the 20th century, up to the emergence of multi-messenger astronomy. It reveals how the Society acquired national and international acclaim in becoming one of the world’s most productive research organizations in these fields.

Available in PDF, EPUB and Kindle. Book excerpt: Annotation This collection from the November 2000 workshop reviews the state of the art in observatory site testing methods and instruments across the entire ground-based optical, infrared, and (sub)mm wavelength ranges. The 72 papers investigate the physical mechanisms of atmospheric turbulence, measuring instruments in the visible range, site characterization and atmospheric transparency in the (sub)mm range, tropospheric phase stability, forecasting, site surveys, astroclimatic stations, and phase correction. Specific topics include site monitoring for extremely large telescopes, atmospheric turbulence profiles deduced from solar limb observations, and a comparison of the Pampa La Bola and Llano de Chajnator sites in northern Chile.

Download or read book The Mass of Galaxies at Low and High Redshift written by Ralf Bender and published by Springer Science & Business Media. This book was released on 2003-01-23 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measuring the masses of galaxies as a function of redshift is perhaps one of the most challenging open issues in current astronomical research. The evolution of the baryonic and dark matter components of galaxies is not only a critical test of the hierarchical formation paradigm, but ultimately also provides new clues on the complex interplay between star formation, the cooling and heating of gas and galaxy merging processes. This book reviews current techniques to measure the baryonic (stellar) and dark masses of nearby galaxies, and focusses on ongoing attempts to measure theses same quantities in galaxies at higher and higher redshifts. It also gives room to future perspectives, with special emphasis on new survey projects and satellite missions.
Download or read book Spectrum Management for Science in the 21st Century written by National Research Council and published by National Academies Press. This book was released on 2010-02-25 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radio observations of the cosmos are gathered by geoscientists using complex earth-orbiting satellites and ground-based equipment, and by radio astronomers using large ground-based radio telescopes. Signals from natural radio emissions are extremely weak, and the equipment used to measure them is becoming ever-more sophisticated and sensitive. The radio spectrum is also being used by radiating, or "active," services, ranging from aircraft radars to rapidly expanding consumer services such as cellular telephones and wireless internet. These valuable active services transmit radio waves and thereby potentially interfere with the receive-only, or "passive," scientific services. Transmitters for the active services create an artificial "electronic fog" which can cause confusion, and, in severe cases, totally blinds the passive receivers. Both the active and the passive services are increasing their use of the spectrum, and so the potential for interference, already strong, is also increasing. This book addresses the tension between the active services' demand for greater spectrum use and the passive users' need for quiet spectrum. The included recommendations provide a pathway for putting in place the regulatory mechanisms and associated supporting research activities necessary to meet the demands of both users.

Book excerpt: "These proceedings of an international meeting held May 2007 in Girdwood, Alaska, USA provide a comprehensive overview of recent theoretical and observational work on the nature of extragalactic jets, from parsec to kiloparsec scales. Special emphasis is given to the interaction of jets with their environment and to the insights this interaction can provide. The invited reviews, contributed talks, and poster sessions form a detailed summary of the latest findings, as well as illustrate outstanding questions that remain to be resolved. This book is suitable for researchers and graduate students. The origin and evolution of highly collimated and highly energetic outflows from the nuclei of some galaxies remains, after over 30 years of intensive study, and enigmatic process. We still do not know how these jets are collimated, or what they contain beyond relativistic particles and magnetic fields, much less how they come to be in the first place. If we could unravel the mystery of their origins, then it is clear that new and significant constraints could also be placed on the origin and evolution of the "central engine," presumably a massive black hole, that creates them. This is turn would give rise to new constraints on the formation and evolution of the parent galaxies and their environment. The quest for insights into the nature of these objects has always been made difficult by the last of information conveyed by their simple power law radiation spectrum, and so much of the information gained must be inferential. However, the hope remains that by gaining an understanding of the interaction of these objects with their environment we may be able to deduce the key parameters of the jets themselves. This strategy of working from "the outside in" is showing increasing promise as higher resolution observations with increasing sensitivity are being made over increased coverage in wavelength, especially as these are cast against results from sophisticated theoretical calculations that include three-dimensional MHD simulations."--Publisher's website
