The volume consists of up-to-date reviews and a selection of
contributed papers on subjects including the structure and physical
properties of molecular clouds, their role in the star formation
process, their dust and chemical properties, molecular cloud
surveys of the Milky Way, cloud evolution, problems in cloud mass
determinations (a panel discussion and review), the CO properties
of external galaxies, nuclei of galaxies as revealed by molecular
observations, and galactic spiral structure as reflected by
molecular cloud distributions. The abstracts of poster papers on
these topics presented at the conference are also included. This
book is both a valuable reference and a compendium of current
knowledge in this field. It should be of special interest to all
students and researchers who work on the physics of star formation,
the interstellar medium, molecular clouds and galactic structure.
Meant as a review for students of astrophysics and particle
physics, this book contains a selection of survey articles and
seminar reports on "high energy cosmology." Included are
contributions on topics ranging from classical cosmology, large
scale structure, and primordial nucleosynthesis to quantum
cosmology, covering both the theoretical aspects and the most
important observations.
This book begins with a very readable survey "The Sun Today" by
J.-C. Pecker. It is followed by thorough reviews from leading
experts covering theory and observations. The focus shifts from the
solar core, studied via neutrino emissions and helioseismology,
through the interface regions where it is believed the large-scale
magnetic fields are generated, to the corona, where most of the
high temperature phenomena characteristic of this region may be
studied directly. As energetic particles play such a vigorous role
in this part of the sun, a separate session was devoted to their
transport and storage in the corona.
Bill Cassidy has led meteorite recovery expeditions in the
Antarctic for many years. His searches have resulted in the
collection of thousands of meteorite specimens from the ice. This
fascinating story is a first-hand account of his field experiences
on the US Antarctic Search for Meteorites Project, which he carried
out as part of an international team of scientists. Cassidy
describes this hugely successful field program in Antarctica and
its influence on our understanding of the moon, Mars and the
asteroid belt. In this 2003 book, he describes the hardships and
dangers of fieldwork in a hostile environment, as well as the
appreciation he developed for the beauty of the place. In the final
chapters he speculates on the results of the trips and the future
research they might lead to.
This ESO workshop, which took place in September 1995 on a topic
that at a first glance could be considered rather specialized,
attracted an unpre dictably large number of scientists. This
certainly reflects the importance of this field, which has lost its
seemingly esoteric character, in a wider astro physical context. To
give as much room as possible in these proceedings to the targeted
talks, no presentation of the Very Large Telescope Observatory has
been included. All readers missing such a presentation are reminded
that up-to date in-depth information about the VLT status is
available electronically.1 Papers were given concerning
observations in the entire electromagnetic spectrum from x-rays to
mm-waves, i.e., exceeding 22 octaves in frequency. The VLT as any
ground-based optical observatory can only address at best 7
octaves. Nevertheless the VLT, most likely the only ground-based
observa tory specifically designed to access all these 7 octaves of
the electromagnetic spectrum practically in parallel, will
undoubtedly be a tool of extreme value to this field.
A detailed study of the science, engineering and applications of
terahertz technology, based on room-temperature solid-state
devices, which are seen as the key technology for wider
applications in this frequency range. The relative merits of
electronic and optical devices are discussed and new device
principles identified. Issues of terahertz circuit design,
implementation and measurement are complemented by chapters on
current and future applications in communications, sensing and
remote surveillance. Audience: The unique coverage of all aspects
of terahertz technology will appeal to both new and established
workers in the field, as well as providing a survey for the
interested reader.
This book was conceived to commemorate the continuing success of
the guest observer program for the International Ultraviolet
Explorer (IUE) satellite observatory. It is also hoped that this
volume will serve as a useful tutorial for those pursuing research
in related fields with future space observatories. As the IUE has
been the product of the three-way collaboration between the U.S.
National Aeronautics and Space Administration (NASA), European
Space Agency (ESA) and the British Engineering and Research Council
(SERC), so is this book the fruit of the collaboration of the
American and European participants in the IUE. As such, it is a
testimony to timely international cooperation and sharing of
resources that open up new possibilities. The IUE spacecraft was
launched on the 26th of January in 1978 into a geosynchronous orbit
over the Atlantic Ocean. The scientific operations of the IUE are
performed for 16 hours a day from Goddard Space Flight Center in
Greenbelt, Maryland, U.S.A, and for 8 hours a day from ESA
Villafranca Satellite Tracking Station near Madrid, Spain.
Written in a pedagogical way, the articles in this book address
graduate students as well as researchers and are well suited for
seminar work. Subjects at the forefront of nuclear research,
bordering other areas of many-particle physics, such as electron
scattering at different energy scales, new physics with radioactive
beams, multifragmentation, relativistic nuclear physics, high spin
nuclear problems, chaos, the role of the continuum in nuclear
physics or recent calculations with the shell model are presented.
It is felt that the topics treated in this book address the main
future lines of development of nuclear physics.
The Solar and Heliospheric Observatory (SOHO) is a joint ESA/NASA
mission to study the Sun, from its deep core to the outer corona,
and the solar wind. SOHO was launched on 2 December 1995 and was
inserted into a halo orbit around the L1 Lagrangian point on 14
February 1996. From this vantage point it is continuously
monitoring the Sun, the heliosphere, and the solar wind particles
that stream toward the Earth. Nominal operations of the SOHO
mission started in April 1996 after commissioning of the spacecraft
and the scientific payload. Detailed descriptions of the twelve
instruments, which represent the most comprehensive set of solar
and heliospheric instruments ever developed and placed on the same
platform, can be found in "The SOHO" "Mission" ("Solar Physics,"
Vol. 162, Nos. 1-2, 1995).
This volume contains papers reporting the first scientific results
from the SOHO mission as well as descriptions of the in-flight
performance of some of the instruments, published in two parts of a
"Solar Physics" special (Part I in "Solar Physics," Vol. 170, No.
1; Part II in "Solar Physics," Vol. 175, No. 2). Unique data from
the three helioseismology instruments (GOLF, VIRGO, MDI/SOI)
provide new insights into the structure and dynamics of the solar
interior, from the deep core to the outermost layers of the
convection zone. The remote sensing instruments (SUMER, CDS, EIT,
LASCO, UVCS, SWAN) present exciting new data on a wide range of
topics such as transition region dynamics, coronal plumes, coronal
holes, streamers, and coronal mass ejections, giving us our first
comprehensive view of the outer solar atmosphere and corona. These
data are complemented by energetic particle measurements produced
by the ERNE instrument on board SOHO.

Proceedings of the International Symposium on Large Telescopes,
held in Tokyo, Japan, November 29-December 2, 1988
We present certain empirico-statistical methods for the analysis of
narrative and nu merical data extracted from different texts of
historical character such as chronicles or annals. They are based
on several statistical principles worked out by the author, and
originally reported at the Third International Vilnius Conference
on Probability Theory and Mathematical Statistics in 1981. The
principal results were published in the papers [15]-[32],
[293]-[299], [304]-[319] and in the book: A. T. Fomenko, Methods
for Statistical Analysis of Narrative Texts and Applications to
Chronol ogy, Moscow Univ. Press, Moscow, 1990 (in Russian). See
also Part 1. The methods are applied to the problem of correct
dating of the events in ancient and medieval history. These results
induce conjectures on the redating of some important ancient
historical events. Generally speaking, we might say that the
commonly accepted "Modern Text book" of ancient and medieval
European, Mediterranean, Egyptian and Middle Eastern history is a
fibered (layered) chronicle obtained by gluing together four nearly
identical copies of a shorter "original" chronicle. The other three
chronicles are obtained from the "original" chronicle by redating
and renaming the events de scribed in them; we rigidly move the
"original" chronicle in its entirety backwards in time by
approximately 333, 1053 and 1778 years. Thus, the full "Modern
Textbook" can be reconstructed from its smaller part, namely from
the "original" chronicle for the 9-17th cc. A.D. See Appendix 1,
Figs. 101-104.
During the first decades after Einstein had developed his Theory of
General Relativity, the main effort was to understand the theory
and verify it experimentically. Meanwhile Genral Relativity is one
of the experimentally best confirmed theories and has become a
powerful tool for the investigation of cosmic processes where
strong gravitational fields are involved.
This book contains 16 contributions from well-known experts giving
a broad overview for non-specialists who want to learn how to
purely academic issues like gravitational wave detectors are now
put into reality.
IMAGE (Imager for Magnetopause-to-Aurora Global Exploration) is the
first NASA MIDEX mission and the first mission dedicated to imaging
the Earth's magnetosphere. This volume offers detailed descriptions
of the IMAGE instrumentation and of the image inversion techniques
used to interpret the data. Also included are chapters on the IMAGE
science objectives, the spacecraft design and capabilities, science
and mission operations, and the processing and distribution of
IMAGE's nonproprietary data products.
Both the high level of activity in worldwide space exploration
programmes and the discovery of extra-solar planets have spurred
renewed interest in the physics and evolution dynamics of solar
systems. The present book has grown out of a set of lectures by
leading experts in the field within the framework of the well-known
EADN summer schools. It addresses primarily graduate students and
young researchers but will be equally useful for scientists in
search of a comprehensive tutorial account that goes beyond the
material found in standard textbooks.
The quest for high resolution has preoccupied radio astronomers
ever since radio waves were first detected from space fifty years
ago. This venture was par ticularly stimulated by the discovery of
quasars, and led to the development of interferometer techniques
using baselines of transglobal dimensions. These meth ods have
become known as Very Long Baseline Interferometry (VLBI). Arrays of
radio telescopes situated all over the Earth (or even in space) are
regularly used for researches in radio astronomy, reaching
resolutions as small as a fraction of a milli arcsecond. The
technique also allows the measurement of the positions of the radio
telescopes to a few millimeters and so VLBI has become a major tool
in geodesy and the study of the rotation of the Earth. VLBI has now
passed the pioneer stage and is becoming a standard facility
available to astronomers and geodesists, requiring the coordination
of the operations of indpendently owned radio telescopes around the
world. In Europe observatories from England, Federal Republic of
Germany, France, Italy, Poland, Sweden and The Netherlands are
coordinated in their VLBI activity by the European VLBI Network
Consortium (EVN). The Programme Committee of the EVN allocates time
to scientific projects on a routine basis three times a year. The
Unites States has a similar arrangement of a network of independent
radio observatories, and joint experiments using 'Global Network'
are often made."
Emission lines provide a powerful tool to study the physical
properties and chemical compositions of astrophysical objects in
the Universe, from the first stars to objects in our galaxy. The
analysis of emission lines allows us to estimate the star formation
rate and initial mass function of ionizing stellar populations, and
the properties of active galactic nuclei. This book presents
lectures from the eighteenth Winter School of the Canary Islands
Astrophysics Institute (IAC), devoted to emission lines and the
astrophysical objects that produce them. Written by prestigious
researchers and experienced observers, it covers the formation of
emission lines and the different sources that produce them. It
shows how emission lines in different wavelengths, from ultraviolet
to near infrared, can provide essential information on
understanding the formation and evolution of astrophysical objects.
It also includes practical tutorials for data reduction, making
this a valuable reference for researchers and graduate students.
1. The Workshop and this Tome In the excellent bucolic setting of
SchloB Ringberg in Upper Bavaria, over 50 scientists assembled
during the week of 23-28 September 1996 to discuss recent results,
both theoretical and observational in nature, on the large scale
structure of the Universe. Such a topic is perhaps nowadays far too
encompassing, and is essentially all of what we used to call
"observational cosmology. " The original philosophy of the
organization of this meeting was deliber ated aimed at the younger
community and their contributions. As a conse quence, the content
of the presentations was refreshingly new, as it should be. In
spite of the deficiences caused by the lack of certain key
researchers in this field, for one reason or another, the final
result was rewarding to all. Although the conference was held in
Fall 1996, the contributions contained herein were submitted as
late as Spring 1998, thus the content maintains some degree of
trendiness. Originally the current volume was to be a "proceedings.
" This refers to the usual archival tome that fills one's shelf and
is rarely consulted, except to see the canonical group photo, which
by the way, we also have. Nevertheless, I wanted something more
than that. Although the field is rapidly changing, with so-called
facts in a state ofconstant volubility, now is a good time for
reflection prior to the commencement ofthe Sloan Survey, presumably
the definitive large-scale program of low- to moderate-redshift
galaxies in our lifetime.
AN OBSERVER BOOK OF THE YEAR 'A peerless intellectual biography.
The Glass Universe shines and twinkles as brightly as the stars
themselves' The Economist #1 New York Times bestselling author Dava
Sobel returns with a captivating, little-known true story of women
in science Before they even had the right to vote, a group of
remarkable women were employed by Harvard College Observatory as
'Human Computers' to interpret the observations made via telescope
by their male counterparts each night. The author of Longitude,
Galileo's Daughter and The Planets shines light on the hidden
history of these extraordinary women who changed the burgeoning
field of astronomy and our understanding of the stars and our place
in the universe.
The book provides a review of the hadronic final state measurements
at HERA in deep inelastic scattering. It covers general event
properties, particle spectra, heavy flavours, jets, event shape
measurements, QCD instantons and small-x physics. The emphasis is
on experimental results, providing quick access to the data
(complete up to fall 1997) for reference. The results are discussed
in the context of QCD.
A. GENERAL BACKGROUND "The foremost goal of the international
community in the area [of private space launch services] should be
to induce states to implement effective licensing procedures
applicable to commercial ventures for which state responsibility
may 1 exist. " 1. PRIVATE SECTOR PARTICIPATION IN THE SPACE
INDUSTRY In the first decades of the space age, military and state
security motivations indicated the direction of national space
programs. Now the development of space activities depends
essentially upon the possibility of recovering 2 investments.
Private sector-driven commercial endeavors in outer space have been
increasing exponentially and have experienced a significant
quantitative growth over the last years. Spacefarers promote
commercial participation of private companies in operations related
to outer space, and, thus, the private sector is now increasingly
providing satellite telecommunications, remote sensing, global
positioning and space launch services directly to its customers. In
this context, overall revenues for the worldwide space industry 3
amounted to US$ 82 billion in 2001. In the late 1990's the
transponder demand, in particular Ku- band transponders, was
consistently on the rise due 4 to the escalated utilization of
geostationary satellite transponders. Global positioning systems
have been playing an increasingly important role in navigation, and
remote sensing systems are mapping and documenting nearly 1 E. A.
