The goal of the project presented in this book is to detect neutrinos created by resonant interactions of ultrahigh energy cosmic rays on the CMB photon field filling the Universe. In this pioneering first analysis, the author puts forward much of the analysis framework, including calibrations of the electronic hardware and antenna geometry, as well as the development of algorithms for event reconstruction and data reduction. While only two of the 37 stations planned for the Askaryan Radio Array were used in this assessment of 10 months of data, the analysis was able to exclude neutrino fluxes above 10 PeV with a limit not far from the best current limit set by the IceCube detector, a result which establishes the radio detection technique as the path forward to achieving the massive volumes needed to detect these ultrahigh energy neutrinos.
This book will provide you with concise informative guides to avoid the pitfalls and misleading marketing when purchasing a telescope or other beginner astronomy equipment for yourself or others. This is NOT a buyer's guide for specific makes and models of equipment because such guides become quickly outdated and useless. This book will teach you how to determine for yourself what equipment best suites your needs. The misleading marketing of some telescopes is so bad that in my opinion it is even more flagrant than the marketing of "snake oil" alternative medicine products. But at least you won't be spending your health care money on beginner telescopes (that comes later after you are more involved in the hobby). With some products you can trust that a name-brand version is a good choice, even if you know very little about the product.. Unfortunately, that is no help with beginner scopes. Strangely, a large number of high end professional telescope companies make junk toy telescopes and use misleading marketing and advertising for these scopes. The aim of this book is to be a short, concise guide to becoming not only an educated consumer when shopping for a first telescope, but also to make sure you are not disappointed with your first experiences using an amateur telescope.
The Hubble Space Telescope has made some of the most dramatic discoveries in the history of astronomy. From its vantage point 600km above the Earth, Hubble is able to capture images and spectra that would be difficult or impossible to obtain from the ground. This volume represents some of the most important scientific achievements of the Hubble Space Telescope in its first decade of operation. Written by world experts, the book covers topics ranging from our own solar system to cosmology. Chapters describe cutting edge discoveries in the study of Mars and Jupiter, of stellar birth and death, of star clusters, of the interstellar medium, of our own Milky Way Galaxy and of other galaxies, of supermassive black holes, and of the determination of cosmological parameters, including the age and ultimate fate of our universe. This is an indispensable collection of review articles for researchers and graduate students.
