Book Description
Multibang Cosmos invites you to replace the big bang paradigm of a mysterious and unique cosmic origin and expansion by the observed local multibang expansions within a permanent cosmic recycling of all electronuclear material. The progenitors of stars and galaxies are found in expanding shells colliding with their neighbors along dynamic common walls that are home to groups of galaxies that will in turn migrate to clusters. Large clusters end up in the crushing gravitational claws of giant black holes whose final compacted destiny is a local maxibang event—the birth of a new expanding bubble. A new method is presented to compute galactic rotation velocities from Doppler shift field data whereby Newtonian dynamics is adopted and applied to point-like corrections on a disk or a stack of disks where velocities differ strongly from those from a sphere. The model is applied to calculate the corrected mass of four typical galaxies wherein dark matter is repelled. It is extended to a number of low- and high-surface-brightness galaxies for comparison. Corrections for linear large-scale cosmic features are briefly presented. The Standard Model of electronuclear particles is introduced by questioning the speed of gravity and the unknown parameter extensions toward the Planck units where a mare incognitum is found with a new hypothetical black force acting against the collapse of black holes.

Book Description
"Astronomy and Astrophysics Abstracts" appearing twice a year has become oneof the fundamental publications in the fields of astronomy, astrophysics andneighbouring sciences. It is the most important English-language abstracting journal in the mentioned branches. The abstrats are classified under more than a hundred subject categories, thus permitting a quick survey of the whole extended material. The AAA is a valuable and important publication for all students and scientists working in the fields of astronomy and related sciences. As such it represents a necessary ingredient of any astronomical library all over the world.

Book Description
This volume of important papers by one the world's leading astrophysicists provides a sweeping survey of the incisive and exciting applications of nuclear and particle physics to a wide range of problems in astrophysics and cosmology.The prime focus of the book is on Big Bang cosmology and the role of primordial nucleosynthesis in establishing the modern consensus on the Big Bang. This leads into the connection of cosmology to particle physics and the constraints put on various elementary particles by astrophysical arguments. Big Bang Nucleosynthesis has also led to the argument for nonbaryonic dark matter and is thus related to the major problem in physical cosmology today, namely, structure formation. The nuclear-particle interface with astrophysics also extends to the other topics of major interest such as the age of the universe, cosmic rays, supernovae, and solar neutrinos, each of which will be discussed in some detail. Each section contains historical papers, current papers, and frequently a popular article on the subject which provides an overview of the topic.This volume is testimony to the success of the integration of nuclear and particle physics with astrophysics and cosmology, and to the ingenuity of the work in this area which has earned the author numerous prestigious awards. The book, which is accessible to beginning graduate students, should be of particular interest to researchers and students in astronomy, astrophysics, cosmology and gravitation, and also in high energy and nuclear physics.

Book Description
For millennia mankind has watched as the heavens move in their stately progression from night to night and from year to year, presaging with their changes the changing seasons. The sun, the moon, and the planets move in what appears to be an unchanging firmament, except occasionally when a new "star" appears. Among the new stars there are comets, novae, and finally supernovae, the subject of this book. Superstitious mankind regarded these events as significant portents and recorded them carefully so that we have records of supernovae that may reach back as far as 1300 B. C. (Clark and Stephenson, 1977; Murdin and Murdin, 1985). The Cygnus Loop, believed to be a 15,000-year-old supernova remnant at a distance of only 800 pc (Chevalier and Seward, 1988), must have awed our ancestors. Tycho's supernova of 1572, at a distance of 2500 pc, had a magnitude of -4. 0, comparable to Venus at its brightest, and Kepler's supernova of 1604 had a magnitude of - 3 or so. Thus the Cygnus Loop supernova might have had a magnitude of - 6 or so, and should have been readily visible in daytime. A supernova in Vela, about 8000 B. C. was comparably close, as was SN 1006, whose magnitude may have been -9. While most of the supernova records come from the Old World, the supernova of 1054 is recorded in at least one petroglyph in the American West.
