Over the past few years, long-duration gamma-ray bursts (GRBs), including the subclass of X-ray flashes (XRFs), have been revealed to be a rare variety of Type Ibc supernova (SN Ibc). While all these events result from the death of massive stars, the electromagnetic luminosities of GRBs and XRFs exceed those of ordinary Type Ibc SNe by many orders of magnitude. The observed diversity of stellar death corresponds to large variations in the energy, velocity, and geometry of the explosion ejecta. Using multi-wavelength (radio, optical, X-ray) observations of the nearest GRBs, XRFs, and SNe Ibc, I show that GRBs and XRFs couple at least 1048 erg to relativistic material while SNe Ibc typically couple less than 1048 erg to their fastest (albeit non-relativistic) outflows. Specifically, I find that less than 3 percent of local SNe Ibc show any evidence for association with a GRB or XRF. Interestingly, this dichotomy is not echoed by the properties of their optical SN emission, dominated by the radioactive decay of Nickel-56; I find that GRBs, XRFs, and SNe Ibc show significant overlap in their optical peak luminosity and photospheric velocities. Recently, I identified a new class of GRBs and XRFs that are under-luminous in comparison with the statistical sample of GRBs. Owing to their faint high-energy emission, these sub-energetic bursts are only detectable nearby (z

Volume 19 continues the Reviews in Modern Astronomy with invited reviews and highlight contributions which were presented during the International Scientific Conference of the Astronomical Society on the topic "The Many Facets of the Universe - Revelations by New Instruments," held at the University of Cologne, Germany, September 26 - October 1, 2005. The contributions to the meeting published in this volume discuss, among other subjects, astrochemistry, astrobiology, cosmology, star and planet formation, and present overviews on new instruments in the infrared and sub-millimeter wavelength range. Highlight: Karl-Schwarzschild-Lecture by G. A. Tammann (Basel) "The Ups and downs of the Hubble constant."

Supernovae are among the most energetic phenomena in the Universe and - lated to almost all aspects of modern astrophysics including starburst gal- ies, cosmic ray acceleration, neutron star and black hole formation, nuc- osynthesis and ISM chemical enrichment, energy input to the ISM, cosmic distance scale determination, dark energy related cosmological acceleration, gamma-ray bursts, extra-solar system neutrino burst detection, gravity wave generation, and many more. Additionally, the past 15 years have been p- ticularly productive with many new results and new understanding due in particular to the closest SN in 400 years in SN 1987A in the Large M- ellanic Cloud, and the unusually bright and close SN 1993J and SN 1994I in the nearby galaxies M81 and M51, respectively. In addition, the disc- ery of the ?-ray burst GRB 980425 and its related supernova SN 1998bw, and the con?rmation of GRB 030329/SN 2003dh, tied the study of SNe and GRBs inextricably together. With the many developments since the last - jor supernova meeting in La Serena, Chile in 1997, we felt that it was an appropriate time to bring together experts and students interested in the subject for a meeting where SN and GRB properties and interrelationships could be discussed. The tenth anniversary of SN 1993J provided such an - portunity and, appropriately, the meeting was held in Spain where SN 1993J was discovered on the early morning of 28 March 1993 by a Spanish amateur astronomer, Francisco Garc ́ ?a.

Contrary to popular opinion, the story of Adam and Eve is not confined to the book of Genesis. It has roots in prebiblical myth and continued to evolve long after the Bible was completed. Bernard F. Batto traces the development of the Adam and Eve story from its origins in Mesopotamian myth to its reformulation in Genesis and beyond—including its expansion in Jewish epigraphs such as 1 Enoch and the Life of Adam and Eve, and its place in Christian innovations such as the apostle Paul’s thesis that Christ is a second Adam, and in the thinking of church fathers such as Irenaeus, who held that Christ recapitulates all humankind in himself, and Augustine, whose doctrine of original sin interprets the Adam and Eve story. Batto also examines gnostic teachings about a heavenly Adam and an earthly Adam, and surveys rabbinical attempts from the Talmudic period to find hidden meanings in the Genesis story. Islam’s emphasis on Satan’s role in seducing Adam and Eve is also discussed, and the book concludes with Milton’s unforgettable retelling of the Adam and Eve story in Paradise Lost. Batto’s goal is not only to reveal the many faces given Adam and Eve throughout history, but also to understand the divergent cultural and theological factors powering this long, evolving tradition.

This book presents some aspects of the cosmological scientific odyssey that started last century. The chapters vary with different particular works, giving a versatile picture. It is the result of the work of many scientists in the field of cosmology, in accordance with their expertise and particular interests. Is a collection of different research papers produced by important scientists in the field of cosmology. A sample of the great deal of efforts made by the scientific community, trying to understand our universe. And it has many challenging subjects, like the possible doomsday to be confirmed by the next decade of experimentation. May be we are now half way in the life of the universe. Many more challenging subjects are not present here: they will be the result of further future work. Among them, we have the possibility of cyclic universes, and the evidence for the existence of a previous universe.

Although much has been said and written about coincidences, there is a marked absence when it comes to the development of a comprehensive model that incorporates the many different ways in which they can be understood and explained. One reason for this omission is undoubtedly the sharp divide that exists between those who find coincidences meaningful and those who do not, with the result that the conclusions of the many books and articles on the subject have tended to fall into distinct camps. The Many Faces of Coincidence attempts to remedy this impasse by proposing an inclusive categorisation for coincidences of all shapes and sizes. At the same time, some of the implications arising from the various explanations are explored, including the possibility of an underlying unity of mind and matter constituting the ground of being.
