The aim of the inaugural meeting of the Sant Cugat Forum on Astrophysics was to address, in a global context, the current understanding of and challenges in high-energy emissions from isolated and non-isolated neutron stars, and to confront the theoretical picture with observations of both the Fermi satellite and the currently operating ground-based Cherenkov telescopes. Participants have also discussed the prospects for possible observations with planned instruments across the multi-wavelength spectrum (e.g. SKA, LOFAR, E-VLT, IXO, CTA) and how they will impact our theoretical understanding of these systems. In keeping with the goals of the Forum, this book not only represents the proceedings of the meeting, but also a reflection on the state-of-the-art in the topic.
The twentieth century was the era of "big science." Driven by strategic rivalries and fierce economic competition, wealthy governments invested heavily in national science establishments. Direct funding for institutions like the National Science Foundation and high-visibility projects, such as the race to the moon, fueled innovation, growth, and national prestige. But the big science model left poorer countries out in the cold. Today the organization of science is undergoing a fundamental transformation. In T he New Invisible College, Caroline Wagner combines quantitative data and extensive interviews to map the emergence of global science networks and trace the dynamics driving their growth...
The Marcel Grossmann Meetings seek to further the development of the foundations and applications of Einstein's general relativity by promoting theoretical understanding in the relevant fields of physics, mathematics, astronomy and astrophysics and to direct future technological, observational, and experimental efforts. The meetings discuss recent developments in classical and quantum aspects of gravity, and in cosmology and relativistic astrophysics, with major emphasis on mathematical foundations and physical predictions, having the main objective of gathering scientists from diverse backgrounds for deepening our understanding of spacetime structure and reviewing the current state of the a...
The origin and nature of gamma-ray bursts is currently one of the greatest mysteries in astrophysics. These tremendously powerful blasts produce more energy in a fraction of a second than our Sun does in ten billion years. Since their accidental discovery by American spy satellites over thirty years ago, astronomers have striven to understand these enigmatic explosions. It is only recently, thanks to an Italian-Dutch satellite, and powerful telescopes both on the ground and in space, that the mystery is beginning to be unravelled. Astronomers now realise that gamma-ray bursts are probably related to the birth of black holes in extremely distant galaxies. Flash! describes the fast moving field of gamma ray burst research, from the initial detection right up to the most recent discoveries. Based on interviews with leading scientists, this exciting book provides an inside view of the scientific challenges involved in unravelling the mystery of gamma-ray bursts.
The Third Microquasar Workshop (or the 'Fifth' Workshop on Galactic Relativ istic Jet Sources), was held in Granada, Andalucia (Spain) on 11-13 September 2000. The aim of this workshop in Granada, following the previous Microquasar Workshops in Greenbelt (1997) and Paris (1998) and the Workshops on galactic sources with relativistic jets in Jodrell Bank (1996) and Milton Keynes (1998), was to focus on the theoretical and observational aspects of microquasars. The study of microquasars, the sources in our Galaxy displaying powerful re lativistic jets, is a rapidly advancing field in astrophysics. The new instrumentation on ground (MERLIN, SCUBA, VLA, VLT) and aboard satellites (ASCA, BSAX, IS...
This book is a collation of the contributions presented at a major conference on isolated neutron stars held in London in April 2006. Forty years after the discovery of radio pulsars it presents an up-to-date description of the new vision of isolated neutron stars that has emerged in recent years. The great variety of isolated neutron stars, from pulsars to magnetars, is well covered by descriptions of recent observational results and presentations of the latest theoretical interpretation of these data.
The information received from BeppoSAX, Chandra and other instruments in the last two years has more than doubled the number of samples of Gamma-Ray Bursts localized and followed up for afterglow search. This has also increased the interest of astronomers in GRBs. This book reviews the research of the last two years and covers the global properties of GRBs, GRB afterglows, GRB host galaxies, cosmology using GRBs, and theories for GRBs and their afterglows. Theoretical and observational aspects are presented as well as tools for the analysis of the data.
In 1975 the Marcel Grossmann Meetings were established by Remo Ruffini and Abdus Salam to provide a forum for discussion of recent advances in gravitation, general relativity, and relativistic field theories. In these meetings, which are held once every three years, every aspect of research is emphasized - mathematical foundations, physical predictions, and numerical and experimental investigations. The major objective of these meetings is to facilitate exchange among scientists, so as to deepen our understanding of the structure of space-time and to review the status of both the ground-based and the space-based experiments aimed at testing the theory of gravitation.The Marcel Grossmann Meet...
