    The XRF080109-SN2008D and a decade of GRB-Jet-SN connection

    Full text link
    Last and nearest GRB-XRF 080109 has been an exceptional lesson on GRB nature. After a decade (since 25 April 08) we know that Supernovae may often contain a Jet. Its persistent activity may shine on axis as a GRBs. Such a persistent, thin beamed gamma jet may be powered by either a BH (Black Holes) or Pulsars. Late stages of these jets may loose the SN traces and appear as a short GRB or a long orphan GRB (depending on jet angular velocity and view angle). XRF are peripherical viewing of the jets. These precessing and spinning gamma jet are originated by Inverse Compton and-or Synchrotron Radiation at pulsars or micro-quasars sources, by ultra-relativistic electrons. These Jets are most powerful at Supernova birth, blazing, once on axis, to us and flashing GRB detector. The trembling of the thin jet explains naturally the observed erratic multi-explosive structure of different GRBs. The jets are precessing (by binary companion or inner disk asymmetry) and decaying by power on time scales of few hours, but they keep staying inside the observer cone view only a few seconds duration times (GRB); the jet is thinner in gamma and wider in X band. This explain the wider and longer X GRB afterglow duration and the rare presence of X-ray precursors.Comment: 11 pages, 12 figure

    Vacuum solutions with nontrivial boundaries for the Einstein-Gauss-Bonnet theory

    Full text link
    The classification of certain class of static solutions for the Einstein-Gauss-Bonnet theory in vacuum is presented. The spacelike section of the class of metrics under consideration is a warped product of the real line with a nontrivial base manifold. For arbitrary values of the Gauss-Bonnet coupling, the base manifold must be Einstein with an additional scalar restriction. The geometry of the boundary can be relaxed only when the Gauss-Bonnet coupling is related with the cosmological and Newton constants, so that the theory admits a unique maximally symmetric solution. This additional freedom in the boundary metric allows the existence of three main branches of geometries in the bulk, containing new black holes and wormholes in vacuum.Comment: Prepared for the proceedings of the 7th Alexander Friedmann International Seminar on Gravitation and Cosmology, July 2008, Joao Pessoa, Brasil. 4 pages, References adde

    Representing Veterans

    Get PDF
    Federal law has long deprived American veterans of certain fundamental legal rights enjoyed by non-veterans and attributable to veteran sacrifice. Federal case law, for example, denies veterans the right to bring an action in tort against the federal government to vindicate in-service injuries. And the United States Code deprives veterans of their right to robust judicial oversight of Department of Veterans Affairs (VA) service-connected benefit decisions. This pair of due process deprivations is compounded by the federal statute that prohibits veterans from exercising the fundamental right to counsel during the initial stage of the VA claims process. This Article examines the federal statutory scheme and pertinent case law that has long denied veterans the right to counsel throughout the VA veteran claims adjudication process, debunks the rationales underlying that law, and concludes by recommending that the federal government extend to veterans the right to counsel throughout the VA’s benefits adjudication proceedings
