In this paper we present an efficient alternative to the power iteration method that is typically used to calculate k–eigenvalues, and corresponding eigenvectors, with deterministic transport codes. The alternative approach is based on a Krylov subspace iterative projection method called the Implicitly Restarted Arnoldi Method (IRAM). Only modest changes(More)
The search for an understanding of an energy source great enough to explain the gamma-ray burst (GRB) phenomena has attracted much attention from the astrophysical community since its discovery. In this paper we extend the work of K. and analyze the off-axis contributions to the energy-momentum deposition rate (MDR) from the ν ¯ ν collisions above a(More)
