Electrons' energy in GRB afterglows implied by radio peaks
Paz Beniamini, Alexander J. van der Horst
Gamma-ray burst (GRB) afterglows have been observed across the electromagnetic spectrum, and physical parameters of GRB jets and their surroundings have been derived using broadban…
Constraints on millisecond magnetars as the engines of prompt emission in gamma-ray bursts
Paz Beniamini, Dimitrios Giannios, Brian D. Metzger
We examine millisecond magnetars as central engines of Gamma Ray Bursts' (GRB) prompt emission. Using the proto-magnetar wind model of Metzger et al. 2011, we estimate the temporal…
What can we learn from "internal plateaus"? The peculiar afterglow of GRB 070110
Paz Beniamini, Robert Mochkovitch
Context: The origin of GRBs' prompt emission is highly debated. Proposed scenarios involve dissipation processes above or below the photosphere of an ultra-relativistic outflow. Ai…
A Revised Analysis of Gamma Ray Bursts' prompt efficiencies
Paz Beniamini, Lara Nava, Tsvi Piran
The prompt Gamma-Ray Bursts' (GRBs) efficiency is an important clue on the emission mechanism producing the -rays. Previous estimates of the kinetic energy of the blast waves, b…
Shedding light on the prompt high efficiency paradox - self consistent modeling of GRB afterglows
Paz Beniamini, Lara Nava, Rodolfo Barniol Duran +1
We examine GRBs with both Fermi-LAT and X-ray afterglow data. Assuming that the 100MeV (LAT) emission is radiation from cooled electrons accelerated by external shocks, we show tha…
Charge Acceleration and Field-Lines Curvature: A Fundamental Symmetry and Consequent Asymmetries
Avshalom C. Elitzur, Eliahu Cohen, Paz Beniamini
When a charge accelerates, its field-lines curve in a typical pattern. This pattern resembles the curvature induced on the field-lines by a neighboring charge. Not only does the la…
