TeV cosmic ray electrons from millisecond pulsars
Shota Kisaka, Norita Kawanaka
Recent γ-ray observations suggest that the γ-ray millisecond pulsar (MSP) population is separated into two sub-classes with respect to the pair multiplicity. Here, we calculate the…
Dark Matter Mini-halo around the Compact Objects: the Formation, Evolution and Possible Contribution to the Cosmic Ray Electrons/Positrons
Rui-Zhi Yang, Yi-Zhong Fan, Roni Waldman +1
Dark matter particles may be captured by a star and then thermalized in the star's core. At the end of its life a massive star collapses suddenly and a compact object is formed. Th…
Radio Monitoring of the Tidal Disruption Event Swift J164449.3+573451. I. Jet Energetics and the Pristine Parsec-Scale Environment of a Supermassive Black Hole
E. Berger, A. Zauderer, G. G. Pooley +4
We present continued radio observations of the tidal disruption event SwiftJ164449.3+573451 extending to \sim216 days after discovery. The data are part of a long-term program to m…
Gamma-Ray Burst Dynamics and Afterglow Radiation from Adaptive Mesh Refinement, Special Relativistic Hydrodynamic Simulations
Fabio De Colle, Jonathan Granot, Diego Lopez-Camara +1
We report on the development of Mezcal-SRHD, a new adaptive mesh refinement, special relativistic hydrodynamics (SRHD) code, developed with the aim of studying the highly relativis…
Simulations of GRB Jets in a Stratified External Medium: Dynamics, Afterglow Lightcurves, Jet Breaks and Radio Calorimetry
Fabio De Colle, Enrico Ramirez-Ruiz, Jonathan Granot +1
The dynamics of GRB jets during the afterglow phase is most reliably and accurately modelled using hydrodynamic simulations. All published simulations, however, have considered onl…
An observational imprint of the Collapsar model of long Gamma Ray Bursts
Omer Bromberg, Ehud Nakar, Tsvi Piran +1
The Collapsar model provides a theoretical framework for the well known association between long gamma-ray bursts (GRBs) and collapsing massive stars. A bipolar relativistic jet, l…
