Numerically calibrated model for propagation of a relativistic unmagnetized jet in dense media
Richard Harrison, Ore Gottlieb, Ehud Nakar
Relativistic jets reside in high-energy astrophysical systems of all scales. Their interaction with the surrounding media is critical as it determines the jet evolution, observable…
Limits on optical polarization during the prompt phase of GRB 140430A
D. Kopac, C. G. Mundell, J. Japelj +17
Gamma-ray burst GRB 140430A was detected by the Swift satellite and observed promptly with the imaging polarimeter RINGO3 mounted on the Liverpool Telescope, with observations begi…
Radio flares from gamma-ray bursts
D. Kopac, C. G. Mundell, S. Kobayashi +6
We present predictions of centimeter and millimeter radio emission from reverse shocks in the early afterglows of gamma-ray bursts with the goal of determining their detectability…
Phenomenology of Reverse-Shock Emission in the Optical Afterglows of Gamma Ray Bursts
J. Japelj, D. Kopac, S. Kobayashi +6
We use a parent sample of 118 gamma-ray burst (GRB) afterglows, with known redshift and host galaxy extinction, to separate afterglows with and without signatures of dominant rever…
New constraints on GRB jet geometry and relativistic shock physics
C. Guidorzi, C. G. Mundell, R. Harrison +23
We use high--quality, multi-band observations of Swift GRB120404A, from gamma-ray to radio frequencies, together with the new hydrodynamics code of van Eerten et al. (2012) to test…
GRB 130427A: a Nearby Ordinary Monster
A. Maselli, A. Melandri, L. Nava +63
Long-duration Gamma-Ray Bursts (GRBs) are an extremely rare outcome of the collapse of massive stars, and are typically found in the distant Universe. Because of its intrinsic lumi…
GRB 091024A and the nature of ultra-long gamma-ray bursts
F. J. Virgili, C. G. Mundell, V. Pal'shin +30
We present a broadband study of gamma-ray burst (GRB) 091024A within the context of other ultra-long-duration GRBs. An unusually long burst detected by Konus-Wind, Swift, and Fermi…
Magnetization Degree of Gamma-Ray Burst Fireballs: Numerical Study
Richard Harrison, Shiho Kobayashi
The relative strength between forward and reverse shock emission in early gamma-ray burst afterglow reflects that of magnetic energy densities in the two shock regions. We numerica…
