Hydrodynamics and radiation from a relativistic expanding jet with applications to GRB afterglow
Granot, J.; Miller, M.; Piran, T.; Suen, W. (American Institute of Physics (AIP), 2000)We describe fully relativistic three dimensional calculations of the slowing down and spreading of a relativistic jet by an external medium like the ISM. We calculate the synchrotron spectra and light curves using the ... -
Images, light curves and spectra of GRB afterglow
Granot, J.; Piran, T.; Sari, R. (1999)We calculate the light curve and spectra near the peak and the self absorption break, for an adiabatic blast wave described by the Blandford-McKee solution, considering the emission from the whole region behind the shock ... -
Implications of the early X-ray afterglow light curves of Swift gamma-ray bursts

Impulsive acceleration of strongly magnetized relativistic flows
Granot, J.; Komissarov, S.S.; Spitkovsky, A. (2011)The strong variability of magnetic central engines of active galactic nuclei (AGNs) and gamma-ray bursts (GRBs) may result in highly intermittent strongly magnetized relativistic outflows. We find a new magnetic acceleration ... -

Is the Rapid Decay Phase from High Latitude Emission?
Genet, F.; Granot, J. (2009)There is good observationnal evidence that the Steep Decay Phase (SDP) that is observed in most Swift GRBs is the tail of the prompt emission. The most popular model to explain the SDP is Hight Latitude Emission (HLE). ... -

Genet, F.; Butler, N.R.; Granot, J. (2010)GRB 080503 was classified as a short gamma-ray burst (GRB) with extended emission. The origin of such extended emission (found in about a quarter of Swift short GRBs) is still unclear and may provide some clues to the ... -

Magnetic field decay in neutron stars : from soft gamma repeaters to weak-field magnetars'
Dall'Osso, S.; Granot, J.; Piran, T. (2012-06)The recent discovery of the weak-field, old magnetar soft gamma repeater (SGR) J0418+5729, whose dipole magnetic field, Bdip, is less than 7.5 x 10(12) G, has raised perplexing questions: how can the neutron star produce ... -

(2010)Type Ic supernovae have drawn attention since 1998 owing to their sparse association with long duration γ-ray bursts (GRBs). Although the GRB central engine generates ultra-relativistic jets, no relativistic outflows have ... -
