Astrophysics: refreshed shocks from a y-ray burst
Granot, J.; Nakar, E.; Piran, T. (2003)GRB 030329 is unique in many aspects. It has a very low redshift for a GRB, z = 0.1685, and is therefore very bright and easy to monitor, making it the most well studied afterglow to date. It shows a supernova bump in the ... -
Hydrodynamics and radiation from a relativistic expanding jet with applications to GRB afterglow
Granot, J.; Miller, M.; Piran, T.; Suen, W. (2000) -
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 ... -

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 ... -
On the lateral expansion of gamma-ray burst jets
Granot, Jonathan; Piran, T. (2012-03)The dynamics of gamma-ray burst jets during the afterglow phase have an important effect on the interpretation of their observations and for inferring key physical parameters such as their true energy and event rate. ... -
