Efficiency of internal shocks in magnetized relativistic jets
P. Mimica, M. A. Aloy
We study the dynamic and radiative efficiency of conversion of kinetic-to-thermal/magnetic energy by internal shocks in relativistic magnetized outflows. A parameter study of a lar…
Radiative signature of magnetic fields in internal shocks
P. Mimica, M. A. Aloy
Common models of blazars and gamma-ray bursts assume that the plasma underlying the ob- served phenomenology is magnetized to some extent. Within this context, radiative signatures…
An unusual stellar death on Christmas Day
C. C. Thöne, A. de Ugarte Postigo, C. L. Fryer +31
Long Gamma-Ray Bursts (GRBs) are the most dramatic examples of massive stellar deaths, usually as- sociated with supernovae (Woosley et al. 2006). They release ultra-relativistic j…
Variable Ly alpha sheds light on the environment surrounding GRB 090426
C. C. Thöne, S. Campana, D. Lazzati +16
Long duration gamma-ray bursts are commonly associated with the deaths of massive stars. Spectroscopic studies using the afterglow as a light source provide a unique opportunity to…
The missing link: Merging neutron stars naturally produce jet-like structures and can power short Gamma-Ray Bursts
Luciano Rezzolla, Bruno Giacomazzo, Luca Baiotti +3
Short Gamma-Ray Bursts (SGRBs) are among the most luminous explosions in the universe, releasing in less than one second the energy emitted by our Galaxy over one year. Despite dec…
