A first-principle simulation of blast wave emergence at the photosphere of a neutron star merger
Christoffer Lundman, Andrei Beloborodov
We present the first ab initio simulation of a radiation-mediated shock emerging at the photosphere of a relativistic outflow. The simulation is performed using our code radshock t…
Can jets make the radioactively powered emission from neutron star mergers bluer?
Lorenzo Nativi, Mattia Bulla, Stephan Rosswog +5
Neutron star mergers eject neutron-rich matter in which heavy elements are synthesised. The decay of these freshly synthesised elements powers electromagnetic transients ("macronov…
Testing a model for subphotospheric dissipation in GRBs: fits to Fermi data constrain the dissipation scenario
Björn Ahlgren, Josefin Larsson, Erik Ahlberg +3
It has been suggested that the prompt emission in gamma-ray bursts (GRBs) could be described by radiation from the photosphere in a hot fireball. Such models must be tested by dire…
On the -Intensity Correlation in Gamma-Ray Bursts: Subphotospheric Heating with Varying Entropy
Felix Ryde, Hoi-Fung Yu, Hüsne Dereli-Bégué +3
The emission mechanism during the prompt phase in gamma-ray bursts (GRBs) can be investigated through correlations between spectral properties. Here, we revisit the correlation rel…
Sub-photospheric turbulence as a heating mechanism in gamma-ray bursts
Jonathan Zrake, Andrei M. Beloborodov, Christoffer Lundman
We examine the possible role of turbulence in feeding the emission of gamma-ray bursts (GRBs). Turbulence may develop in a GRB jet as the result of hydrodynamic or current-driven i…
Science prospects for SPHiNX - a small satellite GRB polarimetry mission
M. Pearce, L. Eliasson, N. Kumar Iyer +9
Gamma-ray bursts (GRBs) are exceptionally bright electromagnetic events occurring daily on the sky. The prompt emission is dominated by X-/-rays. Since their discovery over 50 y…
