Investigating subphotospheric dissipation in gamma-ray bursts using joint Fermi-Swift observations
Björn Ahlgren, Josefin Larsson, Vlasta Valan +3
The jet photosphere has been proposed as the origin for the gamma-ray burst (GRB) prompt emission. In many such models, characteristic features in the spectra appear below the ener…

Thermal components in the early X-ray afterglows of GRBs: likely cocoon emission and constraints on the progenitors
Vlasta Valan, Josefin Larsson, Björn Ahlgren
The early X-ray afterglows of gamma-ray bursts (GRBs) are usually well described by absorbed power laws. However, in some cases, additional thermal components have been identified.…
