Dear colleagues,

our next EO meeting will take place this Thursday April 22 at 13:15 via Zoom.
The meeting will be online. To join access <https://stockholmuniversity.zoom.us/j/61497979368> <https://stockholmuniversity.zoom.us/j/65928545270> https://stockholmuniversity.zoom.us/j/67706307789
You will be able to enter the meeting room from 13:00. See below for other methods to participate.


This week Filip Samuelsson from KTH will present

Title: Radiation mediated shocks in gamma-ray bursts

Abstract: The roles of radiation mediated shocks (RMSs) and shock breakouts in the prompt emission of gamma-ray bursts (GRBs) have been studied for twenty years. However, so far, no such model has been fit to data due to their computational complexity. We aim to bridge this gap between theory and observation. In this talk, I will present an analogy that we have developed for this purpose, which is based on the similar evolution of the photon spectrum in an RMS and in repeated Compton scatterings with high-energy, thermal electrons. With this analogy we can accurately replicate spectra generated by a full-scale RMS simulation using a fraction of the computing time, allowing us to probe a large enough parameter space to fit the model to data. Finally, I will present fits to the prompt emission of the archetypical photospheric burst GRB 090902B.


See you then!
