My name is Björn Ahlgren. I joined iTHEMS as a visiting scientist in February 2021 as part of my current postdok, and I'm otherwise based at KTH in Stockholm, Sweden. My field of research is astrophysics, where I work mainly on gamma-ray bursts (GRBs), which are some of the most violent explosions in the Universe. These phenomena are caused by the collapse of particularly massive stars, and by compact object binary mergers, and they can serve both as laboratories for physics under extreme conditions, as well as probes of the early Universe. In my research I focus on the intersection between theory and observations, where I try to develop and reconcile theoretical models for the emission mechanisms of GRBs with the best available observations, using statistical methods. My specialisation lying in applied statistics, I really enjoy interdisciplinary projects where I get to work with new ideas and new data. I'm excited to join iTHEMS and I hope I will get the opportunity to engage in new collaborations across different disciplines.
